You're lucky, you have a good channel to look at. With a scope or signal
tracer, compare the L chan to the R chan, going from input to output,
with an audio signal into both channels, until they don't match. Ken

Needed: Help Diagnosing Weak R Channel on HK Citation 14 Tuner

I have a Harman Kardon Citation Fourteen Tuner... the R channel only
puts out a very weak audio.. can hear music, but only high freq and
very faint.. If anyone can give me some ideas on how and where to try
and diagnose what's causing weak R channel, would greatly appreciate..
L channel is fine and strong.

Also, pulled out the 2 blown lamps behind meters.. part # CM 1813 but
no values... anyone know values of replacement bayonet type bulbs?

Thanks for any help.. Greg in Chapel Hill, NC

You can get that same signal by tuning to a mono signal or switching the tuner
to mono.

One "obvious" thing to check... Check your cable, and check the connections of
the right-channel jack to the board.
