Don't usually like P2P unless I'm in one of those moods The advantages of using it for prototyping are obviously there though!

When I first started out, I liked PCB's, but nowadays I only like them for PSU's. All my signal and tube stuff is p2p. If I had the time I'd try my hand at etching some though.

If you can successfully solder onto the heads of nails, then you have passed the trial by fire! It's a lot harder than one might think.

Ditto that.

Really nice amp, I can't help wondering one thing though, how does it sound?

to burgunder,
i think this solid based amp is good sound,它的音色在一些细节的表现上甚至比音频专用的高保真opamp还要好.

to .Sup,
thank you for the nice words,i will do that.
i have a photo album LINK i will keep it updated.

I built my first amp P2P, which was the SOHA. After that, I built the Bijou with PC boards, CK2III PC board, Beta 22 PC board. I then got into Stats and got a new pair of ESP 950's for Christmas this past year. Decided to get back to P2P by building one of the only DIY stat amps around, the KGSS. Some thought I was crazy for doing a KGSS P2P, instead of shelling out the $110 bucks for the PC boards. I wanted a challenge, though, and the KGSS P2P build was great fun. The blank PC boards I got from Mouser worked great and I finished it last month. Only had a few minor issues which Kevin Gilmore was great in helping me out. To me, if u have the time, P2P is very challenging, and does, as others have stated, take a good deal of patience. It's also very rewarding to see the finished project. I'm not against PC board builds, as I don't think I would have ever attempted to build my 3 channel B22 P2P. However, if a I had it to do over again, I'd probably opt to build my CK2III P2P. Oh, one other reason I decided to do the KGSS P2P, was the PC board amps I built weren't taking me too long, and I wanted something that would keep me busy longer and keep me from wanting to build another amp every couple of months. Kinda gets expensive, but hey, that's what's great about this hobby! A P2P build will take more time, and was very good at keeping me busy for a while. Tommy.

Nice work!

I've built some PCB gear, but really prefer P2P. I think that's from getting into hi-fi DIY by way of restoring old tube radios. Those are all P2P and I got used to the layouts, construction and techniques.

If anyone is looking to learn P2P, I highly recommend picking up an old "All American 5" type AM radio off eBay for $10-$20, then restoring it. Parts are $20-$40 and radio tubes aren't priced ridiculously. You'll learn a lot and see that it isn't that hard.

One drawback is tha P2P isn't always appreciated by people. They have come to expect neatly laid out PCBs. If you have wires running around - any at all - it gets referred to as a "rat's nest" and is regarded as sloppy work. It's too bad they haven't been able to personally experience a "rat's nest" Atwater-Kent neutrodyne that's been working for 80 years. Using a very proper star ground especially tends to set people off. I hope P2P isn't a dying art - it is the best way to work with tubes. They can always be simply repaired and maintained.
