Kriesler 11-7 Radio Restore - Where there’s smoke there’s fire

[@olradguy]

I use post it notepad sheets to clean out the speaker gaps, fold it with the sticky sides back to back and work it into the gap, helps grab onto the dirt in the gap.

[@DavidTipton101]

That is an excellent idea olradguy, I will use that in future. I just did a speaker a few days ago and used masking tape so don't think I didn't listen to you, good one 👍😃

[@olradguy]

[@DavidTipton101]

G'day Pete, Yeah I thought I would get a schematic no worries but all I could get was a 1947 one that bears little resemblance to my radio. thanks for your comment 😅

[@Spasticlemur]

I truly enjoy watching you work David. I am an engineer for 3 small market radio stations, and the only tubes (valves) used in our FM transmitter are the 5CX1500A. I was trained in a time when everything was solid-state, except for the final power amplifier. Of course, transmission is different than reception in many ways. You are a true Master Crafstman. Very few people take the time to work the small details these days, it's truly a joy to see your restore these units. Have a great week, Sincerely, Randall Mann

My long suffering wife loyalty accompanies myself as I drag her (not literally of course) around yet another transport museum or classic bus rally and so forth. Occasionally she gets to play clippie if I take a vehicle along which she enjoys. Well done for sorting this one.

[@DavidTipton101]

Hi Simon. I did two RF8 radiograms which are later than yours but similar in design, they were fitted with Philips turntables not a Garrard unit like yours. I will leave the links below. There was also a Silicon Chip article on the RF5 which may be helpful. I have also done a few Garrard units you will find on my channel and I have another I have just completed which will be put up in a few weeks. It will be in part two of a HMV gram I did.

Dave, I’m really enjoying your videos. I grew up with Kriesler radios. I had a plum pudding sans case on my bed head at about age 10 when my passion for electronics took off. I have the radiogram, the bread loaf and several plum puddings, including a white one, and the newer triple throat with the knobs on each end all awaiting restoration. You have inspired me to get on with it. Sadly, at 66 I haven’t retired yet so time is of the essence. Meanwhile I’ll keep watching and learning. Thank you.

[@DavidTipton101]

Hi Robert, thank you. Kriesler seem to produce a better class of radio than some. I have at least one Bread loaf I haven't look at yet, I think the one with the knobs on the side are a model 11-41 or close to it. Hopefully you can get to tinker with them when you do retire 🙂

Fantastic restoration! I had the same speaker issue with the Kriesler 41-23 I restored, but I didn't know you could use clear plastic down the sides so I just ran it loudly face down for a few hours to work the dirt loose 😅 I thought about using felt but ended up using a modern dust cap, which I now regret. Lessons for next time! I might redo it at some point.

[@DavidTipton101]

Thank you Nebby. You might find that smaller speakers like your Kriesler 41-23 don't have enough clearance to get a piece of plastic in the gap. Your method should work. If you have a signal generator you can use that on a low frequency to get a larger excursion of the cone. Old film negatives might fit into the smaller gaps too. Thanks Nebby 🙂

[@neilforbes416]

At 1:04 to the right of, but right next to that garish greenish-blue boxy-looking set, the brown one! Yep, that's it! Our family had one of those for several years, a "Tasma"(Thom and Smith) brand set! That REALLY takes me back! WOW! Haven't laid eyes on one of them for AGES!

Ahh yes, looks like a Tasma baby. I have the 1001 model which was a basket case, no speaker, no valves, chassis bent in half and the case in three pieces. I rebuilt it and painted it black with a black and silver grill cloth, it looks and works great. I think Tasma used the same case before and a few years after the war. Your family had good taste 👍🙂

[@jeffreyhickman3871]

