I have been servicing Harman Kardon units for a while. With years I've developed deep respect toward Harman Kardon gear (especial tube gear). It is a pity to see how many units are
wasted/mutilated (drilled holes in the faceplate or chassis for a toggle switch installation, cord cutting for in-line switches etc), just because of the broken on/off switch! 
After many years of back and forth I decided to 
re-manufacture many of  Harman Kardon volume controls that were used back in the days. My main goal was to produce a high quality part that is better in comparison to the 
original volume pot.
I am glad to announce that I succeeded. I am very happy with the result and am sure you will be too!
This is modern production potentiometer. 
An exact copy of the original pot, but much better in terms of reliability and quality.

     
 Here are couple of points why one would be better off buying modern production pot for his/her Harman Kardon receiver:

1. Many original volume controls that Harman Kardon used came with huge design flows:
                     
 Unmatched potentiometer. 
             By now the majority of 60-year-old volume controls have deteriorated carbon resistance paths. Those must be matched and balanced because they play 
                a huge role in even sound distribution. 
                If a volume pot is unbalanced one speaker will sound louder than the other! 

All these issues have been addressed by this volume control. These are high quality factory made potentiometers. I use these controls when restoring customers' Harman Kardon units.
 Only positive results and well balanced sound. 
I see many posts on various forums where people are looking/asking for a good replacement.
I have a limited quantity. Will keep few for myself and help others with this hard to find pot. 
Please let me know if you have any questions. 
Thank you and let's make your Harman Kardon sing again!!!I also have many other pots available
