Bush Dac90A - Cracking Up

[@mikekarpaty3871]

Another masterpiece of radio restoration. Thank's for this Chris. Now its time for me to get started on my DAC 90 😊

[@allthegearnoidea6752]

God I created a monster. Buy a Dac 10 it’s the sexy curves

[@mikekarpaty3871]

Got one Chris 😂

[@GeorgeChristofi]

What are you doing? Playing with a bush and then showing us the crack! Not only showing us the crack but filling it in with sticky stuff and then the result.. oooerrr missus... you might have to go 18 plus only. It has turned out good Chris, very entertaining.

[@allthegearnoidea6752]

And next time I will be playing with a vibrator! Thanks George regards Chris

Wonderful to see you back again, Chris. I'm not a DAC90 fan, either, but that's a good result.

Great to see you back Chris. A good watch with a cuppa. I really like the look of the DAC90 and it has a great tone 👍

[@allthegearnoidea6752]

It does sound good for a small set. Thanks for watching regards Chris

[@davidv1289]

Chris, your wit and wisdom have been sorely missed. Very nice to have you back! My first shock was from a 5 - tube (I mean valve) AC/DC set. Taught me not to stick my fingers up its skirt. Thank you for an entertaining video. Regards, David.

[@mikeatlantis6843]

Good to see you back chris.enjoyed the restoration of the DAC 90.it looks and sounds great after you have gone through it and sorted everything out.i thought £25 was okay as I paid £50 for mine, but no crack in my Bush!hope you keep it as you got it to look very nice indeed

[@allthegearnoidea6752]

It is a shame about the crack I don’t know how I missed it first time around. Still it works well. Thanks for watching regards chris

[@SoddingaboutSi]

You must have had Covid as you had no taste, but I see you better now as your taste has improved on the radio front.

[@davidkerr8030]

Very good to see you back again Chris. The radio turned out pretty well considering all the rust. Thankfully, nobody had "got at it" by the looks of things - all components looked original. 25 quid wasn't a bad price - I've seen basket cases on eBay going for more than that! One the one I restored, the across the mains cap had blown and taken out the audio output transformer. Fortunately, RS still stock one very similar, if just a tad bigger, but you can make it fit with a bit of fiddling. Thanks again for another very entertaining video.

[@markpirateuk]

I have restored quite a few DAC90A's, a pleasure to work on & a good performer. Your set has a grey dropper, so makes it 1950, later models changed to a green dropper. Personally, I like the appearance of the DAC90/A, form follows function, nice simple design. the most popular vintage radio in the UK, they sold well until the last one left the production line in 1959

[@allthegearnoidea6752]

Yes I read about the colour of the dropper somewhere your quite right. Thanks for watching and comments regards Chris

[@markpirateuk]

@@allthegearnoidea6752 There were various cosmetic changes over the years, three different front knob styles & several different dials in various colours. The circuit remained the same for all production years, Bush certainly got it right after the issues with the original DAC90.

[@RandallCrook]

I have a Little Nipper sitting up in my "Man Cave" to restore. It's in good nick visually but I still haven't had the motivation to finish my dim bulb test set so I can work on it. You know Isolation tranny, and variac + bulb. I really should get off my ass and get it done. I might now I have seen your work on the Dac90A. Then again probably not. ;) Good to see you back, have missed your edutainment a lot.

[@allthegearnoidea6752]

Yes you should get it done now the dark nights are coming. Thanks for watching and comments regards chris

[@Radiocruncher]

Great to see you back Chris and hope you are doing okay. Shame about the cracks but it’s like that for a lot of them. I have 3 here and they are all cracked. I do like these sets, they look great on display and are easy to work on. At least the output transformer was good on yours. Cheers Graham

[@allthegearnoidea6752]

Thanks Graham. Yes the transformer is fine for now but the are a week point

[@steelcity321pb6]

Hi Chris, As the ‘budget’ radio market went after WW2, Bush manufactured the best of the small AC/D.C. sets. The reason DAC90, and the DAC90A radios remain so plentiful was the fact a fair amount of thought went into their design and development; their performance was as good as any AC only radio costing at least half as much again; they gave a pleasing tone, and they were competitively priced - Bush knew all of that would appeal to consumers. Those radios bring back pleasant memories in the service centres where I was employed. Like you say, they are straightforward to work on, and above all, they are reliable. Strange as it might appear, those Bush radios were were coming in for repair as late as the mid 1980s, albeit in very small numbers. Look after that radio, and it will never let you down. I own 19 of them, and each one is in full working order. All the best from Phil p.s, you’ll enjoy working on the Bush TV12 📺 television, as old 405 line tellies go, they too are fairly plentiful.

