I was just about to buy an A199 spring reverb when I decided to save 4hp of space and build my own.

The circuit is based on Roy Mallory's tech note and tone control, which is useful - a symmetrical cut/boost of bass and treble. The drive, recovery, tone and blend buffer take the four amps in a TL074.

The gain on the drive circuit is reduced quite a bit - R10 is 660R rather than 62R (it's R1 in Mallory's article), and the recovery circuit has a variable drive.

I put a couple of phono jacks on the back of my Doepfer case, so it's easy to plug in an external tank - a nice rich 6-spring 9EB2C1B (mainly because I built the circuit with the 8EB2C1B from a fender amp)

UPDATE: See revised schematic

Nice one!

And I also dig the plexi front plate.
Looks a bit like my OSC303.

Care to share how you built these?
I'm currently looking cheaper front plate alternatives than the usual Schaeffer job

Thanks!


Michael
