Thanks, it was a great project. Actually built that for my grandfather.

That rules man! How does he dig it?

At first I was kind of wondering about the dual tonestack, but then I realized it's actually great, for example if you're using two vastly different speakers to EQ them pretty respectively. So awesome

he loves it. The idea for dual everything is that he has one ear that is really close to being deaf and one that is okay so he needs asymmetric volume and EQ. It was stupid loud in headphone, almost 2 loud. Probably could easily run as a stereo amp if you wanted it to.

That rules man. The whole thing is so well thought out.

thanks! fun project for a family member. He still rocks it to this day. Not a lot of cork sniffing going on either. Just simple stuff in there.

This is amazingly cool, Nick, I love it! *blown away*

Have you ever built a simple stereo tube amp for audio?

Cool forum you've got here too, buddy!

No I have not but I certainly could. There are also lots of very nice kits (Dynaco stuff from 35W stereos up to 100-200W monoblocks)

You wanna come up to Michigan and work your amp crafting magic in restoring my old Hi-Fi stereo cab? :P

Looks slick. Did you leave the top exposed when you gave it to your grandad?

yea as is, no shell.

I love how beefy it is.. it's seriously cool... your grampa must think it's so cool that his grandson can make world class audio gear like that. Bet it sounds as amazing as it looks too..

I'd love to have an amp like that for music, I just use a simple stereo setup for everything anyway. I'll check out those kits but I bet they aren't as cool as what you made..

ahah thanks man. I kinda overspecced it. That PT could put out like 10-15W of power and I was only asking like 1W in Class A per side. Heavy shit tho haha. It has dual EQs in that one since he is partially deaf in 1 ear. Thus he could have independent control of each side of the stereo image.
