I am helping a friend to repair her amplifier. A different friend took a look at it, and they were able to identify the circled part as being the one to blame. However, apparently this is a part that was made specifically for this amplifier and is no longer made, so my task is to figure out what to do. I have some electronics expertise, but mostly I was recruited because I am good at finding things.

However, it would be a good start if I knew what this component was. I’ve not been able to find it in any of my reference materials, so I was wondering if y’all might be able to help. The person who identified this part is not able to help clarify, as she’s off the grid for the next 3-4 months.

(On the off chance that someone here has some specific expertise on this particular amp, it’s the Kenwood KA-3020SE)

Edit: Now that I know it’s a potentiometer, the biggest challenge is understanding what 200KBH what is necessary to replace the part. It’s a 200kΩ one, that’s straightforward enough. It also seems that the “B” means linear response (found by checking my electronics reference book section on potentiometers, and cross referencing with other balance control pots for other amps, which specifies linear). I’m puzzling about what the H could mean though.

The big challenge, I’m told, is finding a part that will physically fit. There are 6 contacts on the part, which means it’s a dual ganged potentiometer. However, most that I can find online have the pins in a 2*3 arrangement, like this, whereas this one is 1x6, like this.
