Default Re: Bush AC34, no sound.

First, make sure that the valves are in the right sockets. Starting at the mains socket at the right and facing towards you...

The first two are the UY41 and the UL41. The UY41 is Behind the UL41 with the mains socket towards you.
The next one is the UBC41.
Then a UF41.
Then, Behind the first IFT is the UCF42.

If there are no volts on the Anode of the UL41 - Pin 2. - then either the wiring is faulty, the transformer is faulty (and now possibly the UL41 too!) or there are no volts coming from the rectifier. If there are volts on Pin 5 and not Pin 2, then you may well have a problem.

Cheers,

Steve P.
