I am looking for some information on the P2620 kit which is a giant mains output VU meter. (also known as K2620).
I built this kit some time ago and have been using it, with great effect, with my mobile disco.
Unfortunately I have a problem with the kit and no longer have the wiring diagram.
My problem is that with no sound signal present all the output channels are lit.
I have removed all the triacs and re-fitted a new one which still ights so I think they are being driven rather than having a short.
If i remove the small I.c. tl081 there is no mains output. I think this is a signal amp for the sound input which i guess could make sense.
Anyhoo, I wonder if anyone has any info for this kit.
Thanks. Mark ( a forum virgin )
P.s. I still have 3 other kits (the 7 channel eprom driven light computer, the 4 channel chaser and the 3 channel sound to light kits which i use regularly. Thanks Velleman
