Listen guys. The info's in here, you've just got to hunt, start building and then shout out when disaster strikes!
Built mine 4 years ago, and I'm old, so I've forgotten a lot since then, but to get you started here's a list of questions and answers, and other info I cobbled together after trawling through the posts. Might be useful. I've also attached a schematic I have in my files as well.
If you know where you can get a quad of 6s4a's from, don't tell anyone else, just let me know!!
You'd have to check through the posts for any significant changes over the past 4 years.
FWIW, I got my custom TX at a good price from Toroidy in Poland. It's worked a treat, but there are plenty of other places out there.
Good luck!
@matthew-levi Thought everyone was using the KGST with Pro output?
