Megatron Electrostatic Headphone Amplifier
I would also run the raw mains on a separate umbilical. For safety and all that something like the Neutrik Powerkon would be perfect.

The filament transformer for the CCS tubes have to be close to the amplifier board.

The ultimate DIY? A Stax SRM-T2!
Assuming the transformers behave then a bracket isn't an issue. Supporting the weight and all that goes without saying and it would be a good idea to allow for some holes to cool the transformers.

The ultimate DIY? A Stax SRM-T2!
My front panels are laser cut but for the silver they put some material on it that the laser burns into the front panel. They are done by a place that normally makes small signs and the cost varies on a number of factors. Around 100$ or more for a panel is the norm.

New HiFiMAN headphones
That's true but unspecified upgrades aren't helpful to anybody and make the forum lemmings run wild. Remember the whole "white driver HD650" BS?

The Headcase Stax thread
The SR-Omega prices are reaching into the "are you nuts!!!" spectrum so the Mk1 should be on the rise too. Personally I'll just be happy with a SZ2...

I think they do what Stax does and simply replace with what ever is in current production.

Yup and it's a mosfet that actually doesn't suck for this role.

I decided to try something new for the next round of HV's: I like the "black line" look and it will fit with the next batch of amps using some exciting transistors.

The Headcase Stax thread
These are very hard to work on so I wouldn't attempt a DIY repair and have Stax do it. The cable might still work but it's a very old Mk1 so the cable is doomed regardless... Also check for dust in the drivers as that's one of the reasons the housing was changed. All the early Mk1 drivers I have here were removed due to dust issues.

I think Wachara did that at one point.

The Headcase Stax thread
Early sets are always a problem,personally I wouldn't touch an early SR-Omega with a 10' pole. That set will probably need a new cable and definitely new arc and headpad. Budget 500$ or so for that...

Been listening to the KGST and it does sound pretty good indeed. It's a bit shocking how close it comes to the BH, throwing that same deep soundstage with a rock solid foundation. Now the BH is still better but this is damn close...

Sound design vs amp design?
Ari nailed it but I'd like to add that many designers, while trying to do their own thing, often make grave errors. Important factors are simply glanced over or others deemed "not important". Ari says we are crazy to run our amps on such high voltage rails (and he's right) but that's a better approach than RSA with the A-10, "who listens that loud?". Then we have the flipside where a design is supposed to be this and that regardless of how it will sound. No better example of that than then the EC Electra. The bottom line though is any designer must have a good idea what the end result should be regardless of what is being designed.

I'd check the bottom just to be sure. Then you can start replacing parts.

First thing first, you had shorts so were all of them properly isolated and cleaned? All resistors measured out of the circuit (one end lifted up)? With a short you can even damage the PCB.

Post what you're watching
You should check out "The Guard" too if you haven't seen it for some more Gleeson goodness.

I haven't had enough time with this version yet but the design offers a nice middle ground between the BH and the KGSSHV. That's also why we picked it as a starting point to do a 009 amp...

Need a Solid State Headphone amp for LCD X-Recommendation please
My hero, single volume control and loopouts!!!

New HiFiMAN headphones
Yay for selling half finished garbage. Just wait for the overpriced piece of shit they have in store for the electrostatics. I couldn't stop laughing when I heard about it and they might even beat Woo and RSA for worst ever electrostatic amp.

Looks good, one thing to check though, is the pot dead. That has happened once to me.
