PGM Resistor Pack Replacements

Hello:

I'm trying to revive a dead PGM board and several of the resistor packs are completely broken off. The smaller one with 8 pins labeled "RSA1" and the larger 10 pin one labeled "RSEC3". Would anyone know where to get these or the values/specifications to aid in my search?

I have a parts board somewhere. I'll see if I can find it and desolder them for you.

I'm gonna check my storage if I have any PGM boards. I remember still having one. If you give me the ohms reading from the VCC pin I can check if the neo ones will work.

Basically there should be two values:

Pin 1 - VCC
Pin 2 - Resistance 1
Pin 3 - Resistance 2

So I would need the value from Pin 1 to Pin 2, Pin 1 to Pin 3 and then from Pin 2 to pin 3(should be the combined value of 2 and 3).

I am getting some odd readings. :scratch:

On the ones labeled RSA1 (removed from the board), I am getting:
10.42 from pin 1 to pin 2
5.24 from pin 1 to pin 3
8.78 from pin 2 to pin 3.

On the ones labeled RSEC3 (removed from the board), I am getting:
10.4 from pin 1 to pin 2
10.0 from pin 1 to pin 3
(not kidding here) 328.0 from pin 2 to pin 3.

I have a good multi-meter with good batteries and the values are steady. I even sanded down the metal a bit to promote good contact.

Checking a different RSA1 that was still soldered to the board, I get:
8.76 from pin 1 to pin 2
7.90 from pin 1 to pin 3
2.63 from pin 2 to pin 3.

I also tried starting from the opposite side but the values on pin 1/2/3 combinations in that direction were all open. (All these are in kOhms, by the way.)

I've got another dead PGM board coming that I may be able to salvage parts from as well... if I can clear off the rust.

Wow, that's really strange. Do the controller inputs still work as they should?