This looks like a radio 📻 fit for use in a restaurant, hence its “jukebox” like appearance. I remember eating out at a restaurant named “The Hub”, in my hometown of Glennallen, Alaska in 1978 for Mother’s Day. My parents, which are still living there, were about to be newlyweds. I do not remember if The Hub had a jukebox or not, or a radio like you restore. I remember the unique smells of the place. One ☝️ like food 🥘, one ☝️ like perfume of some sort. I enjoyed being here, but unfortunately, the restaurant burned down in the spring or summer of 1979, if I’m not mistaken on the year. This radio looks so worthy of such a restaurant, but only if it doesn’t burn down. This radio has a hint of the 1950’s and 1960’s, and hippies. Seems as if houses are styled alike, as far as this. Radios 📻 and houses go hand 🤚 in hand 🤚 I guess. Like the radio takes on the same generation or era as the house. I really like this radio. Too bad it isn’t a coin operated radio 📻 like the ones I told you about earlier. Also, this radio should have miniature 45’s inside. Better yet, this radio be the same size as a jukebox, with 45’s in it.

[@DavidTipton101]

It won't burn down now, it works a treat 👍

[@Jammerk40]

Very nice job! I like how you fixed the speaker looked original afterward. Everything turned out nice and the radio is back at it's peak for another many years!

VERY NICE 📻 radio collection. I forgot to tell ya that 📻 capacitors hold a charge, even when the 📻 radio is unplugged. I do 👎 not know if an isolation transformer can "ground", or "dump" this stored voltage. I 👌 know a shock from a capacitor can be potentially dangerous, especially in persons with ❤ heart problems. You can usually discharge capacitors by putting a screwdriver across the terminals, but, regarding these old 📻 radios, you want to properly discharge capacitors, if they're 👍 good, instead of ruin them. Sounds 👍 like ya have some 🔥 hot capacitors, which probably have gone ☝ up in value. Just be careful 👎 not to burn yourself, or be hurt, if the capacitor decides to explode. Also, be careful of starting an accidental 🔥 fire. Your friend, Jeff.

[@DavidTipton101]

Hi Ron, I'm doing another 11-7 as we speak. The schematics for theses Krieslers are a nightmare, there are something like 21 or so variations of the 11-7 design. You need to use the valve line up in your radio to determine the correct schematic to use and it is usually a base schematic with a list of addendums. There are circuit diagrams on Radio Museum, in the AORSM and here: www.tuberadio.com/robinson/museum/Kriesler11-7/ The quality of all the diagrams are woeful. Good Luck 🙂

[@waynethompson8416]

David !!!!!!!!!!!!!!!!!!!!! So good to see you back working your magic! This set was by no means junk, but you still managed to work magic with it. Hoping you have a stash of many more to work on....love your videos. I now have 2 Garod V Neutrodyne's here. Neither would work as is...one doesn't even have valves! Speaking of such, the ones used in this set are 01A's. I am going to have a heck of a time finding those! Not sure that my tester will even test them either...haven't found the tube tester either. Most likely I need to recap the tester too. When I finally do start on the restoration of the Garod V Neutrodyne, I am going to do something with one of the cases that will probably make some people scream. I am going to take "everything" out of the case, clean the case, then sand it down and re-stain it to have a nicer case. The second one already looks great other than being a bit dirty. If you provide me with an email address I can send to, I will send you photos of the new one. I actually have several things to work on...problem is lack of parts, time, and money!!! Don't know if my phone would do well enough to make a video for KZbin or not, can't afford a "real camera" right now. But maybe I will make a video of recapping the tube tester, my Hallicrafters 8R40, and the Garod's. Again, glad to see you back at it! Looking forward to many more videos! Say HI to the wife too...and tell her I said THANK YOU so very much for allowing David to do this wonderful thing!!!

[@DavidTipton101]

Hi Wayne, Thank you for your kind comments and I passed on your thank you to my wife for allowing me so much freedom to pursue my hobby, she's wonderful. If you haven't done so, maybe look for a radio club as they usually have a valve bank or know where you may get the 01A valves, a Google search may find some leads too. If you have extra valves you may not need a valve tester as you can shotgun problems by swapping valves around. As far as restoring the case I think you should do what you want, it's your radio. If you restore a vintage car you don't just get the motor running and put it on display. I'm reluctant to publish my email but there may be a way in KZbin that's just become available, I'll check that out. The phone cameras are great and give excellent results for KZbin. Cheers, David 😀

Hi Dave! Another great restoration. You had not mentioned if you had put it back to tube rectifier.

