Power on! Light! Wheeee!
Check HT fuse, just to be sure, and it's blown with no valves in the amp.
Dodgy capacitor is the most likely culprit according to Foxen and sure enough there's a bit of white fluff by the vent on one of the filter caps, which means it's probably dead, and this is further borne out by a quick voltage test across the caps. Best thing at this stage is to do a 'brute force' recap, so that's more money to spend.
Bah. But learning is good.
Hi mate!
ReplyDeleteI have recently acquired one of these amps with the matching speakers.
its in not back nic, I opened it up and found some of the small caps are leaking, I have tried searching for caps of the same value but am struggling. I have never changed caps so not sure if they can be changed for different voltage values with the same uF rating? could you keep the posts coming please with details of the parts you use so I can bring the old amp back to its former glory without damaging it and learn in the process too! thank you!
