I can easily be fooled into something like this.

Me too.

    Arrived yesterday and it really opens up every electrostatic headphone that I own. I was looking for an amp that can bring more bass out of my HE90 than HEV90 so I drained my pocket to bid on this and

  • I have been getting back at this..working up to a limited run of these as the STAX SR-X9000 and Audeze CRBN have made that need to happen. But the chassis is extraordinarily expensive and difficult to

  • Isn't everybody glad that I'm crazy enough to buy this stuff and have Kevin rip it apart?

For the case, the Nabu from Surplus Sales of Nebraska with a FPE panel would be a decent choice I think. MAT02 could work to replace the 2SK389, or the LSK389. 2SA1968 isnt difficult to find, just expensive. Check BDent, they have it in stock, and I have always had good luck with them before.

That case would work well and at that price it's tough to beat.

Gonna stick with board mounted heatsinks though, probably 2" tall SK129 profile.

please at least give an option for external heat sinking. This amp really improves with extra biasing and it's stupid simple to do...

What happened to "no stats in 08"? >:D

I failed that mantra ages ago.

Rules are meant to be broken. :prettyprincess:

I love Marc's Koss/KGSS combo!

And I never thought I would have one and now I have two Stax headphones and one Adapter and one amp. And now these have me thinking heavy about a Omega SR-001 Mk2.

Portable Omega would be awesome.

2sa1968's not needed for kgss. Think KGBH power supply.

Front end fets can be matched from single devices if necessary, but

lsk389 is a wonderful part.

So, step one is to track down the board files and specs for the amp and PS pcbs and I can get quotes. Are the old files in the PD somewhere?

there are a lot of shitty board designs out there... good luck on this endeavor. I hope you enjoy troubleshooting.

Glad to hear that you like them. It may be time to buy one now and use that black PC-OCC cable I've been saving for just that... :P Can you post some detailed pics of the back of the earcups to show how the cable attaches to the drivers?

I'm not sure if it would be worth the trouble pulling them apart to replace the cable. The problem is that the ear cups are glued in place (bad idea I know) and would have to be removed.

I probably misunderstood Nate then, I figured he was looking for old board files... carry on.

I'm in! What are we doing?

getting a bunch of sweet O2 capable amps. :dance:

It's the damn chassis work that gets me. Well, that and the soldering and troubleshooting and stuff--but the damn chassis work is the killer.

Friggen lawyers, never wanna get their hands dirty. :)

And I was talking about looking for whatever board files are out there, new, old, yet to be done. Doesn't matter a bit to me. If all that's available are shitty old board files then lets re-do them. I may be an ass but I don't generally do things half-assed. I'm a whole ass, damnit.

Then I'm in, dagummit! But, er, how much, y'know, like electricity am I gonna be exposed to? If there's one thing I like less than unlean hands, it's getting zapped.
