Gents, I have a Vectronics VEC-912 SS amp, which I believe is the same as the Ameritron ALS500. I am seeking the schematic for the 10/12m mod to add in the AUX position. I have googled and all I found were install instructions. There seems to be 2 inductors and 4 caps on a small PWB. Does anyone have the schematic? Thanks much and 73, Tommy W7RV
