mwl168 Posted February 15, 2015 Report Share Posted February 15, 2015 (edited) Thanks Birgir. I am planning to start a mini KGSSHV boards GB. I'll be using the kgsshv16mini.zip for the amp board and kgsshvpsminifinalstn9360.zip for the PSU. Can you confirm if the following board sizes are correct? Thanks! kgsshvampv16mini: 183mm x 99mm kgsshvpsminifinalstn9360: 176mm x 167mm Edited February 17, 2015 by mwl168 Quote Link to comment Share on other sites More sharing options...
johnwmclean Posted February 18, 2015 Report Share Posted February 18, 2015 I noted an error on the silkscreen for kgsshvpsminifinalstn9360.zip file, the stated STN9360 should be KSA1156. Quote Link to comment Share on other sites More sharing options...
mwl168 Posted February 18, 2015 Report Share Posted February 18, 2015 I think the kgsshvpsminifinalstn9360 board can accommodate both KSA1156 and STN9360. The STN9360 will need to be mounted vertically while observing the pin out specification. See Kevin's post #4014 in this thread. Although I can use additional clarification about the use of 270V zener with KSA1156. It would be great too if someone can share some insights of the pro and con between the choice of the two devices. Quote Link to comment Share on other sites More sharing options...
Earspeakers Posted February 18, 2015 Report Share Posted February 18, 2015 Anybody try with the amp boards vertical? I have a chassis idea/approach that would utilize this, and it would seem to allow greater airflow over the sinks if anything. Quote Link to comment Share on other sites More sharing options...
nopants Posted February 18, 2015 Report Share Posted February 18, 2015 Anyone have an appropriate part number for the servo cap? Most of the parts I've bought are too wide, and the leads are too thick. I'm making an order to Mouser for some BH stuff but I figured I'd polish this off while I'm at it.

I don't know if you would parallel the device to limit it to 270V or put it in series with the collector or emitter? Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted February 20, 2015 Author Report Share Posted February 20, 2015 the ksa1156 is a 400 volt device. The 270V zener across it prevents it from blowing up on turn on. You can leave the zener there for the 600v part Quote Link to comment Share on other sites More sharing options...
Pars Posted February 20, 2015 Report Share Posted February 20, 2015 Thanks Kevin. That is what I figured. Quote Link to comment Share on other sites More sharing options...
Laowei Posted February 21, 2015 Report Share Posted February 21, 2015 Has this PCB for the carbon been validated to build copies? http://gilmore.chem.northwestern.edu/boards/kgsshvcarbonv1.zip Quote Link to comment Share on other sites More sharing options...
UFN Posted February 21, 2015 Report Share Posted February 21, 2015 Has this PCB for the carbon been validated to build copies? http://gilmore.chem.northwestern.edu/boards/kgsshvcarbonv1.zip I hope so, because I just received mine //UFN PS: Looking at heat sink options for the Carbon at the moment - how much do I actually need?

spritzer Posted February 21, 2015 Report Share Posted February 21, 2015 (edited) Nope, no carbon files have been tested. You have been warned as that one was a rush job. Current is fixed so the voltage is the variable. I won't be going over 400V with this one, same as the Megatron.

gepardcv Posted February 22, 2015 Report Share Posted February 22, 2015 If anyone wants some recent KGSSHV boards, I have two extra sets for the on-board heatsink version. kgsshvamp14mini.zip and almost kgsshvpsminifinal.zip (except it's version 1.0, not 1.1 — I didn't check closely what changed here between the previous final version and the current final version ). Please PM me if you're interested. Quote Link to comment Share on other sites More sharing options...
nopants Posted February 22, 2015 Report Share Posted February 22, 2015 in the kgsshv psu can I get away with a 2W rating for the 15 ohm sense resistors? I was going to use some 3W-rated pulls from a busted supply but there's some soot and possibly cracking on the bodies Quote Link to comment Share on other sites More sharing options...
spritzer Posted February 22, 2015 Report Share Posted February 22, 2015 Thermal ratings on resistors are a crapshoot at best (hello Mills!!) so a 2W might work but it also might not. Try it and then measure them... Quote Link to comment Share on other sites More sharing options...
DefQon Posted February 23, 2015 Report Share Posted February 23, 2015 Glad I'm no the only who has had trouble with Mills resistors and there blotchy thermal heat dissipation ratings. Quote Link to comment Share on other sites More sharing options...

mwl168 Posted February 24, 2015 Report Share Posted February 24, 2015 (edited) looking very nice reminds me of something but i can't remember what it is It reminds me of Goldmund preamps. Also the Spectral preamps made in the 90's (I think). Never heard the Spectral but a couple of Goldmund preamps I listened to were very nice sounding gears. Nice build. It looks very slim. Does it use shorter heatsinks or it's an optical illusion? Some interior photos would be great! Edited February 24, 2015 by mwl168 Quote Link to comment Share on other sites More sharing options...
