Looking around the web tonight for 6m amp designs using the GI-7B and i came
across this schematic...
http://yu1aw.ba-karlsruhe.de/shema%201xGI7B%202m&6mmod.gif
I understand the schematic except for one thing.. At the top middle where the
connection for +Va is shown it comes down to a second connection point and then
it shows a ground to the left and a connection to what appears to be a large
cap to the right, i assume its a capacitor as that makes the most sense but
these foreign guys use different symbols for stuff sometimes. Why is that
second connection point with the (o) and a ground connection to each side
there? Seems to be a dead short for the HV.
He also doesn't mention what the value of this capacitor labeled as Ca should
be. I know, this could be a stupid NOOBIE question but these foreign designs
are always so sparse on the information and there is hardly any explanation,
etc..
I like his design overall though, looks fairly simple, thinking i could do my
SB-200 conversion so its a 6m/2m amp in one. If anyone has built one of these
please pass along any info you have! A picture says ten thousand words for me.

Scott
