Multia SCSI term power fuse?

I've been thinking about ways to reduce the power usage of
the Multia, to ease the strain on the wimpy power connector.
I've removed the floppy drive, and the internal SCSI drive.
No PCI card. Perhaps I can disconnect the fuse for the SCSI
term power, and have the external disk box supply term power
instead. But... I can't find the SCSI term power fuse.
They usually have the type that looks like a small resistor.
Where did they hide the fuse? It does have a fuse, right?

Is it possible to UNDERclock a Multia? (yeah I know,
it is slow enough already.)

I just reached into the miscellaneous pile of stuff at the back of my
computer table, and picked up a Multia SCSI controller. At one end it
has a flat-pack resistor array labeled 221/331 which is the SCSI
terminator. Nothing nearby looks like a fuse to me.

Kirchoff's law being what it is, or maybe it's Thevenin, you could
just supply term power from both ends of the bus, and that way the
Multia would have to provide only half, for its end of the bus.
