Let's build Krmathis a Beta22!

post #1 of 590
Thread Starter 


So, what is this thread about. Let's show how powerful the DIY community is here on Head-fi. This would be a first, on Head-fi but need not be the last time. Why, Krmathis? Why not. If he is interested, then we would contribute either fabrication time, parts, or shipping funds. Does he know about it? Not until now. I have volunteered to build one full amplifier, labour only. Anyone else in? Instead of a group buy, this would be a group build. Imagine how much fun as we give our details of the build on this thread! Remember, this is pro bono. If you can only provide moral support, then Thank You too!

Update: The decision has been made that this will be a 4-channel balanced build.

Wow, I think this is a great idea! Definitely well deserved.

I can't afford to pitch any funds or parts right now, but I'd sure enjoy the opportunity to build up a b22! I can volunteer time to populate and test a complete amp, but I'm no good at the case work.

What a fabolous idea!! Very generous. Unfortunately, I have never touched a solder iron, but since I live only about 2 hours drive from Krmathis, I will happily volunteer for both moral and listening support
Also, I would be happy to contribute to the parts funding.

Wow, now I am getting a bit humbled! :blush:
I really love this community (as you probably have guessed), and if this goes through I will be forever grateful.

I have had my eyes on the B22 for months, as it seems like a really nice and versatile amplifier. I even contacted 'naamanf' about the possibility to get him to build me one. Which he sadly would not be able to...
...and now this.

The creator of the Beta22, has generously volunteered to provide us with technical support. He did not know about this thread until just now.

I will offer guidance, support, and if needed, hands-on debug and testing to make sure that this build will be as good as it could be. I don't know how the logistics would work out, but if any builders would be in the San Francisco Bay Area then we could have a solder-slinging mini-meet!

Whenever you guys get rolling let me know and I'll see what I can provide. There's a chance I could donate a trafo for the project.

Interesting concept

I'll happily PayPal a few bucks towards parts if a 'fund' is set up......

Hmm, perhaps someone needs to get a BOM and budget together so we have a target?

Edit: I'd be willing to coordinate and put this together on Google Docs or such, if it's deemed a good idea.

Another Norwegian Headfier, ingmarwa, is getting a beta22 soon, so if you want to audition it, krmathis, you should PM him.

I know I have the capacitors for 2 boards lying around that Ill be willing to donate. I can also help out designing custom panels and maybe partially fund them as well. Since he is in europe I think Hifi2000 case/s are a wise choice. Im guessing we are talking about a balanced B22?
post #12 of 590
Is there a Paypal account we can donate to? I don't have any experience building and I don't have any parts to donate... but I can donate some funds. I enjoy Krmathis' posts and would like to learn from the group build thread.
post #13 of 590
hmm, i know nothing about diy, but i will be there for support. I shall sacrifice a pair of ibuds for this project (my excuse to burn them and see what happens )
post #14 of 590
My funds are pretty well tied up in a SOHA II proto-build, but I would be more than happy to donate some bench time.

This is truly a beautiful Idea. I hope it is successful and the first of many such community efforts.

I'll donate cash to the project. Might be able to help with a case if needed. Let me know.
