lol It was 101 here in AZ today not too bad seems like it's cooling off now no more 115+ hopefully. Only 94 in my garage much more user friendly then the 107-110 it was a month ago.
Well I cleaned all the tube sockets again, and douched the bandswitch with deoxit. I ran it without any tubes or dial light and the PT never not hotter then 95 (it's 94 in the garage) so I think thats a good thing and it was plugged into the wall ~123-125vac. The amp meter I had in line showed .85mA being pulled.
I put the tubes and dial lamp back in and it is pulling 309mA (according to riders it should be pulling 40w, or 348mA) at 115vac running off my variac, and the PT is at 105 and its been running for about 15 minutes now. I'll leave it run awhile longer and see how it does.
I did notice that the 84 tube socket was pretty lose (tube pulled out real easy) so I tightened up the connectors. Also the DC from the cathode of the 84 (pin4) tube is low at 260vdc, schematic calls for 290vdc.
