yes, that's the plan. I may be doing a group buy for the Linear Systems JFETs, assuming there is enough demand. These will work fine with these boards if you cannot come across the Toshiba parts.

Price will be $40 per stereo set, with a few dollars for shipping from Germany to me (depends on the number of people interested, probably around $4) and then a few dollars shipping from me to you. The board files are available, but I'd rather go this route personally. I'll close this IC on Friday 7/11/08 and collect money over the weekend.

it's a pretty straightforward project really. no circular hole tech skills needed.

wow, intense thread. Perhaps everyone should just listen to more music, have a beer or two, do some DIY.....or all three:

I agree with this. What do you think of using multiple DACs in a moving-average type of configuration, similar to what Accuphase does here: http://www.accuphase.com/model/pdf/dp-700_e.pdf

by changing what was there, based on stuff that wasn't there?

ya, good show.

looking at this again, I think it can support MC carts as low as 0.4mV or so...

yeah, it cannot really be made into a phono stage with balanced outputs...

I think this will fall on deaf ears here

service manual and BOM for Pearl: http://www.passdiy.com/pdf/pearlphono.pdf grawk: the Xono has a balanced output, yes, but it's not generated how you might think. Here's a schematic of the MM portion of the Xono (edit: not the exact circuit, but same topology): http://www.rstaudio.de/AlephOno/Rev2/AlephOnoMM.pdf The circuits are indeed different, this is a common misconception.

nah, just 2 needed for balanced operation

seller has plenty...

I think it's worthwhile, because it marginally ensures that the tube has actually been stuck in a tester

Perhaps for a plate loading resistor design, what what about a proper CCS loaded tube, which will behave much more linearly?

mmm. i might be interested in the 15' ers ..

actually, I found someone with a stash of the original PCBs sold by PassDIY. So, I'm going to go this route myself. I will inquire on how many they have. Also, if anyone is wanting to split a pair (the boards are mono, so 2 required for stereo) I'm up for that too as I'd like a single board for a mono preamp.

well, depending on how linear the tube is, this may not be an issue... just like matching BJT hfe using a DMM might be an issue. I know some tube vendors that will honor this request.

I'm considering getting a few Pass Pearl phono PCBs made up. Is there any interest here?

shipped some stuff too.... waiting for PartsConnexion to have a sale on stuff I actually need...

ooh, thanks for the heads up.

do it. interesting idea

drunk shopping, or....... oh.
