The fan in the 922 is a 120v fan. It runs off of half the primary when
the amp is configured for 220-240. There is a somewhat complicated
circuit that keeps it running for a while after the amp is shut off. But
in an emergency you can just connect to a source of 120v.

Hello all: I have a Kenwood TL-922 with a Harbach Soft-Start module
installed. Normally, I run my amp from 220vac, but I am currently on
a contest expedition in Labrador (Zone 2) and I have to run it off
110vac temporarily while at this location. I changed the taps through
the back panel to run the amp on 110v, and I have bypassed the
Harbach Soft-Start module. My problem is that the fan does not run at
all since I did this. I can't figure out why, and I dare not run the
amp without the fan. So, what can I do to get the fan running
again?1. Can I re-install the 220vac Harbach Soft-Start and run it
off 110vac?2. Is there some better configuration of the taps that
would get the fan running again? I am not in a position to test the
fan here and now, but I have every confidence that it works fine. I
used the amp on 220vac just a few days before I left for Labrador.
Jeff W8CQ at Harbach was unable to offer any advice, as he is not
familiar with the TL-922. 73, Dave VE9CB and VO2AAAplease work VO2AC
