Just call me Mr. Sampler (and button question)

Geez, somehow I've ended up with three 1GHz sampling plug-ins.

The 1S1 is semi-working after my restoration attempt. I don't think it's fully happy with my Schottky GaAs subs...

Newly acquired is a 3S76 (2-chan!). Does anyone have a manual to sell or partly copy? Unfortunately, I think it needs a companion 3T77 to operate. Otherwise it's in good shape. Maybe I'll harvest some GaAs diodes from it! It has TWO connectors on the rear-panel in a "T" layout, whereas the scope bay just has one. Does this require a special mainframe, or is the second connector for testing or something? Or, is there a special cable or board that connects it to the 3t77?

Also new -- a 7S14! A real beauty. Two channel, with timebase. And..... It works :-) Mostly anyway. There's a bit of lumpy noise in one trace, and the buttons are all pretty sticky. So, any recommendations for cleaning and lubricating those 7000-series buttons? Oh, I wouldn't mind a manual for this one either. Guess it's time to build me some crude 50:1 or 100:1 passive probes! Oh, the delayed timebase ring is also missing. I've seen a picture of this - a rare example of really bad design from Tek as far as I can see. The pointer for the delayed setting is on a ring just like the main pointer, but smaller diameter. The 2 sweep knobs are normal concentric ones, and said ring is attached to the "upper" knob by a couple of fragile looking plastic ribs that travel down to it down the sides of the main knob. Seems to me that the first time you turned the MAIN knob a bit too violently, your fingers would tear off those ribs!

p.s., TekScopes continues to grow well. We have over 60 members now. Soon it will be my most populous group. We should throw a party or something.
