[HAM] Percussion & Matching Transformer

[Jordan Kersten]

Does anyone know exactly what the difference between a B2 and B3 matching transformer is?  I know that the B3's have some sort of a resistor that has to do with percussion volume, and the B2's wouldn't have this.  Are the transformers themselves the same? Can you modify a B2's transformer with the percussion circuitry it needs? Or would you have to replace the B2 transformer with a B3-style one?  I am converting a B2 to a B3.  I now have tracked down the plate with percussion tabs, the AO-28 preamp, smooth drawbars and even a newer style vibrato line box.  I have herd that they have different transformers.  Can anyone comment on this?
