Title: Ultimation Fader Issues & Parts
Post by: skipburrows on August 04, 2026, 11:19:11 PM

Hi All,
Ive haven't been servicing an Ultimation Fader in a while and couldn't find this info.
Ive got some creeping faders and I know it's usually TR6 and TR7. Does anyone have a suitable replacement for those and also any other common causes of this fault?

Any info would be sooooo helpful...

Cheers Skip...

Hi Skip,

Give me a day or so, as an order of some alternates just arrived. I've got a few to fix and test to see if this replacement works.

Have you replaced the 1ohm current sense resistors?

Anthony.

Hey thanks Anthony..
No I haven’t yet, do you happen to recall the r designator for the resistor?
Appreciate your help…

Hi Skip,

R74 and R75, next to the motor drive transistors.
