loser7787 Posted April 28, 2014 Share Posted April 28, 2014 Hi guys, My DT25 stopped outputting sound recently. I thought it was something different because it happened immediately after updating the firmware to 2.00. After downgrading and checking wires/connections I tried the direct out into my toneport and it worked fine. Upon further inspection I found the tube protection fuse is fried. I understand this usually happens when a tube goes bad but I took the back panel off and there is no sign of tube being blown out or damaged. No discoloration or anything like that. I figured I would order a few fuses and if it blows again I will replace the tubes. Problem is I cant find the exact fuse I need. There were 2 forum posts here with the right fuses but going back they are all crossed out and saying they are in fact not the correct fuse. To my understanding I need a .375 Amp / 375 Milliamp 250v Slo Blo fuse. Can someone please send me a link or two where I could purchase these just so I don't need to wonder if i'm in fact buying the correct fuse. Any help/comment is appreciated. Thanks.

loser7787 Posted May 5, 2014 Author Share Posted May 5, 2014 Anyone, please! I am really hurting not having my DT up and running. Obviously people here have ordered replacement fuses. Just need a link to the correct tube protection fuse. Please and thank you! Quote Link to comment Share on other sites More sharing options...
TheRealZap Posted May 5, 2014 Share Posted May 5, 2014 i recommend calling: http://line6.com/company/contact/ any info you get on here may not be as accurate as you'd like... meaning that the fuses can vary by your region of the world and what you are feeding into your amp.

loser7787 Posted February 15, 2015 Author Share Posted February 15, 2015 I know this is awhile later but just trying once more. Just playing with the HD500 direct to some monitors has sounded great and delayed me attempting to replace the fuse. Finally think I'm going to call Line 6. I am located in the US if that helps find the correct fuse. I am reading about people replacing the tube protection fuse. Does anyone have a link for DT25 replacement fuse. I just got my JTV and I am itching to get the dream rig up and running. Would this work? http://www.amazon.com/Cartridge-Fuses-250V-375A-Slo-Blo/dp/B00LQPQ1EC I am finding .375 Amp 250v slow blow fuses but some of the picture show a smaller looking fuse than I need. Any help is appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
DarrellM5 Posted February 15, 2015 Share Posted February 15, 2015 Okay. Here's what I bought. Bussmann MDL-3/8 I got them through ebay. Here's a link to a similar deal: http://www.ebay.com/itm/LOT-5-EA-MDL-3-8-MDL3-8-BUSS-BUSSMANN-FUSES-250V-/400860455131?pt=LH_DefaultDomain_0&hash=item5d552520db I bought the other fuse from Radio Shack P/N 270-1064 Quote Link to comment Share on other sites More sharing options...
innovine Posted February 16, 2015 Share Posted February 16, 2015 Anyone know if a 400mA fuse is close enough? Screw line6 for using such an obscure value on a wear-n-tear component. Quote Link to comment Share on other sites More sharing options...
innovine Posted March 4, 2015 Share Posted March 4, 2015 I still didn't find an easy source for the fuse, so I put in a 315mA fast one instead. Seems to work ok so far :) Quote Link to comment Share on other sites More sharing options...
geppert Posted March 4, 2015 Share Posted March 4, 2015 Having gone through all this ..... and From My thread below .... http://line6.com/support/topic/10327-dt25-head-dead/ The tube protection fuse is the tough one to find ... the line fuse is pretty much available at any guitar shop. The actual Tube Protection fuse I have in my DT25 (375mA/250V Slo Blo) is a LittelFuse 0313.375 Mouser Part # 576-0313.375MXP Manufacturer: LittelFuse Manufacturer Part Number: 0313.375MXP http://ca.mouser.com...4H0c833ETykqA== The Bussmann MDL 3/8 is an equivalent. Mouser Part Number: 504-MDL-3/8 Manufacturer: Eaton Manufacturer Part Number: BK/MDL-3/8 http://ca.mouser.com...Tq0cGO5NIGsxA== 2 Quote Link to comment Share on other sites More sharing options...
loser7787 Posted May 19, 2015 Author Share Posted May 19, 2015 Thanks guys! I did call line 6 about a month ago and they gave me a part number and a site to get it from but the part number didn't come up at all ha. I just ordered from the mouser links posted above. Hoping it was indeed just a blown fuse and not the tubes failing but I ordered a few extra just incase. Thanks again for the input! Quote Link to comment Share on other sites More sharing options...
bbqchickenrobot Posted February 1, 2021 Share Posted February 1, 2021 @loser7787 - any feedback on the fuse(s) you got ? My DT50 recently got SUPER quiet and barely has any output volume at all. Thinking it's either the tubes or the fuse. Ordering replacements for both now.... curious your experience on these. Quote Link to comment Share on other sites More sharing options...
