Hi Everyone,
I'm new to posting on Aos so please treat me kindly. And I hope I have chosen the right place to post... So here goes.
As a long time fan of Radford, I recently acquired a very sad STA12.
This one had suffered more than most. Clearly in the past it had had the reservoir/smoothing cap explode. There was sticky residue and flakes of paper and foil under everything. I guess that was the start of 'someone' fixing it up and 'modifying' it. Triode connected outputs and shared cathode bias resistor, components dangling on bits of wire and so on.
Then it had clearly been dropped and the transformer chassis badly bent together with the outer frame.
Only one thing to do, a total rebuild. This is where I am to so far, the is chassis stripped, cleaned and straightened:-
I'm missing a few parts, especially an output transformer, so please look out I will be on the scrounge!
