Nikko Stereo NR550 Volume control resistor part number
I have a Nikko Stereo NR-550. The volume resistor is broken. I need the part number and where to purchase it. I found an other unit NR320 that had a volume control of 250K pot with part number 4321330 but I can not find the part any where.
Service manual or parts list, part number for volume control would be great and where it can be purchased.
Thanks in advance
