RE: WE91 question

if I understand your question, the center tap of the magnequest PGP 8.1 PS can be configured several ways..

For a 2A3, 45, or other 2.5V filament connect 4S to 5S and connect 4F to 5F for a 2.5V 2.5A filament supply. Connect one end of the tube filament to 4S and 5S, connect the other end of the filament to 4F and 5F.

For a 300B first connect 4F to 5S, and then connect one end of the tube filament to 4S and the other end to 5F for a 5V
1.25A filament supply
