Can anyone email a schematic of this transmitter to me? The one on BAMA is the non-B version, and I don't know if they are different. I picked one up at a local estate sale and someone has installed the wrong (?) caps for the HV supply. I believe it requires two 125uf at 450 volt caps (they installed four 1uf 1000 volt caps that leaked).
They also snapped off the top of the VFO tube then powered it up. The transmitter looks to be in good shape, but who knows what hidden damage there might be.
If anyone has a complete manual they can part with, please PM. Thanks. John. |

Except for the loading cap arrangement and the number of crystal sockets I think they are identical.
The 100 had 4 crystal sockets vs 1 for the 100B.
The 100 has a course loading and fine loading control which was made up of a 50 pf variable capacitor and switched fixed capacitors. The 100B replaced this with a 3 section variable capacitor. |
