Hi i have an crate v18-112 with three broken potentiometers(volume knobs), the level treble and reverb what pots should i buy to change them? Ive searched everywhere for anwsers but with no luck.

You must open up the amp, and see what is in it.
many different pots in the world, many different values , and many way to mount them.

impossible to say looking at the amp from the outside.

I have opened it and put everything back together except the three pots that are missing but i found the remains of two of them one of the pots was a b25k and the other was a 05a250k i think but im a beginner with this electronics i cant even read the schematic for the amp xD

Can you post a picture of them?

The treble is just snapped off on the end but the reverb and level is completely gone i will take it apart again tomorrow for a better picture.

We need a picture of one that isn't broken mounted on the circuit board.

If it's just a pot on the board with the three lugs mounted into the PCB, then it's a pretty standard part.

Yeah its those with the three pins that gpes into the board but i dont know wich ones not standard tubes in this amp either think they were russian

 

[corliss1]

Cool, so any standard pot with PCB pins will work. Just measure the size of the circle area of the pot - it'll be either 16mm or 24mm, and get the correct value, and you're good to go.

Just because they are Russian-made doesn't mean normal tubes won't work - it likely didn't come with those Russian tubes.

 

[Lucky1312acab]

Cool ill measure them then, but how do i find out what ohm they should be? I cant find the info anywhere and i cant read schematics, the tubes are aftermarket not original. I got it used and thank you for helping me i thought i was never gonna fix it

I'm taking data from this guy:

Looks like Treble would be 250K linear, and Reverb is 25K linear.

I don't for your location - they are common parts so find a place that's semi-local to avoid international shipping.
