mind control device Actually, it's a tuner... play a note and it tells you if the pitch is correct.

heh, unless the gain is halved when doubling the boards. Doesn't the slew rate doubling happen only when you have a true differential input design, not when you glue four single ended amps together?

I have yet to figure this phenomena out. Have you tried the SR-007 with the KGSS, and do you have similar complaints there?

It's much easier to just modify the existing power supplies in your various components. Once you do that, the only thing you might look at is a nice isolation transformer.

jealous Fantastic work! I sent you a PM just now. Again, nice work! Since you've gone back to a four point routing shape for the board, what is the board size difference, I suppose I'll need that info for the board quote anyways.

sure why not. Either guess, or calculate things. I'd try some Black Gate N/NX as well... and the Russian teflon bypasses with the M-Caps that were included in your kit. Have fun with it

I'm assuming these would be for the Pearl? Things get a lot more expensive in the balanced world where you need double. I'd recommend looking at your signal chain and trying to go as low as you can with the caps, to save you some cash.

The place to upgrade the Pearl is the coupling caps. The same with the Xono, except you can be creative and bypass them all together.

no. The Ono was released and then recalled, once they realized what the Xono would look like once released

and expensive, once you look at the upper-end PCB material option with Caddock resistors.

I'd look at the Borbely phono stages, as well as the newer Pass designs that can be modified to be DC coupled. If tubes are your thing, consider the Alan Wright designs. The real question is how much gain do you need, and do you have an opposition to step-ups, or LCR RIAA transformers. edit: I fail at reading comprehension. Look at the Wright designs and the Borbely designs. However, the below still applies. The noise specs on the Pass designs is as good as you can get from a discrete design, IMHO.

... now for my next trick!

ah, clever. I was sorta wondering about that.

Cool! If you're looking down the road to just try the KG supply for the heck of it, I'd love to have a go at it for you. I have a few ideas of my own but they are in early gestation stages... and involves, among other tubes, a 12AX7 in the PSU for an error amplifier, which could be sorta weird for people... but, maybe I could just barely gain the KG seal of approval Just for the heck of it, I'd like to know the output voltages and currents though, if anyone happens to have a rough idea.

More a question than anything, and definitely doesn't deserve it's own thread... but, can anyone recommend a cheap tuner (no, the "other" kind of tuner)? I need something relatively portable, and not an "in-line" tuner. I was looking at a Seiko ST01, which is cheap and very portable, but other options would be appreciated

yay, the dissenting opinion begins! You can mark me down as a "meh" as well.

Yeah, I agree it's a hard choice, and it hasn't been set in stone. The cost differential is pretty high, almost 2x, as I can leverage the fact I've done a decent amount of business GP. At this point we really need numbers to be able to go any further.

... and low impedance

amb uses it for the beta22 boards

Don't you own a Singlepower amp? Anyone know what design this amp is based on, just out of curiosity?

cool! Is it possible then to utilize the 1x4 SIP header and the locations for the current sensing resistors on the prototyping board for anything, or are they more or less unusable? Icarium: Team vvs_75 requested 10 boards via PM, looks like you need to update their numbers.

Doug: In your PSUD2 sim, did you use a stepped load to check for ringing?

Looks like $12.50 per board is the magic number, made to the above specs. Dan charges $10 + shipping per board for the other Dyna- boards, as a comparison price point. This includes parts and shipping for two prototype boards, shipping from myself to Kevin and the initial run of the prototyping boards. This prototyping cost will be split up over the entire number of boards ordered, including Jacob's SMD only version. The divisor at the moment is 88 boards. Price is ultimately determined on the final number of boards ordered, so be noodling on that one.

don't they make clear wood?
