It is quite shocking that almost nothing can be salvaged from these amps but once fully rebuilt they do sound awesome.

Why Mr. Gilmore is very proud Singlepower ES2 owner, while (as Spritzer noticed) BH's sound is better?

I don't want to speak on anyone else's behalf but I'm guessing he likes it sounds ~fabulous~ once it's properly built.

 

I've never heard a BHSE, but I just finished up my own variation on the ES-X and t's a huge step up from the SRD-7 and SRM-1 mk2. I also got to try it with the SR-007, and the SRM-1 mk2 didn't stand a chance against it. Spritzer kindly sent me a schematic for a version with current sources on the output, which I built. I've since added current sources to the input as well- not a huge difference as far as I can hear. Mine's with 12AT7 like the original SR-X, and EL34s on the output.

 

I'd definitely encourage people to try it as a DIY project. It's fairly inexpensive and simple to build (no hard to source parts!), and I'd be surprised if any of the first party amps sounded as good. :)

That looks awesome!!!  I really need to finish my mini ESX one of these days.  6S4A's instead of the EL34

That would make a killer office setup! How small can you get the power supply? I got the 2u chassis just to fit the transformer and cap bank, but I'm guessing it'll be tiiiny and run way cooler if you forgo the ccs and EL34s.

It all fits in a 2U/400mm chassis.  I need to replace the PSU as this one is giving me issues.  It's a bad design but I've had it sitting on a shelf for a few years so I thought I might give it a shot.
