[Collins] crystals

[Dr. Gerald N. Johnson, electrical engineer]

Burghardt Radio
http://www.burghardt-amateur.com/Burghardt/HTML/main_frame.html has had
a number of Collins crystals on their used equipment list. Look at the
list as a text file.

Surplus Sales of Nebraska has had Collins Crystals (at believes them
made of diamonds and gold).

International Crystal Manufacturing of Oklahoma City makes good crystals
on order. There are other crystal makers that will make crystals in
single lots for better prices, and eventually they do make them work as
desired.
