Here's the schematic for the Stereo 18 watt power amp. I don't have a layout diagram since this thing was wired point to point. You would have to look at the pictures on page one if you wanted to copy my layout.

Parts in blue are just higher wattage parts.

Finding a power transformer for this project my be tough. I happened to stumble on a 4 x EL84 stand up power tranny. AC30 power transformers would work. The voltages must be lower than a typical Fender type power transformer. This one had 280-0-280 for the high voltage winding.
