 I'm getting ready to start working on an R-274 that I picked up this past
fall. A quick survey of the internals shows that many of the capacitors show
evidence of decay (cracking) and the resistors I did a quick measurements on
are out of tolerance.
 
First order of business will be a complete disassembly and cleaning (it is
pretty dirty and smelly.....). Then replace any out of spec parts,
reassemble and see how it plays. It is mostly original from what I can tell
with the exception of a replacement 455kc crystal.
 
Looking for advice from those who have "been there, done that" with one of
these radios before. What should I look out for - what parts are typical
troublemakers, etc.......
 
Just finished an overhaul on an R-390A that came out well and have been
tinkering with these boat anchors for many years so I have some experience
and a bunch of test equipment. Never been inside one if these so looking for
advice.
