Have looked through my collection of power transformers and none have a centre tapped high voltage winding. Just to get it going to see if it suits my speakers I am wondering if I can use a bridge rectifier arranged as either:
1. a hybrid using the tube rectifier plus the 2 diodes on the pcb but fitted in reverse with the other end of the diodes (which go to connection SW1) linked to gnd at the connection for the centre tap. This is a very short link on the pcb.
2. all diodes external to the pcb with B+ tapped into the junction of R1 and C2 and gnd to the connection for the centre tap.
In both cases the heater connections would be untouched.
Here is the schematic:
Simple SE schematic
Please tell me if this is dangerous!!!!!
Thanks, sp
