Maybe this is how it went down?

No, Edifier owns STAX. or did you mean own like as in pwnage?

https://www.headamp.com/blogs/news/sony-buys-audeze The information they sent to dealers says that the company will remain independent with the same management and they'll continue to develop gaming products for non-Sony platforms

I just realized, while working on a hand-drilled prototype, how much more likely it is for this type of thing to be problematic for a one-off or a DIY project that doesn't have CNC machined holes, pre-calculated lead bends, and things that result in the transistor lining up perfectly with the hole. Even many hand drilled/DIY projects where the transistor 'lines up' there may be force required to get it in place, a screw head going in at an angle - due to placement of the transistor, the hole drilled at an angle or both...all recipes for issues with insulators

Colin should build it

yes but I ordered them as a scored panel

UberAmp2. it's like a headphone amp, but with more voltage and current. 4 boards = 2 balanced channels

If those are the only 2 options id go with the 100v but if its a 115v primary not a 120 or you have high line voltage you’ll want to go to 200v+ rated caps for this board the difference in heatsinking isnt going to be a lot

did you use Kevin's board files? correct they wont work with CT

I ordered some panels of these. I’ll send a free panel if anyone is willing to build/test one once they receive it

I decided to order some of these, 4oz copper, panelized/scored. Gilmore Purple People Eater, because purple is the most uber color the PCBs will be available if anyone wants a set

another thing that gets people is not deburring their tapped holes ive had to deburr entire batches of Aavid heatsinks before

What HV section?

what about the 90C version which is 900v instead of 800v

measure the DC voltage to ground at every node in the circuit, and write it down on the schematic, will be very helpful also do you have pF caps across the feedback resistor in SS Mode?

Need to start matching these but liking the results from the basic tester so far

SR-X9000 just passed 1,000 units manufactured. Took just under 2 years

Reality is like this though

confirmed: tubes are inside

This may not happen again..here is a never opened box of Philips ECG 6S4A tubes, USA made, delivered to a defense depot in utah (dry climate!) in 1983 very curious to see how they match think the box is actually full of tubes?

I usually buy the XLR jacks with separate Pin 1 and chassis connection and then can test it with jumpers on the input board. Nelson Pass said he connects pin 1 to audio ground, though it was 15+ years ago he posted it on diyaudio. I think also people who are using XLR/RCA adapters are under the assumption Pin 1 is ground I can connect Pin 1 to chassis only but unless something has changed in 15 years, my experience has been that customers report fewer issues when it's connected to audio ground.

some of the quietest gear ends up accidentally built by people putting ground or chassis connections wherever they feel like it, even places they don't know about btw almost all of the audiophile type gear I've ever seen is connecting Pin 1 directly to an audio ground plane. In some cases this is even bypassing the ground break circuit

8x10 is pretty small, so make good use of the vertical walls also consider a wall mounted tankless water heater to reclaim the space

if you can ship it and it still works..yes

I completely forgot about McAllister
