TS-440 DOT problem.

Kenwood used some potting compound to seal/ stabilize the vco's on the 440S,

This is a base/mobile rig so Kenwood thought the vco would need physical stabilized by use of a compound. worked great.

Then age ( as it always does) deteriorated the compound and it became corrosive thus the need to remove the compound and replace/rebuild the vco.

Parts are hard to find now to rebuild the vco and many repair techs will not work on the old 440's if they have a vco dot problem.

The 430 are ok. known issues on them are documented all over the net.

the TS 450 is a great rig also.
