May be, may be not. I see from pictures that your unit in fact uses a motorized dual Alps pot. Specifically this one.
It seems these are made I think in China now and some in Japan.
Anyhow it seems this device is causing trouble for a number of manufacturers, not just Parasound. It seems they have a high incidence of becoming noisy.
I note on some DIY sites people are modding units which have this device to take TKD units.
I would note I have had trouble with Alps pots once.
I had trouble with my Quad 44, I installed a unit from the Quad importer and it quickly failed. I got in touch with Quad, who said they had, had a lot of these fail. They sent me a control from a batch they knew were good and that control has not failed.
