Ok, so i've been keeping my amp turned on figuring it would burn in. I haven't finished building my speakers yet but they should be done this weekend. I was noticing that one tube glows less than the other. I switched them around and the weaker tube remained weak and the strong glowing tube remained strong glowing in the different four pin socket. So does this mean i have a bad tube?
My DC voltage readings are incorrect in a couple places. First across the 3.3 uF film capacitor at terminals 1 and 5. Term. 1 is correct with a 419mv reading but Term. 5 is reading 0 where it should be 60.
Next, my .1 uF 630V film cap. is reading 51.5 mv at term. 1 where that should be 0 and correct at term. 14.
Terminal 16 should read 60 and i'm getting .4mV and down to 0.
My four pin sockets:
A1- .3 should be 60 A4- 0 should be 60; C3- 49.4 should be 0
Everything else checked out fine!