I'm wondering if you, or one of your subscribers who may see this comment, have acces to an 11-7P schematic? I have a few of the 11-7 radio variants on my shelf, and the schematics to match, but only up to version H. Perhaps Kriesler gave up on amending schematics after that version. I've compiled a spreadsheet with all of the valve variants over version updates. There are many subtle changes through time, and it is very, very difficult to determine which radio you are looking at. Thanks for the great radios Kreisler.

I would be most interested what was used in the original power transformer/rectifier valve configuration. In earlier days, transformers were rewound, but labour costs are prohibitive (been for some time). You've done a very thorough job, and certainly a very collectable and operational radio with many years of service ahead..

[@DavidTipton101]

Hi jmcgatkinson, I only ever found the early schematic for this radio and an extensive list of modifications leading to the radio I have. The original rectifier was a 6X5 (octal base) but that was updated to a EZ82 (noval base) which is what I think was in this radio. I don't know what configuration the power transformer would be as far as the 6.3V windings are concerned as they often had 2 windings, one for the heaters and another higher current winding for the rectifier. Other Kriesler circuits of the same era had two windings of 6.1 volts. You are correct about transformer rewinding but I am getting two rewound at the moment by a retired gentleman for a reasonable price. Thank you for your comment jmcgatkinson 😀

Very nice restoration there David. The display in Canberra reminds me of the HRSA display at the library here in Bacchus Marsh some years ago. If you’re passing through sometime it might be worth visiting the blacksmiths cottage as they have a Marshman Music Master.

[@DavidTipton101]

Hi Wenlocktvdx, I go to Melbourne every Christmas so I will drop in on the way to Ballarat. I have a Marshman radio I picked up in Geelong. I think there is a photo of the Bacchus Marsh one online.

[@Wenlocktvdx]

Yes, I think that one is the main one you will find online. Wenlock

Nice work and great video. I have this same radio model but mine has the EL33 output tube instead. I believe the rectifier is different between these types also, mine is a 6X5GT. Nice radios and are certainly very nice sounding.

Hi Aron, Thank you. Mate, there were no less than 20 versions of this model with different valves, transformers and resistor combinations., I pretty much gave up and winged it. In the end it works and sounds really good 👍🙂

[@glennsprigg2378]

Hi again Dave. I know this is an older post, but you are certainly my latest Super-Hero!! :-) Faultless, with regard to every aspect, once again, mate. Re: your "Problematic Schematic".... Yes, there were a LOT of variations in Valve-LineUps, and more, for that 'Model' it seems! I'm assuming you found/referred to the Model 11-7/11-9 info from 'radiomuseum.com'. ? That was a slightly later model, whereby although the outside looks basically the same, the external difference was that the 'SW' band appeared at the TOP of the dial indicator panel. YOURS, is the older original 11-7, that had the 'SW' band at the BOTTOM of the panel!! I found a Site, (had nothing else to do! hahaha..), that explains the differences, including tubes. There's a lot of interesting info about 'Kriesler' on that page!! As well as links to schematics at the bottom. The TOP one on that short list 'should' be the schematic for your Radio!!...... www.tuberadio.com/robinson/museum/Kriesler11-7/ It seems that yours is/was the original 1947 model. (Not the later 1948 or later?). Yes, it's been previously modified by someone, including the Valve-LineUp. Have a great day David! Now I'm back to your Posts!!!! :-) P.S. I originally thought that the letter 'K' on your radio had a broken off vertical bar on the left side of the 'K' letter!! Obviously, it is not! :-)

[@DavidTipton101]

