Hi all,
I've searched around but found various conflicting info so Im wondering if anyone can help with this particular application.
I have a small Sifam VU meter, the newer kinds with the 'retro' look, which also has 12v LED illumination. I've had to do some modification to get it to sit into the frame of an old VU meter to go in a preamp - I nearly lopped the two wires off the back to get them out of the way but instead cut a channel for them to sit into as I didn't originally intend to use them. Last night, since I thought I had damaged the wires, I quickly connected it up to a 9v battery to check if they were still working and they lit up nicely - and I actually like the look.
So I'd like to hook them up but the problem is that in terms of power, all I really have to work with is a spare 5.7v, 300mA tap on the transformer that was originally for a preamp valve heater (I moved it to a 6.3v with some others)
Would it be possible to utilise that tap to power the LEDs or am I just going to run into issues? I have come across various sources saying I can run LEDS on the AC, and some saying it needs to be rectified, but the difference in voltage makes me wonder whether it would work at all. Has anyone done it before?
Cheers!
