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...

Just curious, of all of the DACs that you've listened to, how low has your end transducer been able to accurately reproduce? I feel that the important differences in jitter manifest themselves predominantly in low(er) frequencies.

my measurements look right on. Now to find someone who is placing a FPE order soon. I don't want to pay another $8 for a 2 sq in. FPE design that already costs >$30

You need to try it in higher concentrations.... use bitter almonds.. they work better... or maybe cassava leaves.

I don't know, have you tried good ole fashion, non-RoHS lead? Or perhaps almond-plated?

I was wondering if the bear grabbing the two kiddos was a biblical reference...

Reks needs to experiment more with shovel plating. He's very predisposed.
