The input switch changes color when you push it in and out. (it actually does this mechanically) craig just loves to use antique parts that are generally not available.

TTVJ Portable Question
The TTVJ portable uses a switcher inside to run the output section at +/- 5 volts 3.29VRMS is 9.2 volts peak to peak which comes about as close as posible to rail to rail. Not sure what is inside the ALO, but 7.45 VPP is 2.66 VRMS

Thanks kerry, that is exactly what i'm looking for. I'll use normal stuff for the filaments.

The ultimate DIY? A Stax SRM-T2!
Anyone know of rational pricing on wire?? Want 11 different colors, each 20awg, 600volt or cable with 15 wires in it, each 20awg 600volt each amp would use about 10 feet total of 15 wires...

The ultimate DIY? A Stax SRM-T2!
After the prototype is done and working, i will send 5 sets of chassis parts to be finished, then order some more front/back material as i only have enough of that for the first 8 units. If you want some other color than black, i can ship you the stuff unfinished and you can find someone to finish it to your liking. For those that want a jump start, i can sell board sets now... But really i don't need any money till i'm ready to ship stuff.

power supply boards just arrived. and all other parts are on order (i think) (i certainly hope so)

The boxes are 16.5 deep and 15.5 wide ! Bottom feet are at about 10 inches x 13.5 inches. When you see the power supply stuffed, you will know why it has to be this big.

http://gilmore.chem.northwestern.edu/t2chassis20.jpg http://gilmore.chem.northwestern.edu/t2chassis21.jpg as a tip of the hat to my friend mikhail, singlepower chassis screws temporarily holding in the neutrik connectors 6-32 screw goes into the keystone 7700 on the board.

Audiophile Chairs
I've had an ekornes for about 20 years. Love it a lot. Every 6 months i have to get out the tool kit and tighten up the main hexhead bolts that hold the thing together. Every time you rock it back and forth, the bolts come loose a bit. If they come out all the way, you need another person to hold it place otherwise you can't force it back together. Leather finally wearing a bit after 20 years.

I think that justin's board stuffing rates have just gone up. I wonder if he would accept $100 an hour for this kind of pain

The ultimate DIY? A Stax SRM-T2!
So with the proper tools that i made myself, stuffing the heatsinked transistors was a snap. Picture with the tools on the left. Since the tools are dirt cheap (they take me less than a minute to make) i will probably supply them in the kit. Better than spending over $300 on the real tool. tool widths... .1618, .3271,.4780,.5780 I'm going to stick with the following numbers superman (as in justin) assembly time 6 hours me (as in me) assembly time 9 hours normal human (everyone else) 12 hours http://gilmore.chem.northwestern.edu/t2ampboard2.jpg

But there are 2 power supply connectors, and the whole thing is wired completely as dual mono. So i built the thing completely so i did not have to go thru the pile of resistors twice. I can and likely will power up only half of it the first time. Besides which the power supply will be tested completely first.

after 6 hours of board stuffing http://gilmore.chem.northwestern.edu/t2ampboard1.jpg only errors so far, on one side of the amp 2 of the resistors are labeled as 100k when they are in fact 10k. Obviously everything fits perfect. Custom stainless steel hex head screws the exact length should be in tomorrow, then i can mount the stuff on the heatsinks. trimpots go on the top of the board for easy adjustment. missing resistors are backorder A reasonable person should be able to stuff the board in 12 hours... Not so bad

The ultimate DIY? A Stax SRM-T2!
Its the quality i care about, i really don't care where they are made. A long time ago i had some boards made by a board house definitely in the usa, because i was at their factory in lake in the hills illinois. The stuff was crap.

The ultimate DIY? A Stax SRM-T2!
updated parts spreadsheet including resistors for the power supply and the .1uf/50 volt caps i was missing as i stuffed the board... (what a mess... the spreadsheet that is, the board is gorgeous) having imagineering do the circuit boards was definitely a good idea even though they cost a bit more. Solders just great. http://gilmore.chem.northwestern.edu/t2parts3.xls stax X1t ------------- NOPE! but i am getting closer to wireless hdmi based SACD...

The ultimate DIY? A Stax SRM-T2!
shipped power supply board this morning. parts stuffing starts possibly today. No later than saturday morning. fact is i'm sure i'm missing a few parts. I can stuff parts and solder the board in 4 hours! (I'm lying my ass off. )

Wanted: A Builder to construct and case-up a Stax Bias Supply
As goofy as it sounds, this will actually work. Make absolutely sure you don't get the ac input wires to spritzers board backwards as its not isolated and you want to make sure neutral and ground are the same. Which might cause a ground loop.
