100+ Head-Fier
I've been thinking about trying out the Darkvoice 336, and looking at the schematic I've found that I have most, if not all, of the parts and tubes needed to build one. There's also an article on TubeCAD with some suggestions for mods that I've looked at, but I'm starting with figuring out the PSU.
I have a 120v/400mA transformer that should give me about 150 volts rectified. I don't have a choke so I'll have to go with big caps for my filtering, I'm thinking a bridge rectifier and then 330uF - 20R/5W - 470uF - 20R/5W - 470uF. I also have a couple of huge 820uF/250v caps but they're probably a bit overkill for this circuit. The schematic I found shows the amp circuit, but the power supply isn't included so I wondered if anyone knows the size of the filter caps in the DV?
