The little penny sized MOVs are too small, the sub should be more like
the size of a quarter. Radio Smack used to sell the GE or whatever MOVs
that were the 'right' size, and the number was the same or similar to
yours, above.
However that being said, if you listen to "w_tom", you will _never_ever
trust a surge suppressor power strip to protect your equipment. I agree
with him on many points, but the guy's an opinionated hardcore fanatic,
IMHO. I say just cut out the MOVs and use the power strip without them.
If the power supplies in the equipment _really_ needed the MOVs, they
would have put them in the power supply. If you really want to protect
your equipment, use an isolation transformer between it and the AC line.
