Thanks. I managed to finally locate the crossover circuit diagram as that seems the only diagram in existence!

The amplifier boards are loosely based on M20's, so was able to work my way around the circuit and resurrect the customer's speakers.

It's amazing how good the M100's sounded after they'd been repaired and re-capped...

If anyone has any problems with their M100's please drop me a PM and I'll see if I can help.

Cheers,

Steve
