OK I just got my OR120 from repairs.
The schematic seems to be a 1972 wiring with some 1973 specs.
Hence the amp is most certainly from 1973.
Got a whole set of JJ Tesla tubes put in. Rifa and JJ caps and a bias-pot installed.
Serial number is 120345
Listen to my
Big Pics vintage OR 120 from 1972
Maybe someone can help you date your Orange Amplifier?
