"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)"
How are capacitor's polarity? (220nf, 22uf)
ReplyDeleteVery good!
ReplyDeletehi nice circuit. just to be sure. Those electrolytic are polarized so they have a plus and minus side. On the schematic, I see non-polarized symbols.
