RiStaR Posted July 5, 2013 Report Posted July 5, 2013 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?
chinsettawong Posted July 5, 2013 Report Posted July 5, 2013 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!
eggil Posted July 5, 2013 Report Posted July 5, 2013 Boy, they are small. Now I want one for my office!
Lil Knight Posted July 5, 2013 Report Posted July 5, 2013 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?

RiStaR Posted July 5, 2013 Report Posted July 5, 2013 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
Lil Knight Posted July 5, 2013 Report Posted July 5, 2013 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.
Victor Chew Posted July 5, 2013 Report Posted July 5, 2013 Very nice Tran. How many builds this year so far?
chinsettawong Posted July 5, 2013 Report Posted July 5, 2013 Hi Tran, What is the size of your bottom plate?
Lil Knight Posted July 5, 2013 Report Posted July 5, 2013 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.
n_maher Posted July 5, 2013 Report Posted July 5, 2013 I'm hoping to have a go at stuffing one of the tiny PS boards into the exstata when it returns stateside.
Lil Knight Posted July 5, 2013 Report Posted July 5, 2013 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.
n_maher Posted July 5, 2013 Report Posted July 5, 2013 No worries but thanks for the offer. I don't have the amp back in my possession yet so there's no rush whatsoever.
chiguy Posted July 5, 2013 Report Posted July 5, 2013 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
SoupRKnowva Posted July 5, 2013 Report Posted July 5, 2013 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.
palchiu Posted July 6, 2013 Report Posted July 6, 2013 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!
kevin gilmore Posted July 6, 2013 Author Report Posted July 6, 2013 (edited) 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, 2013 by kevin gilmore 2
Kerry Posted July 6, 2013 Report Posted July 6, 2013 So beautiful!! I've got a similar sized block of ebony and will be attempting a knob and surrounds for the jacks.
kevin gilmore Posted July 6, 2013 Author Report Posted July 6, 2013 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.
headinclouds Posted July 6, 2013 Report Posted July 6, 2013 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.
