Fuses amperage question

Hello--I'm planning on swapping out the fuses in my Unison Research Unico SE integrated amp, and I noticed something peculiar. While the booklet says that the six internal fuses should be 1A, 500mA, and 10A (two of each), I look at the circuit board ratings next to the fuses and got a different story: they were, respectively, 1.3A, 1A, and 1.6A. If I go ahead with changing the fuses, should I go by the manual or the circuit-board indications? Thanks in advance for any advice,

JB Coleman

Good Evening all. Both Steve McCormack & Kris Jeter of SMc Audio got back to me with my inquiry about the 10 amp fuses that were in the DNA-1 Deluxe I purchased.

Here is what Steve said via e-mail & Kris echoed in a seperate phone conversation.

"The DNA-1 was originally delivered with 8A Fast-Blow rail fuses. These were changed to 10A fairly quickly because we were seeing some "nuisance" blowing of the 8A fuses on turn-on. The 10A Fast-Blow has remained the standard DNA-1 rail fuse since then. You won't hurt anything by using a lower value so long as they are FAST Blow."

Well I'm relieved. Thank You again everyone for chiming in and Thanks to Steve McCormack and Kris Jeter.

Now onto the researching of "audiophile" fuses. ;) Don't worry I won't post anything on this thread I'll read the older ones on the forum

All the best.

FWIW, Steve McCormack installs Furutech fuses in his VRE-1 preamp.
