Now that is a very good point! I knew they dropped less voltage, also the plate to cathode distance does look closer, but I had not linked that to its needing a smaller input cap. Thanks.

I am looking for those space age optional feet that go under those gold Bogen chassis. Need two sets if anyone has some for sale. Thanks!

Those and the right size case can be hard to find. They come up occasionally on ebay. Probably best to watch for a junker to take parts off of. That's what I do.
