How to change vacuum tubes on the VPI 16.5 ?


Hello,

Anyone know what's the proper way to change the vacuum tube on the VPI 16.5? It looks pretty fragile so I don't want to cause any damage on to the assmbly. The manual was very brief and not detailed enough for step by step direction.

Thanks

It's simply a friction fit. Just pull it out firmly, jigglingly as needed to pull it loose. It is not fragile. Easiest to do if you pull out the tower the tube is mounted in so you can get a firm grip.
.
Straight pull should work. Be aware of a lockiing pin that may be there to keep for tube from twisting, but will not affect a straight pull.
.
Steady the black metal hub it plugs into with one hand and withdraw the plastic tube with the other. It's quite easy as long as you pull in the direction of the tube's long axis - don't apply any sideways or lifting force. You need to take it off now and then to clean the velvet and check its condition.

Of course, I DID misunderstand the title of your post when I first saw it and looked out of sheer curiosity!
