Shielding Options for Dyno My Piano Pro EQ and Chorus in my 1973 88 key stage Rhodes

[DynoCzarus Rex]

So I recently purchased an original 1982 Dyno-My-Piano Pro EQ and chorus in a rack mount unit from a gentleman in Belgium. I'm now planning on having my technician, Tim Warneck of Retrolinear, remove the PCB from the rack mount and put it in my 1973 88 key stage model Fender Rhodes. I've attached some pictures below of the DMP unit. So after the restoration is done I'll have an awesome sounding, brand new Dyno-My-Piano that will able to get something close to that coveted Leeds E-model tone. One thing that I noticed about the unit is that there is no copper shielding around it. This will be my first Dyno and I've heard they are kind of notorious for high frequency hiss. What kind of copper shielding options might be best at reducing the noise and at the same time not cost that much? Any advice would be greatly appreciated.

I don't know these units, but shielding is only really good for reducing EM/RF interference. The HF hiss associated with it could well be inherent in the electronics and won't be reduced by shielding. I'm sure someone with knowledge of these will be able to shed more light.

That's a good point that I had forgotten about. So you're saying the shielding was meant to keep other keyboards from interfering with the high frequency hiss of the Dyno preamp. I guess the next step would be to maybe look at noise reduction options. I have experimented with a noise reduction plug-in from Waves but it's pretty limited in what it can do. Are there any hardware noise reduction units that are worth looking into?

What I meant was shielding is mostly used (e.g. in guitars or cables) where there is susceptability to EM/RF interference via airbourne, proximity or mains based signals. Whereas HF hiss is generally an inherent byproduct of cheap, old or inferior electronics and nothing to do with external interference. So shielding may not help at all (depending where its coming from). I'd wait until you've tried it to see if its noisy, then figure out what's causing the noise, then find a solution. Shielding is always easy to do after the event. There's a few software noise reduction options (izotope RX5), not sure about hardware. The best option is often to live with it as analog character
