Hello all, I have searched, watched, and read as much info on this amp that is out there for weeks, and i am more confused than when I started. Quick story, I bought the amp as parts on order to steal the pills for a Texas star, that was a successful swap, it's initial problem as seen in 1st photo is that it burned the rf chokes off the relay..before pulling pills I used a 10uh Texas star choke across hot side of relay to bias terminal, immediately would sizzle when I turn the amp on..no rf..so i disconnected bias, preamp, output trans wire one at a time with the same results, so then I gave up and stole the pills. Since then I've rebuilt the key circuit, new relay, put a nice pair of hg's in there, I don't plan on hooking up the preamp...i also put a diode across the coil, it keys well...but where and what rf choke should I place across? What might blow the choke? The ab bias circuit maybe shorted somewhere? What should the bias cap at relay be in value? It has a .1 poly at moment, is that correct? Anyone out there with a clear pic of their black label base relay with this setup? I thank you all in advance for any input, 73's from 2 OP 095
