This may help if your bad filter was made by Kokusai: It seems that the insertion loss is pretty much the same as the Collins mechanical filters of the same era, about 20 dB. Good luck, Jim Logic: Method used to arrive at the wrong conclusion, with confidence.? Murphy

To rough test whether the mechanical filter is working, jury rig a .01 Mfd
cap disc capacitor from filter input to filter output. If volume and noise perk
up, filter is probably bad.

Since I worked at Lafayette and also did the service for most of the NJ
stores for a number of years, when we started closing the stores as part of
bankruptcy proceedings, all the service parts, cannibalized equipment, and
anything else the stores didn't want and were going to throw it away, it all
came home with me. So, I probably have the largest collection of NOS Lafayette
parts that still exists today although I've been trying to work down the pile
for the last 40 years.

I don't recall, since I don't have the file folder and manual?in front
of me, whether we issued any service addenda on the HB-600.

The HB-600 was the "top-of-the-line' solid-state base transceiver we sold
in 1966. It was also called the "CB Commander" (one of the marketing guys came
up with that tag). Also had a? 5 stage "unique RF Noise Silencer". It sold
new for $220.

It made the front cover of the main 1966 Lafayette catalog.
