I just got my Tel-Ray Add-n-echo working and it sounds amazing. It is an "oil-can" type echo unit, which uses a rotating can of conductive fluid with tape heads inside to create the delay effect.
It wasn't working when I first got it, had to replace the 7199 tube, lube the motor, and add some "magic fluid" to the can. Apparently the "correct" fluid is hard to find and you have to buy it from these guys (moderators of the Oilcan Addicts Forum) for $50 for a little bottle. I dug a little deeper and read that DOT4 brake fluid has similar properties so I figured what the heck and added a bit less than a teaspoonful of Prestone DOT 4 I had at the garage and it worked!
Here's the insides:

Note that in this picture I have detached the motor/oilcan unit and turned it on it's side to access the inside of the can. The motor/flywheel is hidden behind the can.
Here are some pics:

It sounds like the Ventures when plucking muted strings, or you can tweak the knobs and get crazy sci-fi sounding warbly noises and swells and when it feeds back it's crazy. One cool thing is that the TelRay acts as a tube pre-amp when the effect is turned off (footswitch) so I can use it in front of one of my low-power amps as an additional gain stage.
