I have an old Crown D-75 amplifier that I acquired a while back and it works like a beaut except one of the volume pots is toast.
The pot has 2 different numbers stamped on it, both of which yield no results on Google.
Can I find out what value of pot to get by measuring with a multimeter?
Has anybody else had an experience doing a fix like this?
Is there a good place to buy parts like this? The pot doesn't look like the standard Radio Shack part (the post on the pot is pretty tiny) and I'd like to match the original as closely as possible.
Note: I do have proper electronic tools (like multimeter, wire strippers, soldering iron, etc) to be able to fix this issue.
Sidenote: This quesiton was spawned off of the question "Scratchy volume pot". Apparently, it's a common practice to clean out old pots when they start to make scratchy noises. Unfortunately, one of the two pots on my amp is completely toast so I need to replace it.
**Update: Sorry about the delay. Here's the pictures as promised.*
And the part numbers are 1378325, and D4688-4. I'm guessing that one is a part # and the other is a serial #.
After a close second look at the pictures provided I realized that the part number is actually D4688-4. After some googling I found out that Crown has a section on their site specifically for ordering replacement parts.
Here's the parts list. Turns out it's a 25K pot.
