Default Re: Very odd fault with Dynatron Radiogram

Just re-read your 1st post, and other posts, so just to recap, if you don’t mind.
It runs on “isolated mains” at customer. Could you clarify please.
You removed chassis, still on its wooden plinth? Or did I misunderstand!
So at your workshop - it works ok - even on different mains - the difference is:
Not in original cabinet; not original speakers; not on same mains - voltage / form factor?
I tend to think the problem is in the preamp stage.
It’s an interesting fault and I will be interested know the outcome.
Cheers
John
