Roland Jazz Chorus

[helmer567]

Hi All!
I just got an old Roland Jazz Chorus from 1983. The fuse is missing. It needs a 5 A / 125 Volt fuse. The problem is the fuses I bought are too small and there is apparently no bigger fuses (they are all 250V) at Radio Shack.
Does anybody know what to do?

You bought 5x20mm metric fuses.....you need the regular "3AG" size (1-1/4x1/4"). That'd be a Buss AGC5 or MDL5 if it wants a slo-blo.

Thank you

Thanks so much...where would I get such a specific fuse?

It's not specific, it is generic. A plain old 5A fuse should be a stock item at Radio Shack, most hardware stores, even maybe a hobby shop.

Fuses you are likely to run into come in two sizes - the small 5x20mm size, and the "American" size 1/4" by1-1/4". They also, in both sizes, come in regular blow (also called fast blow) and slow blow (also called time delay). And then there is the current.

Ignore the 125v/250v thing. ANy voltage rating they sell will be fine.

Radio Shack stock numbers:

270-1011 5A fast 1-1/4"

270-1056 5A fast 20mm

270-1067 5A slow 20mm
