Should L/R RCA center pins have the same resistance?

[saunaboi17]

My left center pin reads: 96.6k ohms and my right center pin reads: 105.2k ohms.
These are both within range, but I'm worried these differences will affect the L/R balance.
All my other resistance checks passed and I'm about to move to voltage checks.

Thank you,
Norman

These will not affect the balance.

If we assume you have a very, very weak source component with very high output impedance (say 10K as a worst possible scenario), then you will get a channel imbalance of 0.06dB.  If your source output impedance is lower than that (which is almost certainly is), then that difference will shrink.

We don't usually worry about a channel imbalance that's under 0.25dB.

Do note that the carbon track volume pots sometimes have mismatched channel balance at very low levels, and if you run into this it is addressed in the FAQ and an unrelated issue.
