Hi everyone,
in the next few months, I am likely to start functionally restoring a pair of HK Citation 16As

they are the ones traded for a while back...

one is almost operational -- sounding OK at very, very low levels, but getting wonky with a little juice going -- indicitative methinks of failing capacitors...

the other is missing a fuse cap, and i haven't gotten to finding another to replace it...
(the other (semi-working) unit is a non-fused unit -- any benefit to retro-fitting a fuse assembly into the one without it already?)

anyhow, i've been reading a fair amount online about these amplifiers and what folks are doing to upgrade, etc...


installing new electrolytics is a must for both IMHO, but beyond that....
using hexfred diodes, replacing the ceramic caps with metal film or poly ones, etc

any thoughts from the membership here on a good (and cost effective) path to pursue?
