NZ Phoenix Radio Pt 3.1 -Addendum- Rola Speaker Restore

In part 3 I finished the Phoenix radio but it had a temporary speaker fitted while I waited for parts for the original to arrive. See how I restore this speaker to working condition and to almost original looks.

I rebuilt my 1983 Sansui speakers three years ago. At 33 years old, they were literally brand new when compared to your phoenix radio speaker. I fully appreciate what you went through. Another great job.

[@DavidTipton101]

Hi videolabguy, yep the bugs got to my one, it works well though, one of my better sounding radios 🙂

[@redrobbosworkshop]

David your work and videos are superb. I've been watching them back to back. PVA is the way to go with speaker surrounds. Be careful spraying the cone, in addition to your warnings on potential coil rubbing, the sound of the speaker will also change.

[@DavidTipton101]

Hi Red Robbo, I will use PVA in future. I take your point with spraying the cone through I haven't noticed any difference, I guess you are talking about stiffening the suspension part with paint I doubt it adds much weight as it's a very light spray. Thanks 🙂

[@ottodydaktyk]

Remarkable. I thought you were going to leave the replacement speaker in this radio. Well done, David, well done. (Also, I've never seen a radio dial where the numbers ascend from right to left. I learn something new every day!)

Hi David, back in the day when I re-coned JBL P.A speakers and the like, we use to source cones, voice coils etc from Queensland Speaker Repairs if my memory serves me correctly. They would also supply the appropriate adhesives and shims to centre the voice coil. Probably more expensive than eBay/China, but the owner knew his stuff and we were always supplied kits that fitted within days.

[@DavidTipton101]

Hi Graham, thanks for the info. They aren't far from me and I have their card. They are more expensive and if I have a radio worthy of the expense I'll go and see what they can do. The foam suspension supports I use have a limited life. I should go and get some adhesive from them though 🤔🙂

When you're at the stage of having nothing to lose but you want to retain as much originality as possible, you can't really do better than this. Looks original but very clean from the back and what it looks like from the front is neither here nor there bacause of course it can't be seen with the radio assembled in it's case. This radio needs nothing doing for a very long time now, it'll probably be around 100 years old before it's ready for the next overhaul!

You can invert the speaker surround too to make the bulbous bit in the speaker, many vintage japanese speakers were like this to allow closer mounting

Yeah, tried that, I can't remember why I discarded the idea, did the bulb touch the basket... not sure.

[@JerryEricsson]

In 1977, I was preparing to leave the United States Army as my second 3 year hitch was coming to an end. To that end, my unit released me early from my field recruiters duties (Didn't want a recruiter who was getting ready to get out, you know!) So to kill the time, I enrolled in a community college to study auto mechanics. One of the first things the instructor told us was to remove all rings and metal watch bands before going to work in the shop area in fact we would get demerit points that counted against our overall grade should we be found wearing such items. The reason, of course was that such items could easily short out electrical circuits should the ring come in contact with the positive wire and ground. This short would pass enough amps to melt the gold in your ring, or the metal in your watch band and also burn your finger or wrist very badly, in fact, he told us of students who lost their fingers to such incidents. Of course the chance os shorting out 240 volts or higher in a radio chasse may not be as probable, however the chance does exist. This is why I wear no jewelry or metal banded watches when tinkering with my hobby builds of different circuits. Just a thought I figured it would not hurt to share here. Of course now that I lost my wonderful wife of 51 years and 4 days to cancer last summer, I no longer wear a gold wedding band with that little diamond in it anyhow. I did wear it for a few months to honor her but people began to talk of my mind getting a bit weak after the hell of seeing cancer eat her alive so to please them I did remove it. I keep it in a small box on my dresser and still look at it every night before retiring, a sort of good night to that wonderful woman who gave me such joy for so very long. Never take your lovely wife for granite as some day you may be without her, and God how that hurts.

