Thanks Bill I don't have a schematic of a VII but it seems rational to assume the same "type" of mod would work in it. Let me know what you end up doing.

I see no reason to wast power with an attenuator and there is a sweet spot in the final current thru the mod iron that requires a less than full rated final current to avoid saturation. It seems to me that a fine adjust here would allow power reduction for use with an amp and also enable fine tuning the final current without reducing optimum drive current when used barefoot. Just an idea. I like the ability of the DSB transmitters like the HT 37, FT101,etc to lower the output power without having to retune the final. 73, Bill, KB3DKS -----Original Message----- From: W6OM Good question, I have not restored any Viking II's or set them up to drive an amplifier but as I recall they have a pair of 6146's in the final rather than just one don't they?
