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

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.

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?

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.

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

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!