[@DavidTipton101]

Hi Jerry, thanks. I am aware of the risk with finger jewellery and I didn't wear a ring for my entire working career for that reason. I feel the risk here is low as I never put my finger in a live set and wearing my wedding ring outweighs the risk of an angry wife. If it was up to me I wouldn't wear it for the reason you stated. I am all to aware that the time is approaching when one of us will leave the other, I just hope it's me first as I don't want to endure the pain. Thanks Jerry.

[@jeffreyhickman3871]

I’ve watched Shango066 do this before. Original speakers need the treatment. There is also speaker 🔊 reconing glue to cover all of the speaker 🔊 paper 📝 with, such as if the speaker cone is punctured or torn. If you’ve ever had a problem with a raspy sounding speaker, and it’s binding, you probably have dirt between the speaker coil and the magnet, or a damaged speaker coil, which is binding and rubbing against the magnet. If a speaker is damaged on the outside edge, this can lead to buzzing. Speaker reconing glue can work for this, even if the speaker cone is severely deteriorated. Makes it sound like brand new. The only time to replace a speaker is if it is beyond all methods of being able to save it. Often, new speakers are not made to the specs of the original ones, and fitting it in the radio can present a challenge. I’ve seen this with Shango066 and Radiotvphononut. I hate to replace original parts, since this often takes away from the item being original. Speakers must be an exception, since they are usually hidden behind a speaker cloth.

[@DavidTipton101]

This speaker is still working and has the better sound than most of my radios 👍

[@MicSokol]

When you glue the rubber to the cone you shouldn't leave the glue to dry as it is required, as in this application that is not necessary, it will stick good enough. For the outer side of the rubber, just roll it outwards, the bump on the rubber ring should keep it in place, then use the same type of adhesive that you used on the cone but this time let it dry as required by the glue manufacturer. You should work the glued parts with your hands to assure firm bond. Also I would vacuum the space where coil sits. When I was a kid I used to repair speakers, I wish I had KZbin then. I really enjoy you videos, keep em coming.

Hi David - just came across this one today - so have watched all 3.5 parts at once. A job that seemed to have you rather taxed on a number of occasions. Interesting and efficient speaker repair - I used to use a fairly crude system for repairs to old speaker cones that had holes in them using tissue paper and glue which I built up in layers. I'm not to sure about the thinly veiled references to NZ radios that do not even have circuit diagrams... :)

[@DavidTipton101]

Hi Kenneth, most jobs are taxing for me as I'm only learning as I go 🙂 I can usually repair holes in speakers using the same method you suggested but this had extensive damage to the suspension and if I repaired that it would have killed off the bass. I only found out later but the radio was made in NZ and sold in a store in Brisbane under the name Phoenix. I couldn't find any schematics for it even under the parent company radios, there were plenty of diagrams for other NZ radios however 🙂

[@kennethgibbons2487]

Hey David - I do understand you are "learning as you go" don't take my comments as criticism - they are not. I love watching your work - in some ways you are much like me with your comments and your humor - and I am not one of these people who get upset over comments on NZ!

I found on eBay complete paper cones with wrinkle edges for small speaker repairs for about $12.00 I think that's a little high for a piece of paper.

The cone is too ripped and narrow to replace with a modern equivalent. Do people press their own cones in this case? Seems like a lot of work for a one-off repair. BTW, Tubesandmore sells a product called Service Cement that's supposed to work well with speaker foam.

[@DavidTipton101]

Hi SY, this was my first attempt at speaker repair and it wasn't pretty. It works and sounds very good though, one of my better sounding radios. I have an early 30s speaker that needs a new cone and after hours of searching found one that should do the job, It hasn't arrived from Hong Kong as yet to confirm. It should be possible to fabricate a new cone, maybe from stiff plastic sheet or doped paper or doped thin cardboard. I take it you are in the US and you have speaker repair companies that could supply parts or do the repair, cost would be a consideration in that case. I can get speaker adhesive locally.

Hi Harald, I use foam because it was all I could get at the time and it's still hard to get paper cones. In the US you can buy replacement speaker parts and kits for a reasonable price but not here.

