Revox G36

1963 saw production start of the famous Revox G36. It was sold to the UK market under the name "Revox 736". The famous G36 was a mono/stereo machine with stacked erase heads, separate recording heads, separate replay heads, six audio pre-amplifiers and a push/pull power amplifier which fed the built in speaker (mono). Tape speeds of 3¾ and 7½ ips are obtained by pole-changing the synchronous Papst capstan motor. Two-track and four-track models were available, both fully stereo, recording to the latest C.C.I.R. (DIN 45113) eq. Tape spools up to 10½".

I recently (02/2016) spoke to Simon in Australia who showed me some pictures of a late model G36 fully converted to solid state in 1976 by an engineer at ABC (Dennis) using parts from an A77!
