JLM AUDIO

I don't think it uses a pump charge, here's the schem : http://www.mentol.dk/diy/upload/DIY_9k_preamp.pdf Page 5.

The power transformer is a 50 VA transformer.

That should be able to handle it right? Using this power supply but with a 25-0-25 transformer and an LM7824 instead of 7818, and left out the 7918 as well

Yea it's a heatsinked LM317

Also, the search function for the forum doesn't allow me to search "go between"

Hey, I'm having some trouble with my FET DIs. Everything with the Go Betweens works fine, but when I add the FET DI I lose 6 volts on my 48V rail, and with a 4 channel pre I'm ending up around 28V or so, did I do something wrong?
