My 390a is clean as a pin. It is a Collins that went through a military depot refurbishment in 1986. I bought it off of Craigslist from a ham about 10 miles from my house. The problem it had was a bad cap in the IF module causing it to blow the B+ fuse. That was all it needed. I gave the fellow his asking price, $200.
The deals are still out there to be had. I never thought that I would be able to afford one. Just keep watching.
