Hey all!
Got a working RM using the Mouser transformer part #42TM018. This
differs from Mike Marsh's RM in that he used a micro transformer with
a lower secondary impedance (2K). Sounds prety much the same. I'm
following mine with a non-inverting amp and buffer arrangement using
a TL072 opamp. This will provide the makeup voltage gain of 2.5 -
though I'll probably go a tad higher and just use standard value
resistors for the amp.
Time to etch a pcb and drill a front panel as this definately has a
home in my synth! Let me remind you that I'll happily send out
quartets of reasonably matched germanium diodes to all who ask.
Enjoy!
