    NPC for AM Transformer radios is HERE... Tubed, Solid State, etc. ANY high level TX

    You really need a scope to set up. You gotta be able to see the negative peaks

    I put it in my 29 yesterday in combo with the J36 mod. I ended up with a about 33 ohm resistor. 3, 100ohm, 1W. Half watt resistors got hot! I now wanna try the LM317 supply

    The trouble is all the components for the supply are on the main board but the transformer, so it's hard to tell which components are part of the supply circuit and which aren't. I know the pass transistor and it checks fine.

    No luck with the links but thanks anyway. I shorted out a transistor, a "A200Y", by accident. I know it's a PNP cause I do have a schematic for a CBS 1000 and one is used in it but not in the power supply. I tried 2 other pNp's I had with no luck. I can't find any info on the A200y to verify...

    I am in need of a schematic for a cbs500. The power supply section crapped out. Thanks!
