I think the problem with the sliding trim is that the pots have bound up. I think it is because the lubricant has turned to glue. I was able to turn one of the pots with a screwdriver to free it up, but it still feels like a stick in the mud. I just ordered some Isopropyl Alcohol to clean them and see if I can get the radio back to working condition. If the cleaning doesn't work, then I will be looking for replacement pots to see if that route works.
I have a Futaba -T7UHP Super radio that both gimbals have frozen up. Probably the same problem.
Anyone else had any experience with these types of problems?
Thank you,
Ray

Fixed sliding trim vanguard infinity
Sliding trim pot was working but there was some kind of green glue that the plastic trim wheel and the brass pot stem had deteriorated. I cleaned that out , was able to slide the wheel back a little , then injected a little hot glue into the shaft of the pot and onto the wheel. Pressed it all back together quickly to dry. Worked good as new. Make sure the pot switch it level, compare it to a good pot for approximate angle on the switch.
