Lightshow question

My lightshow shines super bright on 3 out of 9 of the bulbs. The other 6 light up - but are very dim. Changing the bulbs around proves the bulbs are all OK. I read that ............"Inside, on the board, were three individual mini pots, sesitivity for each of the three color channels."........... I'm no electrician - but I can't see any mini pots?? anybody got any ideas on this one??

Graham, you may actually have to look for a hole on the board through which the pot adjustment screw can be accessed, the pot being mounted on the back of the board. I'll go back and look at your pictures in the other thread and see if I can spot any.

Another thought: mine was strong (aka bright) on the yellow, and dim on the blue. In other words, bright on 3 sockets and dim on 3 sockets with the others being somewhere in between. Power wasn't right - when fixed everything was nice and bright. I assume you have a meter? Are you getting the right output on that transformer?

I thought those pots adjusted the frequency that the colors would respond to, not brightness sensitivity...

John - you credit me with far too much technical knowledge! I just plug it in and strum away! I was more interested to see what the score was with these sensitivity pots? I'm looking to see if I can find a transformer over here in the UK that will do the job. Failing that could I buy one from you?

Thanks guys, keep that good info coming.

Be careful with transformers Graham, 'cos according to the TV advert. they are "Robots in disguise"
