"Up for sale is a very rare and unique piece of test-equipment-cum-modular-synth, the Bradley Telecom Model 2A Jitter & Hit Synthesizer. This was made from the late 70's to the early 80's for those working on phone lines, and is basically an analog synth/noise generator that is designed to mimic common problems found in phone lines (noise, clicks, etc.) It has a sine oscillator, a modulation oscillator, various other modulation sources, an envelope that's more or less Attack/Decay with variable time ranges, a noise generator, etc. You can patch it using Banana cables (which i did with success with my Serge system) and features a proper 1/4" input & output.

It's quirky, glitchy & weird. RJd2 is allegedly a fan & user of several of these, and there's some videos of some in action with a quick Googling."

Bradley Telcom Jitter and Hit Synthesizer Model 2A

via this auction

"RADLEY TELCOM JITTER and HIT SYNTHESIZER model 2A with FREQUENCY TRANSLATION AND HARMONIC DISTORTION MODULE model 2B

This is a rare, vintage jitter and hit synthesizer for producing far out sounds and noises. This was built for telcom equipment testing but is now used in electronic music. It can both generate tones, as well as process or modulate any incoming signal(great fun on drums). the harmonic distortion unit on the top half is a partly-separate unit."

Note one recently came up for auction captured here. It's actually test equipment and not a synth in the classic sense. Details from the flickr set:

"photos of a (somewhat rare?) early synthesizer. thought this was an interesting unit, so i figured id take some pics and share. dave from the audities foundation has pegged this as a telephone testing device. there is no date of manufacture, and i couldnt find any documentation on this-my guess is 1969-75, based on the construct and fonts, but who knows? SN 772.

it can both generate tones, as well as process or modulate any incoming signal(great fun on drums). the harmonic distortion unit on the top half is a partly-separate unit; the 2nd and 3rd harmonic distortion can only be accessed through the upper level of pin inputs."
