The first problem with that amp are the tubes used, 6SN7 and 2A3/300B are all fine tubes but should not be used together. The 6SN7 just doesn't have what it takes to drive the DHT's properly. Why this combo is so widely used just goes to show why most of high-end audio is just the same crap done over and over and over again. The 6SN7 would be a fine input tube (though the ECC's are more modern and better) and then something else to drive the DHT's. A cheap one in current production is the ECC99 which was designed for this role. The Russian version would also work. Second issue are the transformers used by Woo. In every Woo product I've taken apart the transformers are dirt cheap garbage. Seriously, anybody thinking the Woo Wee is better than a Stax SRD-7 is just delusional. In a simple amp such as this the quality of the transformer is paramount so I wouldn't settle for anything less than a bifilar wound C-core, done by somebody who knows what they are doing. Lastly the power supplies. This is Woo after all so we all know the power supply is fucked. Rectifier tube run way past its rating to help people believe rolling them makes a difference?

Well... it is more similar than not. Lower voltage but the KGSSHV was never really about the voltage...

Gotta love subminiatures. I need to finish my Stax submini amp...

Well... they didn't. The bias was also not nearly has high.

This one is more like "inspired" by the original Squarewave than a direct copy.

This stuff isn't about high quality, it's just about using tubes people know about and can waste an untold amount of money to roll.

Mine is pretty different so it hard to compare against this version. If anybody has heard a fixed SRM-007t it's like that except more better.

Sleep is overrated anyway and way to go.

Expensive equals good. Sprinkle on some DHT's and it is awsome!!!

Yes, the Mk1 which we have always said is exactly the same as the Mk2 except some minor PCB stuff. It was always completely different though and pretty much crap... horrendous crap that nobody in their right mind should have bought. Looking at the available pics the Mk2 is still the same garbage, same cheap PCB's, same parts used, same crap build quality, same non working and dangerous bias supply and I think the Mk1 chassis might have been better. Hard to tell though without a hands on review but quality steel chassis is better than a cheap alu unit.

Some shills...

That case used to be our version of the LL but it made no sense to finalize it so the mini ESX inherited the case. That one has the original Exstata PSU which naturally is shit so that needs to be fixed.

It could be a NOS 6973 but they go for silly prices.

Yes, if Alex had any clue. This one is also cheaper to build when done at lower voltages. It's been one of these projects that has been on the backburner for way too long. Here is mine, adapted from boards Marc did and pretty close to what I'm doing with the SRM-007t. Still in that... works but not finished stage along with dozens and dozens of other projects. Been like this since 2011...

Always have faith in clueless people staying with their clueless nature. Well that and I've had the schematic for that abomination for years... Those are 6S4A's so they at least got something right.

To add to this then there is the mod to the SRM-007t which turns it into a KGST, aka a mini BHSE.

About bloody time!!!

Open in up and post a picture of the transformer. Especially the leads going to the power input.

That mobo is nuts... I like it!! I did something similar today but not as high end. i5-4430 processor, 16gb ram, 120gb SSD and HD7770. I reused my old Antek case which was not fun since it has the same layout as above but the power leads were all too short. Had to extent the AUX procesor power lead about 10" to get over the back of the chassis. Ohh and the case had no provisions for 2.5" HDD's so I just used some foam to wedge it in between the two older HDD's... The real reason I upgraded was the new Dell U2713HM though...

Nope, it always sounds like this. That's also the reason why I don't own one...

It could actually be quite a bit worse...

The entire SRA-3S draws about 30W so nothing in there goes past 1A.

The SumR unit in my first KGSSHV blew up so Richard sent me two replacements to see what the hell is going on. I'm working on getting them through customs now without it costing an arm and a leg. That is too low for a Megatron. I'd go with 420V/200ma as you are driving 8 EL34's. How hot is the transformer at full load? I'll probably use a 2*335V/200mA Edcor transformer as I have a few sitting here and running it at +/-400V is a good idea in my book. Less heat and all that...

I'd start with disconnecting the trafo and testing it.

Mine ran for two years before it crapped out...
