I bought a G36....right now i`m going over the machine. I havent had it powered up yet, but the seller (who inherited it from an uncle) did power it up - and everything seemed ok.
Sn is 62384, 2 track and 3,75/7,5 ips. Probably a mkIII
My question is:
There is no selector for mains voltage, only the fuse where the selector should be (according to the manual and photos on the net). See below...and swedish text for "högtalere").
Dont I have to move the mains wire to the 240V connections on the trafo inside - and shouldn't this be possible?
Caps seems fine and the ones I have meassured in circuit have fine values. For now I dont intent to change any caps or other components.
Motor spins freely activated by hand. For now I will leave motor as they are.

Since it is difficult to get to the transformer without taking the machine apart, I would check the power supply voltages and heater voltage to see how far off they are from what is in the service manual.
Thanks Blinker
That is a good and very convenient advice - i'll happilty srick to that.
I didnt mention, but I hope it was understood, my mains are 240V - and the G36 is rated 220V.
I'll get back with herater meaassurements.
Thx.

Serial number above 71,800 has voltage selector. Pages 63, 64, 65.
Yours looks like 62,384.
Get a 24VAC 1A transformer and rig a step-down. (20VAC a bit better.)

That also a nice solution, although Im not sure how to do that...do you have a link? By the way, our mains are 230v, not 240v.
I now powered the Revox with a variac at 220v...and it went allright.
All bulbs are dead...
Amp-meter at variac showed <0,6A, which correspond to labeled 135W/220v...right?
All functions worked, though one channel was very low and there was almost no sound from internal speaker - I will investigate all potentiometer on this.
With the variac Ill check heater voltage at 230v later to see if it within the tubes ranges.
Thanks again Torben
