I need to replace four n38 ic protector fuses, they look like a TO92 transistor just with the middle pin missing. To my knowledge they are a 50v 1.5 amp normal blow fuse. Anyone know where i can get them or another kind of fuse to do the job? I was thinking maybe Pico fuses would work

Thanks a ton skippy, Before i order them tho, i have a box of pico fuses rated at 250v 1.5 amp. Could i use these or would i smarter to order the IPCN38? it's for the driver circuit in a amplifier i'm repairing. Someone shorted out the headphone jack and blew the fuses.

It depends on the specs of the pico fuses you have, are they slow blow, fast blow or very fast blow?

The fast blow should be OK, do you have a part number for the ones you have?

There the ones VintageA, quick and fast blow they are the same thing, the reason I used the quick blows 1st is to protect the circuit, because with the same rated fuse if it was to go again it means there is a fault condition. If you encounter it doesnt blow and everything works then all is well! :P

Somewhere on that fues should have a letter "F" for fast or "S" for slow!

The original n68 fuses in the amplifier are 2x n38e, n38 b and n38 m, are they all different or just different batch numbers?

Thought of a possible problem with using the pico fuses. The n38 fuses are rated for 1.5 amps continuous and the pico fuses blow out current is 1.5 amps.

Bump, I've been reluctant to put in the pico fuses because they blow at 1.5 amps and the ic fuses are rated for 1.5 amps continuous. would i be better off going with 2amp pico fuses or just using the 1.5 amp ones?
