Hey-Hey!!!,
This amp is not all that hard. A volt meter will be all that's required to build the first one. You'll need to be able to adjust bias and adjust the front end g2 voltage with a resistor swap if you don't guess well. A measurement of the neutralization caps would be nice, but I'll offer some TFE insulated coax I have some experience with to anybody who wants to build.

I am going to lay it out, and drill most of the holes, but my wife is going to do the rest. There isn't too much that I or somebody else on the forum can't answer as far as detailed questions go. troubleshooting isn't going to be an issue for some complex NFB compensation issue because there isn't any in Galahad. It's all open loop. Which is why I specified 6k6 instead of 5k a-a load. Slightly better damping from the bigger a-a load.
cheers,
Douglas
