Bringing Aims amp back to life

New to this site. Have been an owner of an Aims Eclipsor 4 X 10 since '73'. Haven't used for many years in process of re-capping and fireing it back up. Have a question though, would anyone know what the resistance of the photocell in the tremelo circuit is. Need to replace it, the leads have pulled out of it. Thanks in advance!

I could not find a schematic for the Eclipsor, but I found this: aims personalized eclpsor - Music Electronics Forum (music-electronics-forum.com)

The optocoupler circuit looks pretty similar to the intensity section of a AB763 Fender Tremolo circuit. The Aims uses a 100K pot for the intensity and the Fender uses a 50K pot.

It's pretty easy to find the Fender part and I believe it crosses to VTL5C3/2

Whether this is the right part or a suitable sub, I can't say.

Good Luck!
 
Was just going to replace the photocell. Just need an idea what the resistance is when there is light on the sensor. May need to experiment. It is 99% the same as the dual 12 schematic. Just need to have some throw a meter on that cell with light on it. Thanks
