This is a monster 8877 amplifier which includes many commercial features such as grid trip, step start, etc. This design I think is common. The power supply is on casters and developes 4000VDC at 1.5 amps. You can run this amp in RTTY mode all day and nothing will get hot. The build out for a home-brew is nicely done. I have included much detail. I do not have the PC board layouts. After becoming intimate with this amp I would not recommend the current PC layout. If someone is interested in building this amp and doing the boards E-mail me and I would work with you on the new build.
