I have accumulated approximately 9 of various models of Chaparral Monterey satellite receivers that incorporate control of dish position via 36v motors. First year of manufacture was around 1989. This model line was "the most upgradable and upgraded satellite receiver in the world for 10 years". My newest was made in 1994 or 1995. I still have 2 of the top of USA line 95 models in constant use. Only 2 lesser models were functional last I checked several years ago, but because of missing features I'd hate to have to substitute either when something goes wrong again in those in current use. I tried shopping for newer dish positioners, since positioning is the main thing they're good for any more, but the selection has dwindled to about 2, both poorly featured by comparison to these antiques, and neither of which is suitable for use in the same room at the same time as a second, as I need.
They are among the hottest running such devices I ever encountered. Each uses somewhere around 39KWH/month. Besides normal use, I use them to accelerate curing of epoxy, and dry washed remote button pads.
Each has two big transformers, probably 10 lbs. for them alone at least, maybe more than 12. Their digital boards each incorporate 3 different CPUs, among which one is an 8088-2.
I replaced the largest power supply caps in several quite some years ago as they began misbehaving, before I knew more than a token about selecting replacement caps. Many of the big 35V and 25V 4700, 3300 and 2200s were oozing, some quite badly, so I changed all 3 on any of their power supplies I worked on at all. Probably on most I worked on I changed all their 3300uF 35Vs as well, as IIRC at least some of those were leaking too.
I never succeeded getting a third 95 model resurrected, and now I want to try again, so that it can be substituted for either of the two now in use in order that I can check them over, including looking to see if any more leaking has developed, and check if prior leaking was properly cleaned up before any gets a change to cause uncorrectable trouble.
Every cap in them is a Nichicon radial, series PF, PR, VR or VX. The power supply has 20. The model 95 digital board has 45. The A/V sections have too many to count, probably upwards of 150 across multiple boards. I only want to focus on the power supply to start with, then if that's not enough, clean and recap the digital board.
Datasheets I found for only PR, VX and VR, and the VX I did find turned out to be for axials. So, will someone help me choose? Are there PF and VX radial datasheets known discoverable that I just haven't found? Should I just replace everything with FR? Here's what I have:
