Here is a montage of sounds I've dialled up on my 1939 Novachord over the last few days. This 1/4 ton beast returned to the land of the living this week, after spending 200 hours completely rebuilding her PSU chassis and repotting the supply decoupling capacitors in the generator chassis. This is an amazing design for the era featuring two active smoothing, noise cancelling, HT rails and several other conventional ones.
Number 346 has travelled all the way across the Atlantic from Seattle to the UK after Marc Doty gave me the very generous opportunity to take on and restore this amazing beast.
For those who haven't been following my restoration thread, here are her essentials:
World's first commercial polyphonic subtractive analog synth, built in 1939
1069 manufactured between 1939 and 1941
163 electronic vacuum tubes (valves)
Weighs 1/4 ton
Features full 72 note polyphony
Configurable envelope per key giving control over Attack, Decay and Sustain!
Multi stage LC based Resonant low pass "formant" filters
6 channel electromechanical vibrato
Swell and sustain pedals - with high and low octave split
Cost $1800 in 1939 or as much as 3 family cars or a house!!
Unlike Phil Cirocco's infamous rebuilt Novachord, apart from the PSU chassis, number 346 is currently running with an almost totally unrestored generator chassis containing 146 tubes and over 800 capacitors. At present all but the bottom two octaves are running albeit with some minor calibration and tuning issues - not bad for a 70 year old electronic beast!! http://www.hollowsun.com/novachord/Nova ... ontage.mp3 Novachord 346:The Huge Generator Chassis in the "Service Position"
