Need zenith roundie convergence board

[bgadow]

How well do the coils interchange? I've swapped the pots off of different brands of convergence boards but maybe you need more precision with the coils? Get the part numbers off the Sams-Moyers, or maybe even one of us, may have them on the shelf.

Your problem might be bad seleniums? Fairly easy to fix that.

If a slug jams heat the coil up with a hair dryer or heat gun. I ran into this recently with the efficiency coil on my CTC-5. One minute with a cheap hair dryer and it worked as smooth as new.
