Here's an interesting Home Brew item....

This is a three tube 28 MHz to 220 MHz linear converter built on a
piece of PC Board stock. It uses three tubes, a 6AN8 and 2 6360s.
Looks like it's all there but there is a bit of work that remains to
be done. The schematics are most likely from an ARRL Handbook from
the 60s or 70s. It is very well constructed using ceramic tube
sockets and trimmer caps.

I am asking $30.00 plus postage for it. If interested please reply by
e-mail.