Hi Glenn, I can't remember if I saw that page you linked or not. I was aware of the SW on the top or bottom and thought I mentioned it in the video, it may have been cut out of the video. Kriesler would issue a schematic then add written addendums as they changed the design or parts, they didn't mark the chassis to say what amendment level the chassis was either. It was very difficult to follow. I usually get the schematics from Radio Museum, this radio is listed in the AORSM as well 👍🙂

[@DerekHerbst747]

This is a fun repair! I replace the 2 or 3 wax coupling capacitors at preamp and power amp stages as a rule before powering up. this saves a lot of hassle and lets me do a first power-up with more confidence. I have the same Leader LSG-11 Sig Gen and I find it to be accurate enough without using a frequency counter to confirm the dial settings. The only negative comment I have is that it generates too many overtones which can be confusing, especially on the Shortwave bands. I'm thinking of doing a mod so that I can enable/disable overtones by having a bias shift switch on the oscillator tube to make the sinewave more pure.

[@DavidTipton101]

I agree Derek and if I wasn't videoing it I would change those caps too but that would be no fun and it would hide the effect a leaky coupling cap has on the radio 😄 The tone on the Leader is a bit unclean and looks ordinary on the oscilloscope but overall works pretty well, if I'm having trouble I switch to the electronic generator. As always I appreciate your support, thanks Derek 👍🙂

[@EmilioGarcia-fr5po]

Have a question my first time ordering a variack. The little red one 2000 volt wouldn't need anything with it. Just it to add voltage? Thanks for allways answering

[@DavidTipton101]

@@EmilioGarcia-fr5po Hi Emilio, The Variac is used to control the mains supply from somewhere near zero volts to full voltage. Mine will actually go higher than the input voltage so up to maybe 250 to 260 volts from a 235 volt input. If you use a dim bulb which is highly recommended you may not need a Variac, you can control the voltage using various wattage bulbs. My Varic is rated at 500VA which means it can supply 2 amps at 240Volts. 500/240 = 2 amps. Most of the equipment I operate run at about 0.2 Amps. I hope that helps 🙂

[@janetwinslow2039]

Another of your great restorations. Are all Australian radio IFs 455kHz? In the UK they are anything from 450 to 470 kHz- depending on the manufacturer and sometimes even on the region - to minimise image problems. A top tip for SW alignment: I use a nearby SW digital radio to pick up the LO so you know you're not inadvertently peaking up on the image.

[@DavidTipton101]

Hi Janet, thank you. 455kHz is the norm but there are variations of that as in the UK. I think I recall one being 457.5 or something 🤦‍♂️ That's a great tip on the short wave, I don't have such a radio but I could use an oscilloscope I guess 🤔

[@janetwinslow2039]

@@DavidTipton101 I doubt a scope will be useful unless it has a frequency readout. A cheap SW radio is a very useful piece of test gear. When at the top end of SW doing an alignment (where images are a problem), if the instructions say inject 15000 kHz you'll likely receive it at the real point and the image. If you tune the digital radio to 15455 kHz, you'll know when you're on the real signal and not the image because you can hear the LO on the digital radio.

[@DavidTipton101]

@@janetwinslow2039 Yes, I meant use the frequency readout on the scope, I would disconnect it before making an adjustment though. The radio would be better.

I remember growing up in the 50's seeing in my grandfather's shed, several Super triple heterodyne or triple heterodyne radio chassis, cannibalised for their solder. As I was interested in radio's, he gave them to me to fix, but they were missing capacitors, resistors and many many other parts. Needless to say, they went to the tip.

[@DavidTipton101]

I can't imagine there was enough solder there to salvage Lone Monaro but most radios end up in the tip. I had a CV8R Monaro for a number of years 😃

Being resourceful, he also salvaged solder also from tin cans by placing them on an open fire and collect the small pieces of solder from the cold embers.

In read the story about the Kriesler company. Originally, the founders Weingott (a Jewish name) intended the name to be spelled "Kreisler" (after the famous composer and violist Fritz Kreisler). But they changed the name to avoid legal complications. "Kreisler" is a German name which means "grain trader". The company was based in Sydney. Interesting.
