Picture is of one of them - both are in similar condition.

This is a part from a very nice Collins 30S-1 Linear Power Amplifier.  We purchased this unit because we thought it came from the same estate that we are processing all of our Engineering Equipment from.  It is not from the same estate, but it is better than the one described in our inventory notes from the estate.

We do not have equipment to test the amplifier, but we powered it on and are professionally testing most of the components, including sending the Eimac Tetrode tube to have it tested by Richardson Electronics.
