I built another GI-7B amp - this one for Six Meters. It seems to work pretty well although not putting out the power like the HF amp. That might be due to the smaller power transformer or it could be something I screwed up.
Here's a picture of the guts.

This is all self contained and fits into the case from an old Clegg 22er. I think I need a bigger fan and I definely need a bigger meter - this 300ma meter pins when tuning up.
about 20 watts drive gives about 250 watts out. I have yet to test it on the air to see if it passes the W1JR test. Those in New England know what that means.
Anyway, it's been a fun project.
