Hi, I have not seen much mention of this. Has anyone swapped the rectifier tube for diodes in a PAS? If so, how did you do it specifically? And what do you think of it performance/sound wise?
Thanks!
Thanks!

Yes, it's perfectly doable.Kinski wrote:Hi, I have not seen much mention of this. Has anyone swapped the rectifier tube for diodes in a PAS? If so, how did you do it specifically? And what do you think of it performance/sound wise?

3 and 4 is filament. Let it be as you will remove the 12x4. And they don't connect to the power switch !!!Kinski wrote:Hi, thanks so much for your help. Im a bit confused though. I'd be very grateful if you would help me out here.
The 12x4 socket is wired:
1: red/white lead from the transformer
2: nothing
3: To caps/diodes that used to be the selenium rectifier. Also to power switch.
4: To caps/diodes that used to be the selenium rectifier Also to power switch.
5: nothing
6: red/white lead from the transformer
7: to (newly replaced) CAN filter capacitors.
I get how to wire the two red/white transformer leads to the diodes, but what about the rest of the wires?
No there is no such reason.Kinski wrote:My mistake! Those leads from 3/4 go to the indicator LED, not the on/off switch!
Is there any reason I can't just remove the 12x4 and solder the un4007 diodes direct to the socket pins?
419 is no problem.Kinski wrote:All good! Installed the thermistor and a fuse. Dropped the voltages perfectly. If anything, the voltage readings are a volt or 2 low now. Perfect! Thanks so much for your help!
