Recommendations needed for high quality valve bases

Post by RhythMick » Tue Aug 20, 2019 3:11 pm

The last valve bases I used looked great (black bakelite) but have screw in pins. I thought that was a benefit until I overtightened a couple after they kept coming loose.

So I'm after recommendations. Ideally copper or gold plated copper contacts, ceramic for low capacitance. What do you all use?

I use ceramic with gold platerd contacts normally. CMC Teflon for best (both from HFC). Not sure low capacitance is any issue at audio frequencies we are working with.
Resistance isn't futile it's V / I.

I thought that too when I read the orignal post, but didn't comment at the time. :D

I used ceramic for my scratch-built AM radio, but again plastic would have been plenty good enough I'm sure.
