Interesting. My 101Z suddenly became 'deaf' some time ago.? After a lot of investigion work I came to the conclusion that? the first RF Amp device had likely failed.? I am a little reluctant to start desoldering etc as the rig is in 42 years old original untouched condition.? Were yuu able to source a genuing 3SK51 (or use an equivalent?) I cannot find one on internet but I understand that a 40673 will work.? Any frther information on your rix would be appreciated.? Thanks Al GM4ENF.

My 101zd was about 10db down on rx. I went down the troubleshooting road and cleaned all the relays I could find and checked the lamp fuse.?
Wound up changing the first rf amp and it came back to life.?
