[R-390] Question from a Newbie

[Tisha Hayes]

'I just recently obtained 3 R-390A and 1 R-390 and am now starting to work
on one of them.  Don't have any prior experience with these beauties.

It just occurs to me that I haven't seen any reference to extender cables.
 Are there such things out there?  I assume they would not be difficult to
build if plugs were available.  Are plugs available?

Thanks,
John

John, Welcome to our rather dysfunctional family who still thinks tubes are
"cool". You may see us at hamfests, we usually are really twitchy from doing
the "tongue test" to see how much AC ripple is on the B+ supply.

There are some folks who may use a tube extender socket but I many of us
will test the radio "in situ". You have an advantage with the R-390A in that
once you get one radio working in great shape you can swap modules across to
isolate problems.

Of all of the things that may have ever been wrong with the R-390(A) radios
or the possible ways of upgrading/ updating/ painting/ sanding or bleeding
has been done by someone on this list.

Many folks also carry rather "substantial" collections and usually if you
are hard up for a part there is someone who will take pity upon you to help
out.
