Fuse help for a Marshall SLP 100 reissue

I just blew my mains fuse. It says it is a T4A fuse. Smaller than most fuses I have seen. Are these hard to come buy? Anything else I could use?

Is it smaller than 1 1/4" x 1/4"? That is the most common size for amp fuses. In T4A THE "T"=Time Delay commonly referred to as Slow Blow and sometimes labeled with an "S" instead of a "T". The 4A means 4 amps and it probably says either 120v or 250v on there as well. If the fuse is 1 1/4" x 1/4" you can get a 4 pack at Radio Shack or most auto parts stores for under $5 (If you don't have any funds my money order should be there soon

).
Just make sure you get a Time Delay/Slow Blow fuse that is 4 amps. The 120v or 250v rating doesn't matter that much here in the US so either will work fine.

I don't recommend using any other type of fuse than what is meant to go in your amp, if you do, you risk major damage to your amp
I hope this helps.

Thanks man. Went out and bought new fuses. I did the tube test only to find that I have a bad 6550 tube. Oh well. I pulled the two inner tubes, halved my ohmage and I am rocking again. I am taking it in for a retube asap. I am thinking KT88's this time around.

That sucks.
I just put JJ KT88'S In my Sunn Sorado they sound awesome, but they are really wide so make sure you have enough room for them before you buy them. I got mine from Eurotubes (
http://www.eurotubes.com/). They have the best prices I could find and awesome customer service too.
I got the IC Muff just in time for practice tonight, thanks again.

It sounds like it's supposed to which is good but I'm just not sure it's my thing. I also just got a Skullytone Russian Spy and a Pharaoh so I may put it back up on the B/S/T.
