Re: Tektronix 585A Voltage Diagnoses Problem edited


 

Albert,

I checked the voltages and here is what I measured after a 10 minute warm up;

Tube Pin Voltage

V609 7 -107.4

V624 6 +1.5
7 -107.6
2 -104.0

V634 6 -38.0
7 and 2 -87.0
1 -87.1
4 -2.4

V627 9 +69.0
V637 same
V647 same


As you mentioned in you previous reply I found that pins 6 and 7 of V624 vary widely. I changed that 12AX7 with no change.

Thanks Again,

Randy
