[Amps] Replacing a Henry roller inductor...

[Philip Leonard WVØT]

Has anyone replaced the roller inductor in a Henry amp?  In my 3K 
Classic X MkII the coil forms have degraded to the point that the coil 
is no longer concentric with the roller.  The forms have actually 
started to break up.  This is causing the roller contactor to become 
intermittent (ie, doesn't always remain in contact with the coil).

I've look at the roller inductors that Surplus Sales of Nebraska sells 
and I'm wondering if their model (IRV) RI-40 would work as a replacement.

Has anyone tried this?  Any suggestions?

Thanks, Philip
