Well, there is a bit of difference between the two parts:
Palstar rotary L = 24 uHy, 139ドル.
Henry L = 28 uHy, 195,ドル
and Henry's smaller unit is 18 uHy and is priced at 155,ドル 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?
