BUSH TR82DAB

[Old Sparky]

As a follow-up to previous posts, I refitted the drive cords (not too difficult!), tested the radio on all bands, and, whilst it worked OK, the replacement SMD 3.3v regulator IC ran quite warm after about 30 minutes. Because of this I soldered a piece of tinplate about 0.75" long x 0.6" wide to the PCB 'heatsink' to extend the surface area of the latter, being careful to keep it clear of the adjacent SMD IC, whose tab is at 0v, whilst that of the regulator is at +3.3v. I bent the added tinplate downwards and tested the radio again on all bands. It has now been run several times for an hour or more at a time with no sign of any distress. The only other problem is a (very)slight mains hum present when the radio is switched off, which seems to be common with these sets. I may well leave that as it's not intrusive, and the radio can (should?) always be switched off at the wall when not in use.

One of my sons told me my Christmas present was 'in the mail' - and it was! It arrived this morning and guess what, its a Bush TR82DAB!

So, should I replace that voltage regulator as a preventative measure or wait and see how it goes?

Now I've had my first play with DAB - only picked up two stations so I reserve judgement until I've more experience with it.

John,

The TR82DAB I bought back in 2005 has been in daily use (at least a hour every day for BBC World Service, BBC 4 Extra, BBC 5 SX) and so far I've not had a problem with it.

So my advice would be to see how it goes and only change the regulator and electrolytics if it becomes necessary.

Thanks Robert - will do. It doesn't look like I'll be using it much for DAB reception - it looks like all but two stations over here are DAB+. Still, it works fine on FM and AM.

Just a short follow up on the Bush set. I've been using it in the workshop and while the sound quality is fine on FM and DAB, on AM there is a distinct loss at the high end - treble is very poor. I checked with a number of my other older sets and the Bush is definitely below par when it comes to the audio top end on AM. I don't know if other folks have had similar experience. It's not bad enough to stop me using it but it's a shame nonetheless.

Cheers, John
