fuses - the $39 ones or the 85 cent ones

The best advice so far is to get the cheapo fuses first to make there are no problems with amp. Then if you insert the uber fuse let us know the results.
What kind of fuses does the amp use? Doesn't Radio Shack carry them?

I bought the uber fuse for my MC402 with the stock power cord and heard the difference.

The difference isn't as great as what I've heard between different brands of $400/1meter pair of interconnects, but then it was only 1/10 the cost and it is an improvement.

With only one fuse needed, I think it was worth it. I will purchase another one for my phono section in the future. Think of it as one monthly payment on a satellite TV or cell phone bill. This is from a cheapskate who doesn't have either.

Relax, have a homebrew and listen to some Lee Morgan...

the amp uses 4 slow blow fuses; 1 for each EL34, .250 mv and Rat Shack doesn't carry 'em.

Hey Joe- Any electronics store will have the correct Buss fuses you need. Sometimes a bad tube(internal, intermittent short perhaps) will blow a fuse. Hopefully it's not a transformer(worst case). DON'T buy Radioshlock fuses. They'll blow of their own accord and make you crazy(I've seen it too many times). AND as stated- DON'T try the high dollar ones until you're certain the amp's straight!!

Here's another log for the fire: (http://www.positive-feedback.com/Issue32/fuses.htm) These fuses are getting a lot of positive reactions for just being a "gimmick" it would seem! I'll be happy to wrap my little (Gold)fingers around some this weekend!
