I found a nice selection of old film capacitors for my SCELBI cassette interface build at surplussales.com. Here is an image of what I ordered.

I tested all of these for capacitance, all have the correct value. I did not measure ESR. The most interesting of these are the TRW caps that came individually packaged in brown paper.

The West-caps are oval shaped, not perfect for the SCELBI cassette interface, but they will do, at least for now. I bought two versions of the .0068uF size, and will probably use the Mepco versions, since they are closer to the original yellow caps, than the TRW versions. My selection criteria, was to try to find something rated around 100V, with axial leads, and less then 1″ long.

I also found a great deal on Amphenol 78S11 type sockets at the same place. Since starting on this project, this deal, is the best price I’ve seen on this style socket. I bought enough to complete all the peripheral chassis that I plan to build. Here is my surplussales invoice, with parts numbers.

I have two more parts orders due to arrive this week, at which point I should be able to complete my 8B and start on the cassette interface.
