How to contact George Bischoff/Mark Porzilli

Does anyone know the best way to contact George Bischoff, former designer of Melos Audio products? Or, who might have schematic information for Melos products; specifically, the MA222 preamp?

Thanks in advance.

Hi Frogman,

Have you tried any of the contact info shown here?

It's a different Mark, but the same George.

Best regards,

Could very well be, but I'm not certain. Sometimes the last digit can indicate the number of zeroes which follow the first two digits, which would mean that it is 18 pf. That seems unlikely in this case, but as I say I'm not certain.

Voltage rating also needs to be considered in selection of a capacitor, of course, although if it is at the phono input that is most likely unimportant.

Hopefully George will respond with a more conclusive answer.

Best regards,
