[Central-Electronics] FS: MM-2 + RM-455 Scope

[Pete Ferrand]

Wanted something with a larger screen so I haven't used this MM-2 for a few years, although I've used it for most of the last 30 years.

It works fine and includes the RM-455 option to look at the waveform of the received signal in any receiver with a 455 MHz IF, or any IF between 450 and 500. There's also a 1kHz oscillator for transmitter testing, and high and low level inputs for trapezoid waveforms to check linearity.

All the original components are there as far as I know with the exception of the frequently troublesome C17, which has been replaced. The original coax sampling cable used for receive monitoring is not included, as I've never had one.

Here are photos I took last week:

You can pick it up in person and see it work if you're in the Chicago-Milwaukee area, only about 50 miles north of where it was built. If you wish it shipped, I'll be happy to remove the tubes, including the CRT, and ship them in a separate carton.

You can have this for $150 plus shipping and it will ship within a day or two of getting paid. Payment in cash, PayPal, or USPS money order. As-is, not returnable, not guaranteed.
