I realize this is a 4 year old thread. Were you ever to fix the VCO2 problem? I have my Dad's old TS-440 and have been slowly trying to get it going again. Already fixed the Band Pass Filter diodes and Cleaned the VCO5. Now the next thing to fix is the VCO2. I only have 0.97 vdc on the T9 test point which should be 6.4 vdc. No changed when adjusting the T9 coil. Still looking for the failed component. Thanks to anyone who has an idea. Not much web info on the VCO #2 for this radio.
