Subject: [AMRadio] on cleaning tube sockets and pins
Date: Sun, 26 Jan 2003 13:34:58 -0800 (PST)
I am ressurecting a Viking Invader 2000. It is coming
back to life reasonably well. Almost ready to pop in
the 4-400's and burn the house down.
I had to replace a rectifier and a couple of
electrolytics in the exciter supply.
The balance of the orignal electrolytics all formed
such that each draws no more than 2 MA @ 450 DC. Not
bad for 40 year old firecrackers!
Some crud managed to get in the threads of a couple of
the padders in the driver tank. I have cleaned the
threads of the trimmers and have good output in the
various modes. Sure is a lot easier than adjusting a
phasing rig!
Dirt or oxidation had gotten into a couple of tube
sockets and this made the output unstable.
Eventually, alignment of the various stages yielded
good results - I just had to periodically wiggle a
mixer tube.
Thus, the most trouble I am having is related to
intermittant connections on the various 7 & 9 pin
tubes.
Any body have any "sure fire" tricks on cleaning tube
sockets and pins of minature tubes?
