Right, I was going to see if I could find a ribbon connector for the board in which some of the pins lined up with 3-4 channels of buss wire and just clip any pins in between the active connections. Off-the-shelf ribbon cable is pretty cheap so it wouldn't matter that i was using only a fraction of the connections.

Anyone know how I could replace the vu bulbs on my system 8 with LEDs. I tired of replacing bulbs I think the LEDs would be a permanent fix maybe.

Thanks so much for the thread.

Im looking to buy a system 8 and im sure this thread will be a god send.

Its also something on my list of things to modify in mine. Probably looking at a small PCB with a number of orange or yellow surface mount LEDs and some sort of current limit.

There is a suitable FC series cap with a 25V rating Digi-Key - P11212-ND (Manufacturer - EEA-FC1E100)

Did the channels with the WIMA caps make a difference?

considering joining the system-8 party myself nd am trying to familiarise myself with it all... i notice that your board appeared to have no eq-cut switch next to the gain knob... doesn't that make it a mk1 ? did it have 90mm or 100mm faders?

Allen & Heath actually have an official LED modification kit for the GL and ML series mixer VU meters - consisting of a small PCB on which a pair of yellow 'tombstone' shaped LED's are mounted together with a dropper resistor.

It will probably be suitable for most of the VU meter movements found on popular mixers.

Contact A&H directly or your nearest service centre for more information.

I have modified a few mixer VU meters - and depending on the type and how they are mounted, it is possible to illuminate them very well from the edge, or even the rear - which has the advantage that you don't need to open the meter and risk damage to the delicate movement.......

Modern LED's are available in a variety of styles - and incredibly bright types are easily available now. Many might agree though - that the use of blue LED's ought to be against the law!

[Jim Williams]

Yellow LED's look bad. I use either pure white (with a slight bluish tint, but modern looking) or special incandesent colored white LED's that look like bulbs.

have them. I sand them to difuse the light, they look great.
