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...

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...

What transformer do you have?

PJ buy from retailers just like everybody else so their fault is the same as of Rinkya, KuboTen or the dozens and dozens of other companies who sell directly from Japan. They clearly have some source for the 009 that values sale volume over unit markup. The lowest markup a store should take is 30% (probably higher) so if somebody decided to charge half of their markup and sell 5 times as many units with nothing ever sitting in stock, then this makes perfect sense. Hell, I'd do the same thing. If you have the KGSS boards then just build those. There is a thread somewhere in the DIY section with instructions on how to build a KGSS and how to pick the parts. Feel free to bump that thread if you need any help or just PM me.

I wouldn't blame PJ for this, that price has stayed the same well before any refurb units existed. Hell with Stax there are normally no refurb anything... As for the production, based on the interview on HF? Very little of that piece is actually true.
-
The KGSS and KGSSHV are very similar so you might need to use those values. I don't think anybody has tried the HV at these voltages though. Don't mess with the input resistors. You can leave the - one out as the fet is grounded on that side but the + side needs to be 500K to protect the fet should the pot ever float.
-
Now here is thought... maybe this is a refurb? All those units sent in for repair from the US get replaced so they have to go somewhere. I opened up mine and it's pretty much the nightmare of the SR-Omega but made worse with screws. The SR-007 pads are a joy compared to the 009...
-
Both amps are excellent when modified. Pretty much transformed over the stock versions...
-
How hot is that thing running with 1K cathode resistors?
-
The EML tubes in an octal base for DHT's but there are some very good triode strapped pentodes out there. I do have a fondness for odd tubes nobody uses though...
-
Get them out of the closet!!!!
-
The first trouble with a 300B amp is running it single ended through a transformer. So we can improve performance by using a simpler transformer. Also better drivers help but I'd still use a large number of tube besides the 300B...
-
That would certainly account for the offset. Bypassing the current limiter might work but it could also end badly...

-
The 1968's would be my guess as well.
