I don't have my design notes here, so its from memory.1) A 5687 gain stage, as I recall, a 211 ohm grid stopper
2) 2 uF coupling cap
3) Altec 1509 15K to 600 ohm step down trannie
4) Absolute phase switching, DPDT swiches, On- On
5) Daven 600 to 600 ohm bridged T attenuators ( constant impedance )
6) Biamp L/C line level crossovers at 12 dB octave, used either vintage UTC VIC or HVC - series adjustable inductors, and set crossover for about 400 Hz for RCA field coils.
7) Three sets of RCA output jacks, Full Range Out ( off of the 1509 trannie secondary ). Low Out and High Out.
Thats all there was to it . Kimber Kable TCSS wire, multiple paralleled runs on grounds and B + es. Wonder solder. Go for it.
