Hi All,

Just finished with the mods for a TL-922 and thought I would pass along a
tip.

Raychem now has 250 volt poly fuses in several usable values.  These are
self resetting thermal fuses that are common in computers these days.  I
installed one in the 110 volt DC supply to protect the filament transformer.
Should work in the SB-220 as well.

These are available in DigiKey.

Anybody see a problem with this type of protection circuit?
