Does anyone know what a pressure valve driven sound system is? How it works?

Well, it's certainly a real thing, but i can't find any explanation as to what it actually is or what it does.

Got it, they mean valves as in vacuum tubes. Valves is British for tubes

Here is a link to some pic's of the setup on the left of the OP

Lots of vacuum tubes involved...

Eats shoots and leaves.

The caption should read 'The fantastic Sounds & Pressure valve driven sound system'. Sounds & Pressure being the manufacturer.

Thanks UT, Lamp.
Rhianne, I tried searching for "Sounds & Pressure" but all that turned up was a record company, along with recordings they published.

My G-son was into reggae, but not my cuppa.

Here's a YouTube that (I think) has the sounds ( ck out the pic's at 0:00 and 2:01 )

Hooray fer da resourceful people. :rolleyes:

You're right, of course, Bruce. In my haste I misread the piece.

I hope I didn't lead you too far astray. My capitalization is still valid though and I hope it helps to show that 'valve' in the caption refers to what we called thermionic valves rather than pressure valves.

Sorry.

Not at all, Rhianne, the search I referred to was before I posted the picture. UT gave me the first clue that valve meant vacuum tube across the pond. Before that, being the son of a plumber, I was puzzled by that description, and wondering if the pressure valve control was some sort of pneumatic system like a pipe organ. So you see how far afield I was. :lol:
