Hi Guys
Bush 6674 ( PT92), like someone else on the forum I've downloaded the pdf "service" manual for the PT92 chassis, and no circuitry of the Line stage.
So far PSU shutting down due to shorted line output transistor.
Changed the device and supplies up and reduced horizontal o/p with bowed verticals. B+ 176V
Looking for VAP1 to adjust the voltage I moved VAP2 which looks like the level adjust to the optocoupler and lost the BYW36 ( DD08), and I think its RD38, vapourised.
The cct digram of the PSU shows B+ as either 115v or 145 V, can I assume its 145 V ??. Pot VAP1 is not fitted ,2 SMD resistors on the under side.
VAP2 has very little effect on the B+.
Not working on this chassis before any hints would be gratefully received.

Many Thanks
Richard
