[HomeBrew] Any builders?

I do a lot of homebrewing from small HF-VHF-UHF SS projects to a KW tube amp 
and modulator for HF AM.

Another project is a hamband 160-10M dual conversion receiver using a mix of 
the best of the octal and loctal tubes and more modern circuit design and 
components. No SS except in the seperate power supply. Its a "what if" 
project to see how well a 1940's radio could really perform if the designs 
were readily available then. The circuit is somewhat complicated but 
construction is modular which will make test and changes fairly easy. 
Something I learned from working in military and commercial RF design for 
40+ years. With careful component selection and shopping the cost should be 
reasonable but not cheap.

However Ive found virtually nothing on this forum (and most others) beyond 
simple radios with as cheap as possible being the leading criteria. Finding 
other builders with similar interests to bounce ideas off of has been 
minimal to say the least.
