Hi there
I would like to see if it would be possible to use a 6528 or 6528A tube. It has a pin out the same as 6080 with a much, much higher transconductance of about 37,000. http://frank.pocnet.net/sheets/077/6/6528A.pdf
The only potential problem I can see is that it draws about 5A of current, much greater than the 2.5A of the 6080.
To overcome this I am thinking of using a separate transformer to feed the heaters of the power tube. I have found a Hammond transformer with two secondaries that output 9V @ 6.67A. I would hook this up to a couple of regulated DC filament supplies, one feeding the input tube and the other the power tube. These would output the correct voltage to each tube as a DC supply.
Do you think my plan would work? Expensive, I know, but an exercise in learning.
Thanks.
