Well,  there is a bit of difference between the two parts:

Palstar rotary L = 24 uHy, $139.

Henry L = 28 uHy, $195,

and Henry's smaller unit is 18 uHy and is priced at $155,  so
yes,  the prices are higher for the Henry units.

I can't find the length/diameter numbers for the Henry unit,  but
looks big in the amp photos.  

BTW,  I don't see a smaller/larger one at the Palstar site;  have
I overlooked it?
