Put in the 6.8 k resistors. It turns out I only have two EL's but they went in anyway . That was after I turned it on minus valves and checked a few voltages. A bit out of range. I populated it with valves and turned it on . I had forgotten to check the bias and it started redplating in one valve. I quickly rectified that. It goes but it has a lot of hum/noise and doesn't seem very loud. Wound up it tends to crack up . I missed a ground connection on the second channel and had no vol control but I figured it out and fixed it.
I'm thinking this is all unstable power supply and I need to replace all the caps in it and maybe a few resistors . The same goes for the bias, get a new pot and a few bits.
I did some measurement of the H.T. voltages etc. They're a bit askew . The main H.T. is high and the others are low compared to what the circuit tells me. I'm going to go over it and write it all down. The P.T. is reading higher for the secondary winds than they should be.
