Fotog Posted March 10, 2014 Share Posted March 10, 2014 Where do I find a replacement fuse for my KSW 150? Been to Radio Shack and a local automotive store. The fuse that came out says 3.15A 250V. I interpret that as 3 amps and 250 volts. Quote Link to comment Share on other sites More sharing options...
001 Posted March 10, 2014 Share Posted March 10, 2014 never seen a 3.15 fuse. im sure 3a would be close enough or maybe 3.5. check parts express, or i found a good selection of fast blow fuses at home stores like home depot or lowes etc. are you reading the actual fuse rating or what thee amp board says? cant imagine klipsch would use such an odd rated fuse. 1 Quote Link to comment Share on other sites More sharing options...
Fotog Posted March 10, 2014 Author Share Posted March 10, 2014 Very possible I am mis-reading it. The fuse says "T3.15L" then 250V. Quote Link to comment Share on other sites More sharing options...
001 Posted March 10, 2014 Share Posted March 10, 2014 sounds like you are reading it right... i just checked my parts express catalog & no 3.15 listed anywhere. just whole numbers past 2.5 & even the lower values are in .25 increments. what does the amp board say where the fuse goes in? usually the rating is listed there. im sure a 3a would be fine. 1 Quote Link to comment Share on other sites More sharing options...
Fotog Posted March 10, 2014 Author Share Posted March 10, 2014 The amp board says 3A 250V. I will check Home Depot. Thank you for the feedback. Quote Link to comment Share on other sites More sharing options...

Fotog Posted March 10, 2014 Author Share Posted March 10, 2014 Ok...picked up a 2pk of Bussman 3 amp fuses at Home Depot. Package says for electronics etc. and for applications of 3 amps and 250V. Put one in my sub and I get power for about 5 seconds and the new fuse blows. Any ideas? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted March 10, 2014 Share Posted March 10, 2014 Sounds like a bad amp. Have you had it out yet? You may be able to see a bad spot on the board. 1 Quote Link to comment Share on other sites More sharing options...
Fotog Posted March 10, 2014 Author Share Posted March 10, 2014 (edited) Thank you CECAA850. Wouldn't have a clue what to even look for. Not even sure where to take it. The only place around here selling Klipsch products anymore is Best Buy. All the higher end "audio" stores have gone out of business. Any thoughts on who to call? Would a guitar amplifier service be able to look at it? Or is it simply better to buy another? Edited March 10, 2014 by Fotog Quote Link to comment Share on other sites More sharing options...
001 Posted March 10, 2014 Share Posted March 10, 2014 (edited) should say "fast blow" on the package, or did you compare to the other type that has a very thick bar vs a super thin wire. the thicker bar is usually for auto use or the slow blow type from what i have seen. i agree, if its blowing right away there is either a> something wrong with the amp or b> something as simple as speaker wires touching. were you pushing them hard to blow the first fuse? if you take it out try & look for any obvious burned or brown spots on the circuit paths or bulging/leaking capacitors etc. as for who to take it to, check your local yellow pages for audio/electronics repair places. theres usualy a couple places that can repair or check something like that out. or call best buy & see if they can refer you to someone. or last option is to call klipsch to see if they even sell a replacement or can suggest a repair place they might use for warranty work etc. on a side note, i had a sub amp on a set of my def tech speakers go out from constant high volume levels & probably age (5+years). one thing i will say about def tech, besides pretty darn good sound, is that they have the best customer service in the business, sent me free replacement amps with no questions asked, & no proof of purchase, (i bought them used) just inquired where i can get new ones or have mine repaired & they proactively offered to send me new amps. even sent a replacement woofer "just in case." now thats what i call taking care of your customers.

Fotog Posted March 11, 2014 Author Share Posted March 11, 2014 Thanks klipschfancf4. The original fuse I believe has a thicker wire then the replacements I bought but it is merely my perception and could be totally wrong. I will check the yellow pages. No speaker wires touching and no excessive volume (I get enough bass from the KLF30's - just use the KSW150 for "color"). I recall the sub had a burnt smell when the fuse blew - so I suspected it was bigger than just a fuse but thought I would start there. Thanks again for the guidance.

CECAA850 Posted March 11, 2014 Share Posted March 11, 2014 The KSW-150 has been around a while. I wouldn't invest a ton of money in it if the amp is fried. It's tough to find people to work on them as Klipsch doesn't like to give out the schematics on their sub amps. 1 Quote Link to comment Share on other sites More sharing options...

If you've already let the magic smoke out of the amp and your fuses blow in 5 seconds, it's time to take it apart and look around inside or punt it. 1 Quote Link to comment Share on other sites More sharing options...

He said that the one that came out of it was a 3.15A fuse. yes, but i asked him to check the actual rating on the amp itself & he said it was indeed 3A. so someone used a 3.15 in there, but for what reason? if the amp say 3a fuse... you should be using a 3a fuse IMO.

Fotog Posted March 12, 2014 Author Share Posted March 12, 2014 I am the original owner of this sub and the fuse removed is the original fuse. The markings on the fuse clearly state "T3.15L" "250V". Unless the high end store I purchased this KSW-150 from placed a different fuse in it, this fuse came from Klipsch. Thank you all for the council and advice. It is the reason I asked and am happy to get your feedback. Again - Thanks. Quote Link to comment Share on other sites More sharing options...
