I'm fixing an old mixer and need help identifying replacements for two potentiometers
I'm able to find similar but don't know what kind of taper they have
They both seem to be made by ALPS and are externaly the same (dimensions bellow)
one has XC502 on the pot and 5kzy on the schematic and measures 5kohm - function: preamp gain
the other has ac503 on the pot and 50KG on the schematic, has detent at 12 o'clock - function: aux send
shaft lenght 18mm, including collar 23mm
shaft diameter 6mm
total lenght (excluding terminals) 30mm
body 9,85mm x 11,85mm
Is very similar to image bellow:

Log/Lin makes not a lot of difference in your situation but your 50KG is probably Linear and likwise the 5k.
The originals were made by Bournes I think.

Was able to measure the 5k and it's Log as the halfway resistance is 4.5kOhm
The 50k is linear
On this mixer they are definitly ALPS,

Google-Fu identified them as ALPS RK09 series.
Just need to find the right ones:

(Always keep in mind, these could be special order parts, though.)

Ended up ordering a few pots from Ali express as alps apparently only has rk09 in 10k
For the 5k log I searched for a502, a5k, c502, c5k
For the 50k liner just searched for b503 or b50k with click
Also found another broken pot, this time a dual 50k for one of the stereo channels and this was w503 or w50k
