The ultimate DIY? A Stax SRM-T2!

Weight of amp chassis 15.56 lbs...(no circuit board, or tubes or other parts)

power supply would be the same plus 7.5 lbs of transformers (plus parts)

Great so my next diy project will be center supports for my desk :cool:

Between this, the b22 stack and my computer the thing is like to collapse into a pile of ikea fail.

Why your only looking at somewhere in the mid 20's (kg) weight wise for the t2, which really isn't bad at all... a 21" CRT monitor for example will weigh about 40kg.

By the way I assume it is too late to get on board (even if only for the boards)?

amplifier back panel. The amphenol power jacks can mount on the

inside as shown, so you can build it and wire it and then bolt it

to the back panel from the inside. Makes taking it apart if necessary

a breeze (something mikhail needed to learn). And the neutrik's are

in 2 pieces too...

Looking good. :)

How are you connecting the chassis earth? Through ground or a separate connector.

Neutrik nc3fdh connectors. Go look it up on their website.

krell uses a lot of these. you solder the inside piece to the

circuit board directly. Then insert thru the panel, add the outside

piece, and then there is a slot for a small screwdriver that locks

them together.

craig also uses them on his BA.

The one hole that is missing on the back panel is the hole for the ground

wire which connects thru the umbilical cable to the same place on the

power supply. Everything floats inside both boxes to get rid of any ground

noise. There is a switch on the amp board that connects amp ground to

chassis ground for those situations where it is necessary.

quick pic that explains the concept

Correction...

There is a switch on the amp board that connects amp ground to

the neutrik ground pin for those situations where it is necessary.

Like using the xlr for single ended inputs.

The outside of the xlr connector is connected to chassis ground.

I reread my earlier post and noticed it was rather unclear,

Should read, I assume it is too late to participate even if I'm more than willing to take a non complete set of spares.

Also $93.32 is surprisingly cheap which is rather nice compared to the 150-200 dollars a board quoted at the start of the thread.;)

That is just for the amp board sans shipping.

After getting both boards to your door it will prob be about 250ish for the board set like Kevin said earlier in the thread.

Was it not per board? (not board set).

Yeah, scratch that. Just did a bit of estimating on Imagineering and $150 per board is not at all out of the question. That would put me firmly out of the "I'll pitch in to help" camp. A $150 board I'll never use is not something I can do right now.

At least how I read the posts. Either way its far cheaper than I was expecting.:)

Edit:

The circuit boards are going to be $267 for the board set (one of each) if i buy 10 sets.
Looks like I just failed at reading.
