Yaesu FT-101 Repair Adventure

I put the second FT-101 E on the bench.  I put a hot set of tubes 2375/1200 in it, and neutralized the finals.  I let it warm up and measured the power output on all bands.  160 was low at 25 watts, but 80-15 meters was a good 100 watts.  I was able to get 100 watts on 11 and on the bottom of 10 meters.  On 29 Mhz, the power dropped down to 45 watts. I'll call that a success. Now I just have to align the transmit and receive frequencies and do some on the air testing.

I worked more on the FT-101 E today.  I installed a good set of tubes.  Actually they are a really hot set, reading 2400/1200 on the tube tester.  I neutralized them with the cold neutralization procedure. I got good output on 80, 40, 20, and 15 Meters.  The output on 10 meters was below 10 watts. This leads me to believe that something in the 10 meter tuning section needs to be adjusted. I will try putting a good set of tubes in the second FT-101 E and see if it does the exact same thing...
