20K trimmer (Lowww)

I have completed the SMR4 board apart from one part - the 20K trimmer. There are four trimmers in the kit, but they are all identically marked:
H502I and P1009 on the top and
3296 on the side.

I have assumed that they are all 5K - is this correct ( I have inserted them as if they are)

Should there have been three of one type and one different per the instructions and parts list?
Can I just install the one that is remaining?


that’s correct, they’re 5K.

if you put the 5K in the place of the 20K you’d lose 3/4 of the pot’s range, so unless the spot you need is in the 1st quarter of the 20K you’d not be able to tune that correctly…
