The main tuning knob on my older Ten-Tec transceiver will not turn; can I add a light lubricant or solvent to the grease and free the PTO?
No, if a light lubricant or solvent is added to the grease and the grease is thinned or removed, the PTO may turn but could have excessive drift or frequency jump. An incorrect type of lubricant or solvent could damage the plastic or electronic parts of the PTO.
If the PTO is stuck it must be disassembled, cleaned and mechanically rebuilt. A PTO rebuild kit is available from Ten-Tec Service. The PTO kit contains all the necessary replacement parts needed to rebuild the PTO. The kit also contains complete step by step instructions and correct grease.
