[Boatanchors] Round Can Electrolytics

Guys, thanks for the many prompt replies and suggestions. The Tektronix 
2101 uses two of these 2000 uF, 50 V capacitors in the power supply.

The physical size is important as the cans have molded plastic insulator 
sleeves and there is very little clearance above the capacitor. 
Fortunately, this appears to be a standard-size can as it fits within 
the pull-down choices on the HayseedHamfest quote request form.

I have filed a quote request with HayseedHamfest. Great suggestion!
