Hi Tony,

Ok, I'm going to order some foils and also a Mumetal sheet with 0.5 mm thickness to do some experiments. I will let you know about the results as soon as possible. It could just take a while because I'm very bussy with learning for my final exams at the moment. So don't worry if I don't get in touch for a couple of weeks (worst case). ;)
I'm also very interested in getting best audio quality from this modular system.
So, the cable point is also very intersting. Thanks!

Have you or anybody else ever experienced EMC between Doepfer VCOs/LFOs and any filter modules, like it happens between the Steiner-VCO and Steiner-Filter (Frenquensteiner)

Also a happy new year!

Ollie

So if no one has actually used the mumetal foil for use with the reverb tank then experimentation is required (don't bother trying to do the calcs - too many unknowns). You could always do a double skin of the foil to increase the overall permeability and place the reverb as far away as you can get in the case. Also keeping any audio leads well away from magnetic components is worthe doing as screened cables don't help much with magnetic coupling. I'd be interested in how you get on - not so much from a synth point of view but more from a technical one as EMC is part of my day job.
