Need a schematic for the Tweaker 88

[Jessabert]

Anybody please have a link to a schematic for the Tweaker 88. I want to install EL34's into this amp but will have to swap out the power transformer. By chance, has anyone tried this??..I really think this amp would sound killer as a 50 watt EL34 head , at least for my purpose's...

Many thanks in advance.
