I need to apologize to those I have not responded to in a few days.

On Thursday night my iPhone got updated and since then when I log into this site near everything is whited out and I can see nothing.
I had to wait until now to come back to work and use my iPad on  the company's WiFi.

Go to MusicParts.com, they list the schematic there.
You can buy right there on line and it will load to your computer so you can print it off.

Here's a guess as to what happened to the amp.
A quad of EL34s need 2.5 amps more of heater current then does a quad of 6l6tubes .
This means that the power transformer likely ran so hot that it shorted out and burned up in smoke.

Please report back with your findings and if you need help.
I quick way to test for a major short is to pull all the tubes out and install a 1 amp fuse.
If  that fuse blows at power up or when the amp is taken out of standby then you have a major short.
