Bush TR 82C repair advice wanted

[ducatiguzzi]

Success with the Bush! :-)

I exchanged the audio amp transistors starting the TR4 as advised but no difference, I then replaced the TR4 then swapped out TR5 with an AC128 and the hissing is now hardly discernible. I'm not going to pursue it any further given the low level hiss on minimum volume. I see the MKII service manual states a modification from the OC71 to a OC81D for this transistor

I have my K7000 injector/tracer kit along with bits and pieces to finish it but havent built it yet but I'm sure it will come in useful, maybe even for fault finding the Hacker, I'm sue it wont be as pretty as Yorkie's but should do the job. I was thinking or incorporating the buffer caps, resistors and diode for the probes within the board and use standard Fluke probes (I have a spare set)

I've joined the Hacker group on Yahoo and got a service manual, thanks for the tip off Mark

Obviously I couldn't have got the Bush there without all your help, you all certainly got me on the learning curve, many thanks!!

Next challenge, get the Hacker working
