Help "defuse" my fuse dilemma!

raindog.promo

sorry for the terrible pun.

I have an amplifier which blew an internal fuse the other day.
The fuse is a T1.6AL 250v
(amp = alesis RA150)

I tried another 1.6a fuse which blew immediately and got onto customer support who told me it must be a "slow blow" fuse.

I've been checking peats and maplin and found these "time delay" fuses, glass, 1.6A

Would these be the same thing?

BTW, wasn't too sure if this was the right place, mods, feel free to movee thread, although because it's an amplifier, though these good people may know the answer.

Cheers.

Probably .... but I've never heard the term 'time delay' referring to a fuse before.

The idea of a Slo-Blow is that on start up there might be a short peak of over 1.6 amps as the amp powers up. This isn't a problem.

However sustained current draw of over 1.6 amps will make the fuse blow, protecting the Amplifier.

T would stand for time delay,Pauls right about the peak issue.
F before the Amp rating eg F1.6A stands for "Fast acting".This type would blow straight away.

Now,assuming that there isn't a fault in the amp(usually the power supply stage),then replacing with a time delay fuse should sort you out.

Anyone know what the "L" stands for?

T1.6AL


"L"ook it up says you. Jaysus, I'm on fire with these grammatical jokes today.

'L' as in Ampere ...obviously

I've finally got some fueses for this and they're blowing instantly.

The fuses are T2AL, 250V. I can't see anything wrong inside the amp. Has anyone got any advice? Would it be worth leaving it in with someone to repair?

Does anyone know people that do repairs?

Thanks.

?? A= Amps, "L" is inductance. I don't know what L means for a fuse...

If you can get to Fermoy in Cork, Baylors have an excellent repair dude.

Thanks, but I may try closer to home first. It's a pain in the hole, I'm ready to start doing some recording, but have to use headphones for the moment (which I recently broke as well).

Where are you raindog?

COOKSTER

Are you powering it up while connected to speakers, or speaker cable, connected to output? If either of these are shorting out they can cause this fuse to blow.
If it is definitely fried you could try Mark in Session Hire, he's good with his amps. A bit more costly but on-the-ball too is Mick in Sound Communications.
Don't know who the official service centre is in Ireland

Tallaght, Dublin. Most places southside are no problem to get to.

No. Powering it up while not connected to anything.
