As you may or may not know, I have the original Ultravalve amp proto-type. Dr. Dean Kayser was also very nice to me and built me a FET Valve preamp, without any frills. It has a 6 position line level selector switch, a volume control, a balance control and the left over remnants of the Dynaco Pat-5 speaker selector switch (it works, but I don't use it). I have just finished a new, wood faceplate, that replaces the old Dyna plate (it just had too many holes and an ugly factor) so I made a new oak faceplate.

I've also dressed up the Ultravalve a wee bit.

This is my garage system, powering a pair of Pioneer
SP-BS42-LR SP-BS22-LRspeakers.
