FWIW, I received a message from Imagineering that the order is in production and will be shipped before May 11.
FYI, I'm going to make a mention on a couple of bigger forums about having these, so if anyone is on the fence about wanting a pair of these boards, speak up. There are only 6 pair left, as I'm holding a pair for Endspec and Dan, in case they want them. Anyone can back out if they want. I'm in no hurry to get rid of these, and I feel certain I can unload as many as I need to elsewhere, if it comes down to it. Would just rather do it here first.
My short term plan is to try to help develop a definitive parts list. Not recommendations for brand names, etc., just components, their values, and their spacing or size limits on the board. I've been working on it some with the limited info I have. I used the schematic posted on Mr. Millett's site to come up with a rough idea of what we need.
I would love input from experienced builders to advise on what type of component to use for each spot on the board, and why. For example, should we use a really nice quality .22uf cap for C2 and C3, or is it just as well to use some generic part. That kind of thing.
On each pcb there will be 24 or 25 resistors, depending if you use NFB. 13 capacitors, 7 electrolytics and 6 films. Also the phase splitter transformer and a pair of 6SN7s and the rectifier tube. I read a short thread on DIYAudio.com and some guys mentioned having problems getting their holes spaced correctly in their chassis for alignment with the pcb mounted tubes. This can make a real hack job of a nice chassis, but I know from experience it's not that difficult if you plan ahead, measure properly, and then cut properly. If you do pcb mount the tube sockets, then you have to do a decent job of aligning with the cutouts you make in the chassis. As a last resort, you could chassis mount all the tubes and run wiring to the pcb, or if you goof up, buy some of these;
