Re: Help needed with Bush TR82-CL.
The original transistor models were the TR82B and C, which mean more or less brass and chrome, with attendant detail changes such as lettering colours. They're electronically identical. The CL add Luxembourg, as was the fashion then, and the Mk2 "upgrades" to AF117s.

Re: Help needed with Bush TR82-CL.
You'll find they qualify as "Modern Technology" here, kept distinct from the vintage stuff. As far as I know, despite appearances, nothing is interchangeable. They do have a few admirers though.

Re: Help needed with Bush TR82-CL.
Each to their own regarding the reproductions.
A few other questions regarding this radio. (1) Why does it use high voltage capacitors when the supply voltage is only 9 volts ? (2) Would changing the RF/IF Transistors from the standard ones knock the alignment out ? Cheers

2) Probably not enough to notice regarding the IF transistors. The mixer/oscillator will be more critical since this produces the IF frequency.

Re: Help needed with Bush TR82-CL.
One more question regarding this radio (for the time being)
I'm sure the answer to this is lurking somewhere on the forum, But whats the best way to go about cleaning the case and buffing it up ?

Re: Help needed with Bush TR82-CL.
Give it a good clean with something such as CIF kitchen cleaner then when dry use a mild abrasive polish such as T CUT or metal polish wadding to finish off polish with a dry cloth.
Be very careful of anything that is printed such as lettering etc. I can't believe how many versions of the TR82 were produced especially if you take cosmetic changes into account. I have a TR82 with three buttons on the top. One is dedicated to 208 the old radio Luxembourg frequency. They used to turn up at the tip in regular numbers in the 80's. I used to pull off the good examples. The PP9 lasted forever as it did in many early transistor radios. Happy Days. John. |

Cheers for the cleaning tips john. Apparently there was a three band version that had a ''trawler'' band whatever that is. Currently running mine on 6 X AA batteries, But plan to add a socket in place of the external aerial socket so i can run it from a mains adaptor. Jay

Re: Help needed with Bush TR82-CL.
Jay, take a look at member Robert Darwents GOUHF ,website, www.wavesintheair.co.uk , he goes into great detail about the history of every one of these iconic models , but be careful if you get hooked you will end up with loads of them ! don`t ask me how I know ! The first one the MB60 valve model is my favourite sounding model , not that rare but hard to find with its original and unique mains plug. Then there are the rare export models including the very rare etr82 hybrid (valve and transistor) radio . i could go on , hope this is of some help, regards, Tim.

Re: Help needed with Bush TR82-CL.
Managed to get the chassis out of the case, A string round the dial is a very effective way of removing it
The top two chassis mounting points need work, Apart from cleaning the band switch is there any other work i should do whilst i have the radio stripped down ? Also i plan on giving the case a good wash in the sink, Is it best to remove the tuning scale before washing it ?

Re: Help needed with Bush TR82-CL.
Think i'll forget the sink idea and use kitchen cleaner as suggested above

Re: Help needed with Bush TR82-CL.
I would suggest leaving the dial if it is stuck well , try and keep strong detergent away from it , I normally give it a gentle wipe , Mick.

Have a discreet mod in mind, This involves removing the aerial socket and replacing it with a power socket so the radio can be run from an external 9 volt supply, I'll also sneak in a voltage regulator too. Cheers Jay

Re: Help needed with Bush TR82-CL.
I would stick to using a 6 AA cell battery holder. A mains power supply of 9V DC on these receiver will usually result in a lot of mains derived interference. You would lose the benefit of portability, and originallity.

Re: Help needed with Bush TR82-CL.
Looking for some tips on how to repair the chassis mounting points, Epoxy seems to be the most common method according to what i've read. But i was thinking of using some self tapping screws to hold the clips in place, Anybody tried doing this ?
This radio kinda baffles me a bit. It seems to be a lot bigger than it had to be given the time period it was manufactured in, And point to point wiring when PCB Were becoming common placed, Its like bush took the valves out their earlier set and stuck transistors in and left it at that, And what is the hole next to the volume control? Left over from the valve chassis ?
