If you're really desperate, I assume the whole amps come up on Ebay for cheap if you wait for a broken one. There's lots of info about the A400 volume pots online that might give you ideas, e.g. pioneer a 400 volume pot

Hi, can anyone help please. I am trying to replace the volume pot on my Pioneer a400 amp.
I have purchased an alps pot. but am not sure how to wire it in.
I realise it cannot fit straight onto the pcb but would really appreciate some kind of
Wiring diagram.
I have scoured Google to no avail.
Hoping someone can help me.

Yes, they do come up on ebay, but tend to go for silly money even though faulty.
There is a lot online about the a400 vol. Pots, but no diagrams showing how to wire a replacement unfortunately.

Have you tried contacting Pioneer for schematics?

Fully working one on Ebay for 120 'buy now' atm...hardly silly money! use yours for spares.

I gave up on the A400 after having two that developed problems with the volume pot. It isn't such a great amp that it's worth all the hassle in my opinion, and can comfortably be bettered by current equivalents.

does this help any?


I have followed the wiring in the pics provided
and wired in the alps RK27 100K pot but have no sound, very faint on full volume.
Does this pot need to be grounded ?
Any help would be appreciated as I am a novice concerning amp circuitry.
Sorry the wiring is the same colour, it's all I had. 20201118_225416.jpg
