July 5, 201312 yr Looks great Lil Knight! Just wondering if you managed to test it out with the amp boards, yet. Wondering if there are any sonic differences from the older sand to take note of?
July 5, 201312 yr Got the new mini PSU powered up fine Voltage is pretty much right on. I am using new devices, ksc5026 and ksa1156, instead of the 2sc3840 and 2sa1486. I want some, Lil Knight!
July 5, 201312 yr Good job all round gentlemen. Will you make the pcb available to us now? As usual, gerber file to make boards is available from Dr Gilmore. Just ask nicely. Just wondering if you managed to test it out with the amp boards, yet. Wondering if there are any sonic differences from the older sand to take note of? I am waiting for the peek screws to test with the new mini amp boards which use all new devices. When everything is done, I will try to compare with my old KGSSHV. Sonic differences... might be yes, but very small, I guess. The main advantage is everything can be sourced from a single vendor which is a huge plus. Mouser now has the 2.5" Aavid heatsinks so we don't have to order them from Digikey. I compared the Aavid with the 2.5" Ohmite in my BOM and the former is a clear winner. Group buy will be opened in a day or two. Thinking of what other boards should we order?

Looking forward to your A/B comparison. As to other boards... maybe the prototype Megatron?
July 5, 201312 yr KGTT? BH? Megatron? I like how we all get excited when Lil Knight says "what other boards" I'm also down for KG's unbalanced to balanced board (http://gilmore.chem.northwestern.edu/ubaltobald.jpg) if you're making some
July 5, 201312 yr I don't think the BH will ever be released to public. But the Megatron is very tempting indeed.... Other boards I'd love to try or prototype are the onboard Dynahi, KSA5 and Dynalo. I've just stopped by the machine shop to pick up my custom case for this KGSSHV. Haven't finished the front panels, but here is the bottom plate. Very compact and the PSU and amp are the same size A stack of them would be awesome, I hope.
July 5, 201312 yr Very nice Tran. How many builds this year so far? I have 1 DAC, 3 dynamic amps and 3 electrostats.... but nothing totally finished. Hi Tran, What is the size of your bottom plate? It's 215mm x 300mm. Might hard to squeeze in a large pot like the Khozmo or RK50, but something like the DACT or Alpha would be just fine.
July 5, 201312 yr I'm hoping to have a go at stuffing one of the tiny PS boards into the exstata when it returns stateside.
July 5, 201312 yr I have a couple of spare ones left from the last order, so if you really need it fast, I can ship out to you.
July 5, 201312 yr No worries but thanks for the offer. I don't have the amp back in my possession yet so there's no rush whatsoever.
July 5, 201312 yr I don't think the BH will ever be released to public. But the Megatron is very tempting indeed.... Other boards I'd love to try or prototype are the onboard Dynahi, KSA5 and Dynalo. +1 for megatron
July 5, 201312 yr Id be interested in a set of the new smaller KGSSHV boards, now that I'm getting back in headphones after a brief exit to speakers. I would also be interested in a set of boards for that new SuSy Dynalo, and I would buy a set of Megatron boards if they were offered just in case at some point in the future I felt like putting it together I ever got the balls to build one.
July 6, 201312 yr I don't think the BH will ever be released to public. But the Megatron is very tempting indeed.... Other boards I'd love to try or prototype are the onboard Dynahi, KSA5 and Dynalo. Mini KGSSHV and Megatron Thanks everyone effected these great amps!
July 6, 201312 yr Author introducing the .... KNOB OF BIRGIR http://gilmore.chem.northwestern.edu/knobs4.jpg only my second absolutely perfect ebony knob out of piles of ebony. birgir's birthday present for his ecp L2. and a black and white ebony blank from a very overpriced 3 x 3 x 12 piece of ebony guaranteed no cracks with 2 actual cracks, and which I will be able to make no more than 4 knobs out of. Edited July 6, 201312 yr by kevin gilmore
July 6, 201312 yr So beautiful!! I've got a similar sized block of ebony and will be attempting a knob and surrounds for the jacks.
July 6, 201312 yr Author The inside piece and the blind alignment and the hole smaller than the 4-40 set screw are loads of fun. Have to indicate everything to .0001 hole in the wood only .045 just barely big enough for the allen key.
July 6, 201312 yr THE KNOB OF BIRGIR will become a legend.....Strikes a chord, we used to have Nordic sagas when I was at primary school.A very nice bit of skill Dr Gilmore.
