I'm back... I had good intentions to post as the build progressed. The w/e I had planned on knocking this build out was, of course, the blizzard no electricity w/e... then a really busy week, 3 gigs.. BUT, I did knock the WetMaster out and take pictures this past Friday 2/19. AND, as promised, the WetMaster was used at the Cottage Lounge jam that night!

Here's some pics from the build. Below is a pick of the rectifier fit onto a terminal strip. The black disk is a thermistor/in rush limiter.. It prevents the 1st filter cap from getting slammed all at once with current when turning the unit on.

Here it is installed in the chassis:

Terminal strips installed:

That's the power section/filter caps on the left.. The black things are filter caps.. The white block thing mixed in with them is the resistor that biases the 6V6 that drives the reverb tank. The preamp circuits are on the right.. Note the brown and silver Russian military surplus PIO capacitors..

And the, except for more tweeking, finished product:

The unit sounds good, but it's not perfect.. As with the other two units I've put together, it needs to be tamed down some. Too much reverb too soon on the dial. There's also more hum than I'd like. I'll get those issues figured out over the next few days.

I'm glad somebody out there knows all this stuff. I'm sure I'd blow myself up if I tried messing with this stuff. Very cool. Please keep us posted on your latest. :)

Well all right then! For now the WetMaster is done. In an effort to reduce the hum the WM was putting out at the jam, I moved the earth ground from the AC plug a few more inches away from the power supply star ground. I also found one of the RCA jack bolts was loose and tightened it.. Moved some wires around a little and tightened down the input and output jacks (they were a little loose too). And she's as quiet as a mouse now. Still too much reverb too soon on the dial, but I'm going to leave it as is for now. The reverb sounds great! On to my next project this w/e!
