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.
