Boy, these took a very, very long time. I used the Posiedon boards setup for the MKIV voltages, and I removed the balance pot and a few other parts to allow independent tube biasing. Other than dropping some voltage by reducing the input cap, these babies are all finished. I thank all of you on here for the help you've provided. These boards are VERY stable, and super fluid in these amps. I've settled on the ECC803S new release Tung Sol for the input tube, and I'm running some gold pin E80CC's for the phase splitter. The rectifiers on these are dual 5U4's. With the dropped voltage, I'm looking at ideally being around 365VDC on the plates, and around 105ma at idle per 829b.