I can keep a supply of foam suspension surrounds for most speakers and it doesn't require replacing the entire cone and voice coil. Thanks Harald 🙂

Hi David, I've just noticed your comment. See my comment today and that might help you to source speaker cones, voice coils, dust caps etc.

[@1959Berre]

Aaahrr!! When you said "contact adhesive" I cringed. That stuff contains toluene (C6H5CH3) which means it destroys foam surround. Always use PVAC glue (like white "woodglue") It has a fair open time, which allows for correcting the position of the foam surround. BTW, if you first glue the ring to the frame, it already sits in the correct position. Then glueing the inner ring to the cone is much easier. Instead of putting a weight on top, use clothespins to clamp the surround.

[@DavidTipton101]

Haha... this was my first try at repairing a speaker, I have improved since then and I now use a PVA based adhesive. Having said that, I changed the dial lamp in this radio a few months ago and the speaker and it's surround are still in first class condition, thanks for the tip 🙂

Hi manoj, you can repair holes with small pieces of kitchen paper, coffee filters or similar soaked in PVA glue or contact adhesive. If the repair is on the suspension area of the speaker use the contact adhesive as it remains flexible. If you make the repair too heavy on the suspension area you will stop the cone moving full travel which will dampen out the bass sounds so keep it as thin and flexible as possible.

Your skills are amazing. I know how hard it is to complete such work. Are you from NZ ? Thanks a lot for the video.

Hi Chathura, thank you. No, I'm from Australia, cheers 😃

Great repair job. I usually use the rubber surrounds as they tend to last far longer. I’ve done a few similar repairs when restoring 1970s-1980s Japanese radio cassettes (boomboxes) that I collect (hoard). Can’t do tuner repairs/realignments though. Are you interested? I have a Sharp GF-9090 from 1977 that needs a little tuner work. I’m at Mt Gravatt, Brisbane.

[@DavidTipton101]

Hi James, are you saying you can get rubber surrounds instead of foam rubber like I used, that would be better I imagine. To be honest I wouldn't want to do a radio like the Sharp, I struggle with the modern stuff and I'm still trying to get my head around valve radios. Thank you anyway 👍🙂

[@revelairfanman6171]

Hi David, Thanks for your response. Yes the rubber surrounds do last much longer than the foams - you usually only get around 10 years out of the foams depending on temperature and storage method. The FM tuner of the Sharp works fine apart from the situation where Triple J (107.7) is right up the top of the dial (max adjustment). It needs to adjusted back to 107.7 instead of 108+. The signal generator method is what’s used but that’s all I know. :-)

Great work Dave, where do you get your templates for all the labels you make?

[@DavidTipton101]

Hi Terry, thank you. I make all the labels and dials on my PC. If I have a sample label or dial plate I scan it into the drawing program and type the text and graphics on top of it. I remove the scanned original and am left with a close copy 👍🙂

EVA is better glue

[@DavidTipton101]

Totally agree Ian but I could'n find anything to keep pressure in the joint while it dried so I opted for contact. I will be using EVA in future though particularly after that effort :-)

Finish trim looks a little crooked.

[@DavidTipton101]

On the speaker or radio? The speaker surround might be a little off, it was my first attempt and I used the wrong glue, I'm a bit better at it now 🙂

[@markmurto]

@@DavidTipton101 the radio face trim on the outside where the dial is seen looks a bit crooked. The speaker job was great. I've done the same way. But I would just go bonkers if the front of the radio was not perfectly straight. You did a great job on it though.

[@DavidTipton101]

@@markmurto Yes, it is a bit off, I'll fix it when I pull it down again, I have to realign the dial at some point, I didn't do it right the first time.

@@DavidTipton101 its quite amazing. I watch Techmone, and your channel, way from over there in England, from California USA, and its just like next door real time talking. You know the Bible is sure right when writings predicted that men would have no stop to the inventing. In the next twenty years, can you even guess? That is of course if we stay free of the CCP. and other plan-demics and such. Great channel. Keep on keeping on.
