Am-Comm Penetrator 1000 Base Linear Amplifier

The SD1076 transistor dates from the late 1970s. A data sheet has never been posted online where I could find it.

But here is a catalog list of some sort. Says it's rated for 70 Watts output, with 13.5 db power gain. That's a gain factor of about twenty to one. Should suggest that a single transistor needs about 3.5 Watts drive to get 70 Watts out.

Does say it's meant for a 12-Volt power supply. Might check inside this one to see if it's "cheating" with a high power supply voltage.

This thing is really old. If it has survived this long with original transistors, that would really be some performance record.
