Shielding for A-199 Spring Reverb

2009-12-31 by okmog

Hello World!

I want to buy a A-199 Spring Reverb module and have red that it must be placed as far as possible away from the PSU2 because of electromagnic coupling.

Has anyone of you already tried to shield the spring box with Mumetal? There are Mumetal coated folies available on ebay for a couple of euros with 0.1 mm thickness. Would 0.1 mm  be enough if the distance to the PSU2 would be about 30 cm, for example?

Mumetal (iron/nickel mixure) has a very high magnetic permeability and is very efficient for electromagnetic shielding.

I would appreciate any comments!
