Sweet work, Vixr. I need to learn that sort of neatness with wiring and placement.
The power amplifier is finally finished, after today's addition of the buffer circuits. No more modifications are in line.
Now, there are a total of 8 relays that power on the amplifier/output. The yellow LED indicates that the buffers are on, the green super-brights indicate that the amplifiers are on, and the red LEDs indicate stand-by (twin TREAD power supplies creating a +/-12V supply). High-frequencies are notably improved with the buffers in place. Two LM4562NAs are used as buffers. Yeah... there's no room left in this sucker.
