Oh and you can see the relays with the top cover off. One is in the RF compartment and one is to the left of center.  They unplug.  You can remove the dust cover and then clean the contacts.

Another issue is  the Kokusai filters in the FT-101 series have a known failure mode. The internal foam gets gummy after a few years, and the filters stop working. The cure is to open up the filters, remove the gunk,  add  new foam, and you're good to go.

Here is  a link to  a web page that describes this problem:

Nice. Thank you for the link!  I have some dead filters in the junk pile.

PWEd,

I didn't know the FT-101 had a 455 khz I.F.

Its 3180.  I know because I have my SDR reciever plugged in and tuned there.

It's  3180 Khz, but that article is generic to all Kokusai filters.

But aren't the ones in the 101 crystal filters?

I'm reasonably sure (as Dave mentions) the repair of the filters you mention, Ed, is not for the crystal FT101 filters. 

Sounds like the Collins mechanical filters and their clones...
