38-116 died the 3rd time! Guidance Please?
#34

Thanks gang, after my last blunder I figured you two would never come back!Icon_sad
I did try a pair of 6L6s out of my Scott and no joy. I will first remove the existing ones and see what happens to the B+. After that, on to the negative side as Brenda suggested. Seems something is loading it down as mentioned previously, about 3 seconds after power up the voltage seen at say the plate of a 6L6 will go up approaching 400V then the load slowly starts as the other tubes warm up and what you see are low voltages. Good spot on the 6J6 Brenda.
Mortz as for your questions, remember ladies first.
1. Yes they are, let me correct my previous posting Mortz. Too many numbers running around. Thanks
2. On the 6A8s the voltages were updated in my previous post. Apparently my tube extender was not in well. They are now more in line with just low!
3. The measurement of the B+ line right after the choke is accurately reflected in the G2 measurements on the 6L6. Low with respect to ground.


Off to the garage in the morning.
