Thank you Carl
Yes, I'm looking forward to Jeff's layout as well - I've got a good compartment with pretty lengthy heatsinks - great box for such a monster amplifier
I think an AB comparison with the Slewmaster/Kypton-ND will be interesting. I hope Ostripper reappears soon with an integrated board design.
Thank you Carl

You need to stop cranking out new designs long enough for me to get my anodizing supply finished. I need to get some chassis finished for a few of these, but there's too many cool looking amps that look like more fun to build.
Jeff,
When you send out for PCBs on this one please order a channel pair for me! I will be sure to pay you for them.

Haha))) OK, I think I will more or less stop for now with the new stuff and work for a while on some layout optimisations, cool combinations, SMD options. "Productising" the existing developments. I'm also going to build the VERTICAL + NS-OPS in a good compartment - will take some time
Your layout looks very good for that build 
When you have done this please share the circuit.You need to stop cranking out new designs long enough for me to get my anodizing supply finished. I need to get some chassis finished for a few of these, but there's too many cool looking amps that look like more fun to build.
Enclosures is something difficult here.
Yes,i have try this in the past,using a variable power supply.
I know that a constant current power supply is necessary.
I used Elvee's basic design, but interfaced it with an Arduino with a little help from Valery for the coding. I will be posting my finished product.

I have cheched - even at +/-75V dissipation barely exceeds 1W. That's why I use two 1W resistors in parallel. They will get pretty warm, but still having a good reserve.
At +/-70V - no problem. In this case zeners will get around 8mA, which is ok for them to work properly. Dissipation falls down to 0.7W, which is always good.
