[TenTec] OMNI VI replacement encoder

[John Oglesby]

Interestingly on my OMNI VI+ the factory installed encoder was an 
OAK-GRIGSBY 90Q125-02-00245 with a date code of 12/08/97.  It has a 
similar pin configuration to the Bourns replacement that Curtis found, 
but is a different form factor.

I replaced the original encoder today with one of the Bourns' encoders 
from ebay and it is working very nicely.  It is an easy replacement - 
four screws to take off the case and four screws to drop the front panel 
assembly then remove the old encoder and put in the new one.  Very simple.

If you check the Bourns EN series data sheet, you'll find that the only differences are that the Ebay one has a ball-bearing shaft and it has radially oriented connector pins instead of axially oriented (both, I think are better for this application). It's the same 128 ppr, 1/4" shaft encoder and it is working great in my rig.

>> I thought I'd pass this along: My Omni VI wouldn't change frequency so I subbed the RIT encoder and confirmed a bad encoder. I found one on Ebay that not only was close but better than stock (it's got a ball-bearing shaft instead of the stock one with a bushing only). Not only is it working better, it's only $21 shipped! Needless to say but I bought another one today to have on hand. Here it is:
