I was just floored by the SOHA II. I am somewhat tempted by the new offerings, but I think the SOHA II can really be tweaked and probably has more potential if you're willing to understand the circuit and try some new things... the all-in-one board makes this a bit difficult, but it can be done.

my bad. I could have sworn I read the word "discrete"... searching around, I just see jp# calling this discrete over at head-fi. By "fail" I was referring to the fact that this would be rather misleading if it was indeed the case, as Justin predicted. I've used a 2-3 different THAT chips and similar ones made by Analog.... mainly in phono stages, which is probably one of the better applications for them. They are not at all transparent. I hope to have better luck with transformers in this sort of role.

1.8V is practically zero in electrostatic world.. heck, 10V is practically zero.

I cannot make it. However, can I ship some gear to someone to try and sell it there? Is there a spare table or two that could comfortably house my gear? If some Head-Fi noobs don't have room to setup, that's fine by me. Wait, I just had another idea, can I sell raffle tickets as well, even though I cannot make it? You wouldn't have to be present to win, of course..

EAGLE's size restrictions are just a compelling reason to switch to Diptrace (and deal with its pin limits)

... wait, an all discrete amp that uses opamps for balanced to se conversion? :fail:

interesting observation. Looking at the curves for 6080, I suppose the question is, what's the voltage sitting on them. Also, perhaps its a new production 5U4 with improved specs? That would kinda bite tube rollers a bit though, so that's probably unlikely...

Mike: I was looking around yesterday for some spade terminals especially fit for a phono stage binding post and noticed that both Cardas and Vampire make spades especially for vintage gear using barrier strips, such as your Mac amp. Here's some pics: Anyways, not that I'm advocating better cables in your setup, but just happened to notice these...

Steve: They were all there when I repacked the little kits. I double checked. Most troubling. I can order the parts for you if you'd like, just PM me. Might as well pick up the missing Zetex transistors as well, they're dirt cheap.

from what little I know, no. I believe he works at National.

I think the reason the locking mechanism is left in is that XLR jacks don't have the same contact force that RCA jacks do. I know amb has said this a few times, as have a few people on other boards who seem to give a knee-jerk disapproval when they see pics of jacks with the mechanisms removed.

if so, why don't we add Rowan Williams to the mix...

Voltron: if you stumble across anything with a DIY slant, I'd be interested in giving something like this a try as well.

nah, some opamp based thing for an electronics course, but that's my point

my first DIY project was the best sounding amp I've ever built

depends on the upgrades I'd assume, like the 384kHz options.

A 5V fixed regulator, >1A. Like, LM323T or KA78T05 Available at Mouser for pennies I'm sure .. if no one has one and a envelope, I'll probably just shelve this until the next oversight

yay......... the F1 wasn't even meant to drive dynamic drivers, so actually making an amp that was designed to do this would be a huge improvement.

I just bit the bullet and ordered the stax jack jig. Should be here the end of the month.

heh. I just saw "KGSS" and "bias" in the same sentence, despite the fact that this is a Koss thread.

ummm...... er.. yes, it is adjustable on the inside maybe not in the manner you are thinking... oh wait, *that* bias... erm.. yeah!

the above's younger brother

use the schematic, it will be much easier than looking at the board silk, and much less error prone.

I don't have a schematic. I do have a schematic for another Ayre product and the complexity is mind boggling.

30 pairs of the output devices used in the Ayre V-5xe. Not that I know what I'm going to do with them... but...
