I realize this is a bit lower power than we usually discuss. But I may be
using this amplifier while experimenting with
some tetrodes. The plan is to use a signal generator and this amplifier as a
driver.
When I was initially testing the amplifier I had a 20 Watt 40db attenuator
between it and spectrum analyzer and
tracking generator. I was looking at the bandwidth without thinking much about
the actual output power at the time.
But when I turned it off and reached to move the attenuator, I burnt my
hand!!!. That was when I realized it was producing
more than 50 Watts during the test. Apparently it will produce several times
the power than advertised. I am interested in
finding out what protective devices it has with in, if any, for SWR, over
temperature, excessive current, etc.

I just received an Amplifier Research 15A250M3 amplifier which is in good
shape and working condition.
Checking to see if anyone has a manual or perhaps a schematic. Please email me
directly if you can help.
