SLO-50 clone 100hz hum on OD channel?

[Spenzer Lee Horton]

well ive completely rebuilt the power supply with new caps and UF5408, voltages look good and can hear hiss on output but now no ouput?
so something is going on with the main pcb and its seems to be around V1 where there is a problem.
I'll inject a signal and test to see where its gone wrong.
Ideally i want to move the fx loop to after the masters and before Phase inverter.

Well V1 didn’t last long!!

Seemed to be dodgy valve that had messed it all up, changed tubes and sounds much better now after rebuild of psu and cap change.

Vacuum leak! Glass cracked somewhere? Was that Psvane tube brand new?

 

[Spenzer Lee Horton]

Yes it’s was psvane tube, won’t be buying them again!! Think they caused all the problems!!

A few more thoughts on this SLO-50, wanted to try and move the fx loop to after masters and before the PI.
Any problems I should worry about?
