Sorry for asking but I don’t suppose there’s any way you’d consider taking gut shots of the Solid State Reverb & Echo 600 for me would you? Been looking for photos for years.

Either way, great collection

Well I don’t need them butchered as such, but a couple of photos of the PCBs would be appreciated if you do change your mind in the future.

There’s no Echo 600 schematic in existence and it uses 3 x MN3005 from the one gut shot I have seen so must be different in design other than additional parameters to the Deluxe memory man to some degree at least and while I do have one for the reverb, I have no idea how accurate it is.

So as a vintage EHX enthusiast i’d be interested to have some concrete information on the circuit designs for my self, the DIY community and for any units that might cross my path for repair

It certainly would be cool to find some units for spares or repairs, if you find any, keep me in mind for getting the repairs done if i’m correct you’re in France so being in the UK i’m a lot closer than some of the major EHX repairers in the US.
