Nice work! Are those tube sockets standard or modified in some way?
Standard modified sockets! Bottlehead ships some O-rings to put around them. No deviation there from the printed plans.
I've got a hum (60 cycle I think?) in one channel that I can "fix" by pulling up on the volume knob so I think I probably overheated something in that pot. Wiring in that area with the cable I used was very tight so I'm going to rethink that. One thing I did find is that you can use the headphone ground connection (goes from one side all the way through to the other at the base of the headphone jack) as a ground bar for other connections at that point rather than have to try and use the terminals themselves. That goes for the ground wire coming from the C4s also.
A thought - this is my first build with the Mundorf caps. Are they really that good? Prior to this I've used Sonicap or Clarity caps.
Because of the smallness of the caps (.5 and 1.5) the cost is fairly low. I'm wondering if I can build something that will allow me to switch caps in and out easily. Because of the headphone connection this would allow some very nice cap comparisons.
I used Mogami Neglex 2534 from input to pot (the green cable). It has two pair and a shield. I then used Mogami Neglex 2549 in other areas as it is one pair (blue and red cables). It's hard to use that near the volume pot - there's not much room in there.
