Maybe its because its late at night and my brain isn't working...
Looking at this schematic for converting an SB-200 to a two band amp using the
GI-7B for 2m and 6m.

Ok bottom right, the bias circuitry, it shows a connection point for -Va. Some
designs show this connection and some don't, which leads to the confusion of
where does this actually connect to, or to be more specific if converting a
SB-200 using this design and adding a filament transformer for the GI-7B where
is the best place to make this -Va connection?
Another thing, sadly i saw the posts of Tony's passing. Will someone continue
the production of the Bias board? Looks like a really good solution to build
into this conversion.
You will have to forgive the dumb questions, first time working on a conversion
of this type, i have rebuilt and repaired HF amps before, but nothing of this
nature. Should be fun though!!
