AWA battery eliminator issue
#2

Hi Rob,

I hear you re the 70 year old eyes. Is the B section full wave w/ center tap, half wave or bridge? Can you post the schematic?


Is this the AWA (Antique Wireless Association) W3NLB-N6GA PCB?

If so, did you install 4 diodes to make a bridge? If so, did you connect 3 wires from the transformer (connect the center tap to B-)? If you did, that is the issue. Depending on the secondary voltage of the transformer and the desired output voltage, either remove the center tap connection or the 2 diodes that are going from the B- / Center tap connection to the 2 legs of the transformer secondary.



Hope this helps.
