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!!
