Very clean, nicely done Jeff... Are you happy with the MCaps? I've used them in some speaker work and found them nice-fast, but sometimes missing a bit of detail on the high end.
Thanks, guys!
@thompsontechs, I'm afraid I'm a bit of a capacitor-sound skeptic (at least as far as coupling/decoupling caps go). I was going with a blue colour scheme for the amp sections (thus the Nichicon KAs and TDK films), but the blue ClarityCaps are absolutely monstrous -- so I settled on a different colour scheme for the I/O section and chose some decent caps which matched the white/red of the RCA sockets.
I have collected a nice cross-section of available caps to do some A:B testing in a speaker cross-over, but haven't gotten around to it yet.
PS: before some of you jump all over me for selecting components for colour, let me remind you that this is my amp. 🙂

Very Nice DIY Jeff !!!
p.s. to my taste - the NEUTRIK connector on the front panel is just a bit missing

I know there is a difference, but I think many get caught up in it the way they do cables and such.
Choosing for color will drive some bonkers, but as you said, it's your amplifier.
I must admit though I have never seen that approach to an amplifier build... 😀
Cheers!
Nice looking amp JeffYoung! Thanks for sharing. If you do choose to try some other coupling caps I don't think you will regret it. I used the same Mundorf "MCaps" on my B1, and replacing them with Clarity Cap CSA's on the output and Mundorf Supremes on the input made a very noticeable difference. If your amp has gain I suspect you would get even more out of the input cap change than I did on the B1.
for saying it out loud!IMHO, red components would be most appropriate on Papa's green B1K Christmas boards. It only makes sense.
Yep.
Grooving the faceplate:
Turning the volume knob insert from Richlite (check out the cool Bakelite knobs on my 1953 Clausing lathe):
Boring the hole for the volume knob insert (this is a 1955 Bridgeport, although the boring head is "modern"):
Tapping holes for the "button board":
Cheers,
Jeff.

Beautiful craftsmanship Jeff. What many people don't recognize is that you could have paid for a commercial HPA-1 with the amount of hours you must have put into this. It's not about the having, it's about the doing that drives you. Cheers!
