Yup, low risk of damage but I would buy the roughly 1$ in parts and fix this.

The Headcase Stax thread
Let's just say not so fucking harsh and hard sounding.

Woo Audio GES
Ehhh what the fuck is wrong with Woo Audio? So this is not up to spec but it is at least closer than many of the latter amp. So this is voltage divider off the main B+ which should be 600V. It's 121K into a 3M6 shunt which gives us 580V. That's ok but then they put a 3M6 ballast resistor... It should be 4M7 so this is close but not correct. I would change it and to a proper high voltage rated resistor too but this is close enough in value to not hurt the phones. On the newer amps I've seen it as low as a few hundred K if there is even a ballast resistor at all...

The Headcase Stax thread
Yeah, they might even be doing this just to fuck with us. On top of this...the SR-007A is now available in black color... I might pickup a new set in the new year to try out the current crop just to make sure they haven't changed them yet again. That and the new SR-009 project will be thrown into full force. Basically...I'm going to make new diaphragms for the 009's to change how they sound i.e. how they should have sounded in the first fucking place.

This is an older amp so it should be ok. I need close up pics of where the red wire from the headphone socket is connected to be sure. I can't read the resistors from this angle.

The bottom should do it. You might want to check the top covers as well as they have been known to use some pretty crappy PSU caps in these...

The Multi Amp aka Dynalo Mk2
Yeah, this isn't a laboratory grade voltage standard either. If it were then everything would be suspect, how the board was constructed, internal stresses, are the solder joints contaminated and it goes on and on...
-
Woo Audio GES
Certainly. You need to remove at least the bottom panel so we can see how it is built. Maybe the top covers for each of the modules there but I don't think it would be necessary.

square wave
That was my point back then. There were and still are plenty of matched dual unit which are "cheap" and certainly easier to deal with for the noobs. Also here, this really wasn't a factor at all, let alone if the circuit had been done right in the first place. I do remember all the drafts (I think i still have many of them) where one was more silly than the rest. Then I bought the SRM-1 Mk2 schematic and sent it to Cavalli and then suddenly there was a working circuit. Guess what that 1982 circuit is also lacking...

The Headcase Stax thread
It's impossible to tell what Stax are up to, even whether they have messed with the design yet again. I mean they were perfect or just about but since when has that stopped anybody from messing with a design?
-
square wave
I remember when they dismissed my comments about that back in the day, goes to show why the whole cult aspect of Cavalli was so stupid. Nobody called him out on his stupidity and lord knows there was a lot of that going around... Another bit were the input devices, needing to match those not just into pairs but to a specific range. How that was a good idea in a budget amp is beyond me...

We need more SS amps with output caps. Who doesn't like the sound of electrolytic caps in the signal path?

Go power bricks!!! We should post some of the internal pics of the SS-1 now...

I'd stay away from HP as well. I was in this boat a few weeks ago and I bought a Xiaomi Air 13.3 and I love it. It came with Chinese Win10 but I removed it and installed new Win Pro instead.- Sennheiser HE-1
Hehe I can believe that. That's why I so want to get one without the built in amp and roll my own.
