Have you considered changing the knobs with ones that have a set screw?
Is the head of the shaft designed with a slit? If so, you may be able to spread it out carefully to a larger diameter so that the knobs fit tighter.
Levinson 326S Volume Knob Loose
I just purchased a used 326S preamp and noticed that the knobs for input select and volume are loose and can be easily pulled off. It was cold when it was delivered so I thought when it warmed up it would be better which it did help a little bit, input select is now snug, but the volume knob is still pretty loose enough to slip on the main axle. I also noticed that the brass axle drum is shallower for the volume than for the input select, is this normal?
Anyone else experience this?
Thanks
There is a brass drum attached to the main shaft and a spring loaded ball bearing that should apply pressure to the inside of the knob so maybe it has just lost its rebound but wonder how to fix. I suppose could put some electrical tape on the inside of the knob to make up for the difference but don’t like cobbled solutions. |
agbrace OP: I know what you mean. I like to fix things properly myself. Maybe the spring-loaded bearing is seized? Lubricate? There is always epoxy (but permanent) or while plumber's tape. Better option than electrical tape.Personally, I would see if the entire pod is available and I would install a new one. Can't be much more difficult than some patience, some screws, desoldering and soldering. |
@ellajeanelle Thanks, the plumber's teflon tape was a great idea. A single strip around the brass drum allowed the knob to slide on smooth without too much force and holds it perfectly. |
agbrace OP: Nice!
