rare birds: Dynacord Magic 370 spring reverb

this is a quite rare spring reverb built by Dynacord in the late 60s.
As minimal as it can possibly be: a black box with only a socket (input/output) and a gain level. Not even a power switch !
This particular unit was fully recapped and it sounds very nice, deep but quite bright for a spring reverb. Tank is a Accutronics one and electronics is only transistor based.
The pot is not a blend pot but a gain level. As you can hear you can get the unit to overdrive quite easily.
You need to set the unit as an aux to your mixing desk or soundcard. If you plug an instrument directly you will get wet sound only. In this demo it is connected to a RME babyface as an aux, and I used a Korg Mini Pops 120 (btw for sale here: https://www.ebay.com/itm/305744488287) and a Roland SH-101 as source materials
