I kind of stumbled across these VU meters. A true VU meter they are not I guess, they come with their own driver circuit and you can either have a low level signal or high level signal input.
Low level is preamp level output, no good in this instance as it will interfere with the amps input.
So I am using the high level input, straight from the speaker output, hence not a true VU reading. The VU meter driver board comes with two trimpots to adjust the meter deflection and I guess one can get close to a correct reading.
If you buy these as a kit, they come with a neat little fully encapsulated mini transformer, capable for 115 or 220V mains and with 6,9 & 12V tappings. It is small enough, as is the VU driver pcb, to fit inside the chassis.
I don't have an inside chassis shot yet, will post one once I get a chance to take a couple.
