insanity Posted June 28, 2015 Report Share Posted June 28, 2015 IMHO the fat version of the PCB looks very interesting and opens new options for the case layout. Quote Link to comment Share on other sites More sharing options...
mwl168 Posted June 28, 2015 Author Report Share Posted June 28, 2015 Thanks Kevin. Should I re-trace the dual power supply board? Quote Link to comment Share on other sites More sharing options...
mwl168 Posted June 28, 2015 Author Report Share Posted June 28, 2015 @mwl168 I have heard from sorenb that there were some quality issues with the kgst boards from the recent GB. I cannot comment on this, because I have not used my boards I got from this GB yet. Therefore the question: Will you be using the same manufacturer or anonther? I think for an Amp such as the Carbon higher quality PCBs could really be justified, even if it adds a bit to the cost. Sorenb brough the issue to my attention as well. I do plan on using a different fab house for this GB just don't know which one yet. Please do let me know if you run into PCB quality issue with your KGST boards. I will file a complaint with the manufacture. Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted June 28, 2015 Report Share Posted June 28, 2015 if you have the time check every one of them, but all i did was change a couple of silk screen labels, and a couple of .6 resistors into .5 which are easier for people to bend. the others are just cut and paste from the original Quote Link to comment Share on other sites More sharing options...
adasdes Posted June 28, 2015 Report Share Posted June 28, 2015 Thanks for putting this together. I would like: 2x amp sets (4 pieces) 1x single psu set (2 pieces) 1x dual psu (1 piece) Quote Link to comment Share on other sites More sharing options...
gepardcv Posted June 28, 2015 Report Share Posted June 28, 2015 Have we decided if the split PSU on this GB is the fat or skinny version (or both)? Aside from size, the difference between the fat and skinny is the orientation of the angle bracket holes, yes? Quote Link to comment Share on other sites More sharing options...
Victor Chew Posted June 29, 2015 Report Share Posted June 29, 2015 Thanks for putting this together. 1 set for me please - 2amp boards, and 1 dual psu. Tks. Quote Link to comment Share on other sites More sharing options...
mwl168 Posted June 29, 2015 Author Report Share Posted June 29, 2015 (edited) Have we decided if the split PSU on this GB is the fat or skinny version (or both)? Aside from size, the difference between the fat and skinny is the orientation of the angle bracket holes, yes? The "fat" single PS was released after the GB was started. I believe the only difference between the "fat" and "skinny" single PSU is the dimension of the PCB based on my quick look through gerber file viewer. Kevin will have to confirm. My guess is the fat single PSU was created to facilitate flexible boxing layout and options. I need to ask all those that have expressed interest in the single PSU to edit your response and specify specifically if you want the "fat" or "skinny" single PSU if you have not already done so. I will be getting a spreadsheet listing the participants and options started and posted her at the appropriate time. Thanks!

wokstarr26 Posted June 29, 2015 Report Share Posted June 29, 2015 Personally I like the fat single power supply for more flexible mounting options. I have aready modified my post response. Quote Link to comment Share on other sites More sharing options...
insanity Posted June 29, 2015 Report Share Posted June 29, 2015 I would also opt for the fat version and change my GB wish to: 2 sets of amp boards, 2 sets of splitpsu (fat version) @mwl168 It will be a long time until I use my kgst boards. They are just as a backup. Quote Link to comment Share on other sites More sharing options...
DefQon Posted June 29, 2015 Report Share Posted June 29, 2015 (edited) Going to be broke from buying all these boards, is this any less expensive to build compared to the other kgsshv's? Might have to skip this one out. I'm still waiting for a Megatron and DIYT2 PCB gb Mike. Edited June 29, 2015 by DefQon Quote Link to comment Share on other sites More sharing options...
nopants Posted June 29, 2015 Report Share Posted June 29, 2015 the output stage costs less and uses in production parts Quote Link to comment Share on other sites More sharing options...
insanity Posted June 29, 2015 Report Share Posted June 29, 2015 I have done a preliminary BOM with some spare materials, but I estimate the mouser parts alone without spares would be around 300+ dollars. Let alone the PSU Caps are 4*40 dollars. Quote Link to comment Share on other sites More sharing options...
DefQon Posted June 29, 2015 Report Share Posted June 29, 2015 the output stage costs less and uses in production parts Any difference in sound vs 1968 or IXYS part output devices? Quote Link to comment Share on other sites More sharing options...
nopants Posted June 29, 2015 Report Share Posted June 29, 2015 I think there are some minor differences but not worth seeking out 1968s for the prices they command Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted June 29, 2015 Report Share Posted June 29, 2015 (edited) the fat supplies are now exactly the same size as the amp boards all the mounting holes in exactly the same place. 5.45 x 4.05 inches fits in the dissipante 2U box with the boards mounted horizontal with ample room for transformer, or 3U box with the boards mounted vertical, and even more room for the transformer. the skinny supplies are 3 x 6.5 inches which is a tougher fit in many boxes.

kevin gilmore Posted June 29, 2015 Report Share Posted June 29, 2015 with the fat power supply boards, definitely fits in this one http://www.ebay.com/itm/NEW-DIY-BZ4309-Full-Aluminum-Enclosure-power-amplifier-box-dual-heatsink-chassis-/261938269078?pt=LH_DefaultDomain_0&hash=item3cfcbccb96 iec hole already in the back panel Quote Link to comment Share on other sites More sharing options...
Earspeakers Posted June 29, 2015 Report Share Posted June 29, 2015 1. How many amp boards do you want. (one channel on each board, you need two amp boards for one complete amp.) 2 amps (4 each) 2. Which PS (dual, single skinny or single fat) and how many of them do you want. (you need at least one dual board or two single boards for one complete amp.) One dual and two single Thanks!

gepardcv Posted June 29, 2015 Report Share Posted June 29, 2015 With the latest matching board sizes, a horizontal mounting setup fits in a Galaxy 388 (not much room to spare on depth). Transformer in the middle, ideally it would be tall and skinny. With a creative setup, it might just be possible to use a Galaxy 288. The amp boards go on the top panel, possibly inverted, and the transformer sits beneath them. Then the transformer would have to be short and fat. Major problem with the Galaxy series is replacing the stock sides with true heatsinks. Has anyone ever asked Modushop about doing this?

nopants Posted June 29, 2015 Report Share Posted June 29, 2015 isn't that what the dissipante series is for Quote Link to comment Share on other sites More sharing options...
gepardcv Posted June 29, 2015 Report Share Posted June 29, 2015 The Dissipante line is much wider. 450mm, larger than any Galaxy case. Quote Link to comment Share on other sites More sharing options...
nopants Posted June 29, 2015 Report Share Posted June 29, 2015 you can always buy random heatsinks and mount them inside. that's what I was planning on doing if my case didn't meet proper sizes Quote Link to comment Share on other sites More sharing options...
sorenb Posted June 29, 2015 Report Share Posted June 29, 2015 @gepardcv: can you do a sketch showing your idea for chassie? I belive ModuShop do custom chassies ....if one buys five/ten ....it might be a low extra cost .... Quote Link to comment Share on other sites More sharing options...
