Get inside the? single 3-1000Z? amp....and? measure the? actual? voltage? being applied.? It may well be a simple thing,? where you have it hooked? up incorrectly, and have diverted a? huge chunk of that? 39? volts? in another direction....leaving very little V left for actual? biasing purposes.? ? I suspect you have? some voltage divider action taking place some where..and quite possibly on the board itself..or a combo of? board and? external to the board.??
Since you also have a 2 x 3-1000Z amp,? you could also use the? tube from the? single? 3-1000 Amp....and stick it into the 2 hole amp.... to verify the? tube is just fine.? ( which it probably is).?
That board has? bucket loads of bias to do the job three times over.? ?
