Having trouble with my FT-101Z. ?It has been on storage for about two years and was working before this. I have forgotten a lot about using it. ?During the Final Tuning procedure, the PO meter stays at 0 and does not move. The earlier tuning step, the IC meter behaves as expected. Any ideas? Thanks!
I had an FT-101B that had been in storage for over 20 years and fired it up. ?At first it worked and then didn’t. ?I found that there were two small diodes in the power supply that had died, actually physical broken. ?I replaced these and all was well. ?If I remember, I think they were in the enclosure that surrounds the output tubes.

Your description of the procedure you carried out is not too clear.? when you worked through the tuning/loading process did? the equipment respond as it should?? ie load giving an Increase in Ic followed by dip when adjusting tuning.? If so have you checked using another meter/device to see if there is any output irrespective of what the PO meter is showing???

With the switch on “IC” rotating “Drive” increases the reading as expected, and rotating “preselect” moves the needle as expected. When I switch to “PO” the needle goes to 0 and stays there. I have tried to attach a video for illustration.
Try exercising the switch, end to end, 20 times. If that helps give it 20 more. I find that any radio that has not been used regularly can benefit by exercising the switches. It wipes any oxide off the contacts.
