Bassdriver Posted August 3, 2015 Posted August 3, 2015 Hi all, My V6 blew its main fuse the other night, the one in the little sliding holder just below the mains input socket. The blown fuse is a T3.15AL250v. The closest I can find round here today are F3.15AL250V. I've bought 5 of them. Will they be ok to put in the amp? I'll see about getting some T3.15 ones when I can but will the Fs be ok in the mean time, even just to test the amp for now? Quote
ahpook Posted August 3, 2015 Posted August 3, 2015 (edited) It depends on whether the inrush current will fry the fast blow fuse. It may just blow as soon as you turn it on. I'd say give it a whirl, but I'm no valve amp expert...see what others say. Edited August 3, 2015 by ahpook Quote
Bassdriver Posted August 3, 2015 Author Posted August 3, 2015 So does the F indicate a faster blowing fuse? In which case the F is safer from the amps point of view because it'd blow faster? Quote
Bassdriver Posted August 3, 2015 Author Posted August 3, 2015 My Guitarist thinks the fuse blew because I hadn't plugged in the mains cable fully. The amp ran on standby without any problem. When I flicked the switch to start playing the amp cut out. I just want to run the amp in the house today and find out whether it was the mains cable or if there's something else going on. I can get a T fuse later if all's well, just don't want to risk frying anything else by using an unsuitable fuse to test the amp. Quote
Bassdriver Posted August 4, 2015 Author Posted August 4, 2015 The F fuse seems to work ok in the amp at sensible house volume so now I'm wondering if it'll be ok in a gig situation. Will gigging volume put more of a strain on the fuse? I'm going to get some T fuses asap and put one in, just curious how the Fs would cope. Quote
planer Posted August 4, 2015 Posted August 4, 2015 The fuse is still the right current rating, it's just that 'F' type foozes will blow faster once the current rating has been reached (or exceeded). A 'T' rated fuse will handle current fluctutations close to (or just beyond) the rating better than an 'F' type, that's all. If you ran your amp full bore, all the time, it might be an issue. I've got some T type, 3.15A 20mm fuses here, pm me your address and I'll send you a couple. Quote

[/quote] Thanks, that's a generous offer sir but as I have ordered some on Ebay for not very much money if feel it would only be greedy to make you send more. They'll be here on Thursday in time for my next gigs so all is well. Thanks Quote
