I built my KGSS on perf board I found at Mouser. However, like others have said, it can be quite "entertaining"

  Mine went fairly smoothly, but I have over 28 years repairing TV's with HV circuits, and am quite comfortable working with HV. You have to be really careful with detail and component spacing, or arcing can occur (none with mine). I also opted to build the original power supply with a few small changes vs the PS for the Blue Hawaii. This simple regulated PS works perfectly. However, if you chose to build it using the schematic on Headwise, DO NOT use a transformer with those specs. An 800VAC CT transformer is way too big voltage wise. Also, the current 2SA1968 that's available today does not hold up on the -350V rail. PM me if you decide to brave it and have any questions. Also, the eXStata is a decent stat amp, but I don't believe boards are available anymore. It's easy to build if you could get boards. I'm also sure it would be much easier to build on perf vs a KGSS, IMHO. Good Luck!

Forgot to mention that my KGSS cost me around $400 in parts to build, minus any casing.

The Exstata SS is pretty easy to do on a perfboard but if you don't know how to handle HV and are comfortable working around it then stay far away from it.

Okay, I'm going to ask about good procedure when working with HV. Keep one hand behind your back, operate on a non conductive surface to ensure you aren't grounded, use insulated tools, and make sure the transformers and such are in working order before attaching anything else so you dont fry your components?
