I bought a Lindhof ringmodulator DIY-kit on ebay about two months ago. Easy to do and compatible with Doepfer, as it runs with 12V although it is based on the Formant Pro, which usually runs with 15V.
It sounds okay, but different than the A-114. The only problem is that if only one signal is patched into the ringmodulator, it is still audible on the output. But I think it might be my fault, as I didn´t really manage to calibrate the PCB (that one is my first powered DIY-module, I must admit..).
