Quick fuse question

@rodman99999 , I used a Slow-Blow 5A. I turned the amp on and it went in to its normal protection mode then shut down. looked at he fuse and it was blown.

Did you try it again, with the original fuse?    I just downloaded the manual.   Not really familiar, with your amp.                OK! I’m guessing that you mean the, "protect" LED lit, during the amp’s start-up, then the fuse blew.       Did the protection LED seem to be lit any longer than it normally would?      I ask, because a fuse wouldn't cause that.

@rodman99999 Yes, put the original fuse back and amp works fine

OK! Those fuses are made in China.     Even the high-Dollar, high-end (or whatever one deems them) fuses, from HI-FI and Synergistic (not certain about any others) will typically require a slightly higher rating, than stock.     Don’t ask me why!     That’s their recommendation.     It’s what I’ve encountered and have had no issues, with the (slightly) higher rated fuses.     You could try a 6A (a 20% increase).     I suppose: some would call it gambling.                     Then again: those from China are relatively cheap.    Try a few more of their 5A fuses, first.    Your original may have been a lemon.

@rodman99999  they are made in China but they are they same as AMR fuses from the UK. I really don't just want to place a higher value fuse in the amp. The original MDQ 5A fuse still works fine, the 5A standard fuse was a Bussman that I had from another component and it blew. I was going to get some HIFI Tuning but dont want to just through money down the drain if there not going to work.
