What Size And Type Fuses For Nashvile 400?

Steve Alonzo Walker · From: Spartanburg,S.C. USA (deceased)

My amp blew the fuse located under the transformer and I need to get the correct replacement fuse. Also, What color speaker wire goes to the + speaker connection? Thanks!

The yellow wire is positive (red terminal) blue wire is negative (black terminal). I would be very careful to check for dc voltage on the speaker output before connecting both speaker wires. DC can burn up the speaker in about 1 second!

If you blew a fuse there is likely a problem with the amp. If you have a meter and can check that but, be very careful not to short the speaker wires, you can blow the output transistors is less than a second with a short on those wires.

The primary fuse is listed as a 6 amp fuse. However the fuse type is not listed on the schematic. I know it is not a 312 (clear glass, fast- blo) or 313 (clear glass, slo-blo) series. I have never had to replace one and have not taken one out to determine the type fuse.
