Icarium organized one a while ago, it worked out in the end, but it was a lot of hassle IIRC.

Can't go wrong with something Rudistor approved. APL is using them too these days...

For those of us without access to the casino, was Gilmore permanently banned, and for what? He was a very interesting read, even if most flew over my head...I haven't seen anything mentioned about this, I am guessing it has to do with the ChiUni stuff?

talking about bans after 13 posts is not always the best idea...

good point...I was curious and I apologize..not sure what got into me this morning...

don't worry about me, I unfortunately only wield one of these:

It's the others you have to worry about.

I'm back to reading and keeping my mouth shut, apologizes to all. I do not want to end up in reks's basement.

Have you given thought to upgrading to the titanium version? If it works well for knobs, it must work well for shovels too!

Despite almost single-handedly dissolving Head-Case, I have no real power. I have a feeling they'll take away my plastic shovel now that they know I have one

OK, the holdup for the last 5 weeks was trying to supply 2sa1968LS at a rational price. ($7.13 each is not rational)

I was told by the person that should know that they should be 70 cents each. So after contacting various

unsavory ic parts companies only to be told that my offer of $1.29 (mouser price on the ixtp compatible part)

was WAY too low, i just gave up and decided to modify the layout of the board to incorporate both current

sources. Literally 10 minutes after i uploaded the files below, i get an email with a quote from a british

distributor, and guess what... 70 cents each. (plus or minus due to exchange rate)

Since lots of things have been changed or moved around, lots of checking needs to be done.

also apparent discrepancies on the power supply schematic vs the amp board are due to the

differences in voltage. If you go with the 2sa1968ls which i think sounds ever so slightly sweeter,

the power supply rails have to be +/-450 volts. If you go with the ixtp01n100d, then you can

go with +/-500 volt rails.

The amp board is 8.25 x 6.25 inches with 240 holes. you need 2

The power supply board is 9 x 7.5 with 374 holes.

The single transformer is going to be 4.5 inches in diameter and about 2.5 inches high.

(if you go with the SumR)

If i do the board run and do 20 sets, because i'm in illinois and so is imagineering...

the price increases by 9.5% due to sales tax. Which would make a complete board set $71.46. plus shipping.

If someone else wants to do the board run that's ok too, gerber files will be posted once

people verify that there are no mistakes.

Digikey is the only one with the 2.5 inch version of the aavid heatsink, mouser only stocks the 2 inch version.

2.5 inch version highly recommended. BOM now needs serious work.

I'm not doing chassis on this one. (well except for my nelson pass style chassis which is for me only)

Put it in a hifi2000 box, or hammond box, or a wood box. But plenty of top and bottom holes.

Thanks for your fanastic input into the community Kevin.

Who was that? Dalbani/Nikko or some other one I haven't found yet? That price seems very good.

OK - I'll bite - put me down for a set. After all, how many KG designs does a man need? Um, how about a full house....

In the UK Farnell stock them (at least if we're talking Aavid 6300BG), their part number 1213471 at

Does sweeter necessarily mean better? Also mark me down as interested in a board set.
