Default Re: Ferguson 621U - help needed

Need a bit more help with this set please.

Radio was fine on all bands for about 1 hour when it started to crackle and pop. Coming and going at first, but then quite loud irrespective of volume control setting with stations still audible. Then AM stations became inaudible followed by the FM stations, the crackles persisted. When subsequently switched on from cold the crackle is still there, but stations can again be heard. I switched off at this point. Tried a spare UL84 with same result. I'm assuming that the problem is in the output stage, but am unsure what to check/replace next. Any assistance welcome.

Thanks .. Andy.
