It came straight out of the junk box. I started with a pair of Allied transformers that I picked up very cheep.
With a SS diode full wave, the voltage was a bit too low. Full wave bridge a bit too high. So I fed that into a small .22 cap to knock down the voltage a bit. The rest are bits rescued from a junk computer power supply.
I checked the voltage and ripple with a DVM and was good to go

It was not until months later, someone ask a question on another board so I hung my scope across the output. It is down right ugly. Between the transformers, the unsnubbed diodes and the small input cap. The thing rings like the bells of St. Mary .
Still using it though. Like Arlo says " we’re just wait’n for it to come around on the guitar again , that’s what we’re doing"
I ordered a proper transformer and in due time I will fix it.

In the mean time I am working on the 300b amps, putting some of Damir and Bas’s ides in the mix. More on that soon.

So who’s boards do you have?…John
