The several LV supplies need to be connected to the rest of the unit so a couple of rows of screw terminals were applied also with epoxy glue. The +18V, U4, supply was built and as with the fixed 6.3V supply, the ground pin of the three-terminal regulator is biased up, in this case by 13V to make it regulate at +18V out.

This means that the power supply voltage will begin to rise as the preamp and power tubes begin to conduct and draw current from the supply. Thus, the potential for long periods of excessive power supply voltage on a cold tube is very minimal. The risk of arc-over failure on turn-on is significantly reduced!

The design of basic tube power supplies is actually very straight forward. And, if we rely on the excellent work of those who've come before us (O. H. Schade, N. H. Roberts, D. L Waidelich, H. J. Reich), we don't even need to tackle any advanced math or taxing mental gyrations to arrive at some truly excellent power supply designs.

Photograph 2: 12AU7 Tube Preamp Power Supply. I was pleased with how well it turned out, at 30 bucks it looks pretty professional with the solid gold plated jacks on the black case. A neat feature I added later on is the ability to adjust the brightness of the front LED. The yellow LED is to indicate that the tube filaments are active.
