Hello all! Here's one for the re-cappers out there:
I recently acuired a revox g36 mkIII (tubes, 1/4" 2tk, 15ips!). Initial recording tests were very reassuring, however I've noticed that it lays down a little hum (perhaps 60hz?) when recording (not heard when playing back tapes from other machines) so I was wondering after seeing pictures of someone else's mod
http://home.megapass.co.kr/~pcaudio/mod-revox%20g36.htm
is there really anything to be gained from re-capping the part of the power supply that feeds the DC rails to the audio circuits?
Also, the pics on that link show tubes pulled - like the main amps for the internal speaker (which I won't use anyway) In general terms can you just yank 'em and power up without hurting anything? A good power-saving mod there I suppose.
I have the service manual (with schematics) so we're not totally in the dark - the general idea is to shine this one up sensibly as a processing device for mixes. Any input is greatly appreciated. Thanks!
Frank
