Subject: Tuner inductor
I also have a Henry 2 K Classic, it is the X version.
Some time ago, I asked the same question, the roller gets sticky in the sweet
spots, or squeaks.
I got a little dab will do you from Palstar as I had purchased an AT4K from
them and they use a lube on their roller inductor too. That worked about a
year, then as it collected dust got worse again. This stuff is black.
I also requested some when I ordered what I was told was the last roller
inductor from Henry for the 2 K Classic, although you might give them a call
and see if they have found any more. They sent a small packet of the grease
they use. This stuff is more grease like looking.
Best of luck, that is the only draw back I see to the Henry 2K design. I have
often thought about changing the plate caps to a vacuum variable after logging
the postion of the roller inductor for all bands at both high and low plate
voltages for SSB and CW settings. That would probably make this an awesome and
more easily tuned amplifier, even if one had to go to soldered connections to
the roller to a band switch instead of the switched plate tune caps.
Just rambling thoughts. A great amp otherwise.
