Post pics of your builds.... - Page 212

Completely defoamed HD650's. I really want a pair of RS-1's again, but I seem to keep spending money on amp projects, haha.

I really liked the defoamed 650 out of the β22. I also listened to the 600 and 580, all of which had the APS defoamed mod. I bought the 580 on the spot.

I was very surprised, as I've never cared for Senns. before hearing them through the β22.

To be honest the sub couldn't have been done without my friend Guido who did most of the hard work with the design actually, I was mostly learning from him and following his instructions

The cherry panels have darkened a bit over time and have a much nicer color now imho:






The sub sounds very good, my goal during the design/brainstorming phase was to have a fast, accurate sub that could go low, yet could also put out enough boom to be used as a HT sub. I'm thinking of building a small version to use for my bookshelf speakers I'm currently building.

That's a very nice amp you have there fierce! Just one question: why are your rear xlr's mounted from behind the panel but your front jack mounted on the front?

A tribute to the Pimeta!

Wow, lots of completely beautiful stuff lately!

I've recently had a chance to build an over-the-top transportable Pimeta with all the little additions I wanted.

This Pimeta runs off OPA637/OPA627 opamps with Millet Hybrid Discrete Diamond Buffers on Left/Right and a Sijosae Class-A Diamond Buffer on Ground.

There is a trickle charger for the 11x 650mAh AAA battery pack I soldered together. With the diamond buffers set fairly high (25mA each) battery life is about 10 hours. Of course, this could be lowered without much sound quality degradation.

This thing sounds fantastic and gives some chase to the PPA I'm using, but just can't catch up. I'll be finally having a chance to compare it to the PPAS, although I'm pretty sure which will win.

my beta22 coming along slowly...almost done though!



powered up...

gorgeous work. what kind of stepper is that? A DACT?

its a black ops Elna I scored off an under-paid genius up in New Hampshire

Well, Do I have "The Disease"?

After seeing all of the great builds in this thread I almost feel foolish posting my builds. But since I'm new to Amp building I'm still quite proud of my accomplishments. I built my first Cmoy 8 weeks ago and since then have completed those pictured, as well as another Mini^3 and JDS Cmoy not pictured.

From L/R - Altoids Ipod Dock, JDS Labs Bass Boost Cmoy, Mini^3-High Performance version with custom panel by FPE, (Bottom) another Bass Boost Cmoy in Box Enclosure, Alien Dac, (bottom) Pimeta w/ Opa637/627.

Now, off to source parts for a Millett Max.... I can't stop!

oh yeah, djbob... you caught the bug. Sorry about your wallet

Don't you just love Sijosae's buffer? I've made a couple so far what with my stash of 2N5087/2N5088 and that BUF634 shortage (though I just picked up 6 the other day), and the whole thing can be done in 5 minutes without even having to turn on your soldering gun. Simple and elegant, won't break the bank, and it's currently in supply. Excellent. Enjoy your PIMETA.

SOHA+Jisbos

djbob, I'm lovin the anodizing. Looks great.

As stated, yes, sorry to say, you've got the disease. Have fun. We all do here as well!

SOHA (standard Jeff build - thanks Jeff!) but with opa627's





Also alien dac.

That is probably the prettiest I've ever seen anyone make a Hammond enclosure! <3

cheers, i should thank the fiance's father for use of his workshop!
