Hi Gang,
I received several requests recently for schematic diagrams of my homebrew
8877 amplifier. This is an amp that was described in the Bill Orr W6SAI
Handbook in several editions. I rebuilt the amp in the mid-90's to
incorporate the WARC bands, and also added QSK and electronic bias
switching.The schematics for the upgraded amp have never been published.
Recently, I upgraded the amp again, mostly in the HV power supply. The
latest schematic diagram can be downloaded from
