onix OA20/2 input switch+volume pot

taka_a · 11th June 2004, 02:41 PM

Hi there.

I own a onix OA20/2 which i purchased some fourteen years ago. Now the input switch and the volume pot seems to be broken.

As for the input switch it seems to be very difficult to get an original spare part from ALPS.
I have also learnt from a local radio shack that ALPS stopped production of volume pots some years ago. I have seen ALPS pots in ebay, but I don't know which one could be used for the OA20/2 (ALPS RK27112, RK40312, etc.).

I really love this onix OA20/2 and I'd like to repair it.

Can you tell me if I can get any compatible parts for this amp (s/n 40476)?

Hi,

I have exactly the same problem. Did you ever get anywhere in sourcing these parts. I love this amp and would like to keep it.

Hi,

I finally got a cheapo rotary switch instead of the slider-switch. Soldering was not too difficult.
I've cleaned the volume pot with alcohol - it works fine.
