Here's a pic of one with the lid removed. It had a power switch and volume knob on the front (which was normally maxed and level controlled from the desk's monitor section):
And here are the rear connections:
Note the hideous Painton connectors used for input and output! Thankfully, it also had a B-gauge balanced jack socket for the input which is what we mostly used. The output cable had the nasty Painton connector at one end, and a female XLR at the other to plug into the speaker's male XLR.
Mains power to the amp was via a Cannon LNE mains-XLR. Secure... but it failed the finger test rules in the 1980s and became outlawed! (I still have one on my home-built Powertran DDL! ssshhh... :silent: )
HHHmmm? They had HH amplifiers in the Wigmore control room, for foldback. The BBC seem keen on them, or used to be.
