    Google isn't much help so I'm asking the experts @agedhorse

    I scored a 400rb cheap with a blown fuse. The panel states T5A 250V. Nobody seems to have these available. Parts houses and Radio Shacks are history in my city of millions, so I'm left with hardware stores. Neither Lowes or Home Depot had anything, and Ace Hardware (which has a fairly good selection of fuses) had only MDL 5A which is the closest I can find.

    It seems there may be a nomenclature issue here as slo blo, slow blow and time delay all come into play.

    So my question is: is there another name for T5A? or a proper substitution?

    Thanks in advance.

    Yeah, I'll do that if necessary, just curious why I can't find such a common item locally

    Ahhh...nobody makes any money any more keeping every fuse in stock?

    You might find 'em at a good auto parts store. What do you have against Amazon?

    What I haven't been able to find is a good local source for those hook-thingys that one uses to fasten up the hook fasteners on shoes...used to be able to find those in every dry-goods store and mercantile.

    T is a slow blow or time delay fuse.

    If the fuse blows again, stop. It's tech time.

    I wouldn't be surprised if Ace has something that will work. Luckily I have one about two blocks from my house and they have a kit with bulk fuses in bins. A couple of times I have gone down there with a small ruler and scratch pad, so I could find fuses of the right size and write down their codes and then drive home and use the internet to figure out which ones are fast blow and which ones are slow blow.

    Electronics supply store. If your in a decent sized city you’ll have one nearby. Probably not open till Monday.

    Wrap the old fuse in your cigarette package or chewing gum foil:woot:

    No,don’t do that

  9. Yeas ago I used to buy Piher controls with a 3" long x 1/4" shaft that you would cut to the desired length. A friend saw some of the shaft cut-offs and asked what they were for. I replied, "Those are perpetual replacement fuses. Install one of these, and blown fuses are a thing of the past!":D

    This ^

    Gotta separate the power supply from the rest of the guts to determine if it’s a power supply or amplifier issue.

    When you find them, buy three or four and duct tape one to the back of the unit. Then you won't have to go through the process again.

    I always buy a pack of 5 fuses whenever I get anything that has a fuse. The local electronics shops in my area are pretty much worthless it comes to things like this. Even trying to get a fuse for a Fluke meter that they sell is almost impossible. They do, however, carry everything else from lawn chairs with built-in speakers, to cup holders that vibrate to continually mix your drink, to LED flashlights that double as a an emergency glass breaker.

    Don't use duct tape, the adhesive transfers to everything it touches and degrades, leaving a huge mess that can destroy electrical contact surfaces (and make a mess of the amp chassis as well)

    Have you looked at auto parts stores? Odds are you'll find it there.

    I used to keep a stash of spare fuses in a magnetic Hide-a-Key thing. Stuck it to the steel chassis of my amp.
  18. Stop. Tech time.

    And if the circuit’s live, you can’t touch this.

    Fuses blow for a reason and the reason usually is not innocuous. I'm with the tech time crowd.
  20. The $20 local price tag was a good motivator for me to avoid popping the Fluke fuses.