[@allthegearnoidea6752]

I enjoyed working on the TVs but I have run out of room going to have to get rid some before I buy anymore. Probably should have found a Dac 90 that didn’t have a broken case. It was easy to work on and performs very well. Hope you enjoy the house move. Best regards chris

She's a runner :-)) Spoiled all the fun, no smoke!! 🥸 Social distancing >> 😷 You have been noticed by your absence!! 🫂

[@allthegearnoidea6752]

Thanks feel better now and it’s good to be back

[@holmespianotuning]

I think it’s a much more attractive case than the bulky DAC10, although the latter was probably better quality.

[@Northern-Rambler]

I always knew you were a secret Bush lover Chris....

[@allthegearnoidea6752]

I love a nice bush

[@boxingday11]

Hope your well/ok Chris 👍🇬🇧

[@allthegearnoidea6752]

Feeling much better thanks.

Bakelite does break and it is hard to fix. Try scraping some off the inside of the cabinet and mix it with the glue to try and 'hide' the repair and cover your tracks. And if you ever need to change the ballast resistor because it is faulty or you want to reduce the heat (or asbestos!) then try a dropper capacitor. Also good practice with Dropper Mains Cord sets.... Paul Stenning has a calculator on his site. I really must do one of these....

[@allthegearnoidea6752]

Thanks Steve. I have never been really happy with repairing bakerlite unless it’s painted. I have tried sanding so bakerlite into the glue mix it works but it’s not invisible. I have tried filling with wax sticks but again it’s not perfect. I did a video on calculating dropper capacitors if you enjoy the math.

[@Steveuk405]

@@allthegearnoidea6752 I do as I am rather sad! Well as an ex BBC Transmitter Engineer I am used to it,

[@michaeldranfield7140]

Tcut is also good for cleaning Bakelite.

[@allthegearnoidea6752]

A lot of people say the new formulation is not as good as the old stuff was but haven’t yet tried it myself

[@michaeldranfield7140]

@@allthegearnoidea6752 Thats good to know then,the tin I use is over 20 years old ! T cut has no place in modern cars now they use water based paints and a clear over lacquer.

[@dougmcartin3881]

Hello Chris. Funny that I was just thinking of you yesterday. There was a guy with an old 60's Chevy pick up truck at the supermarket and I realized that you haven't been around in a while. Glad you're alive and well. I wonder if that crack by the tuning knob was caused by somebody trying to remove it with a screwdriver that didn't know the secret on how to release the knob. ATB Doug.

[@allthegearnoidea6752]

I don’t know how I missed those cracks when I bought it ooooops

[@radio-ged4626]

Sounds great, looks great. Nice job. Cracking...(sorry).😄

[@allthegearnoidea6752]

Shame about the crack I really don’t know why I didn’t spot it. Still the radio is not in a box somewhere so such is life onwards and upwards! Thanks for watching and comments regards Chris

[@mohinderkaur6671]

Nice restore complete with the RIFA bomb

[@allthegearnoidea6752]

It will give the other guy something to change in another 70 years time.

[@zx8401ztv]

Nice to see you fondling a radio again :-D It looks so nice in comparison to the pile of poo it was. You caught quite a few crappy bits before they had a chance to burn the house down lol. I would have hardwired the neutral to the chassis too, earth by another name. Thankyou for a smashing video chris :-D Don't forget to lube the brain with cups of tea. P.s David tipton has restored some nice radios also, you might like his way.

[@allthegearnoidea6752]

David Tipton does amazing work but he has more patience than me etc
