[R-390] Off Topic HRO Rebuild

[Tom Frobase]

I was at the Belton Hamfest about a year ago and bought a couple of 
really rough HRO receivers.  I donated one of the to the Battle ship 
Texas and kept the other.  The one I kept was really bad, it made no 
sense to try and get it running it was just too ugly. 

Over the holidays I decided to take the time as a "labor of love" and 
gut the radio and rebuild it.  I was surprised it took over 4 hours to 
disassemble the radio and clean the solder off of the sockets and 
terminal strips.  I took approximately 50 digital pictures to aid in the 
rewiring of the radio. The main capacitor also had to be completely 
disassembled as well.  The chassis was stripped, sandblasted and 
repainted.  The IF and BFO cans were disassembled and cleaned.  All 
existing mica caps were replaced.  I used modern resistors and caps 
saving lots of space.  I used a medium sized ultrasonic cleaner for most 
of the cleaning using a solution of sudsy ammonia, it did wonders for 
the aluminum parts and made the ceramic come out pure white.  It took 
about 12 hours to rewire the radio Other than a broken internal wire on 
an IF can, it essentially worked the first time.  I have an output 
transformer ordered from Fair radio but else than that "IT IS ALIVE!!!"

Here is a link to some pictures, they should be speak for themselves
