A tale of 2 fuse holders.

[N3DRB The Derb]

Can you guess from looking at this picture which is the 3AG fuse holder you want in your kit bag for gear drawing 15 amps from the mains?

hint: one is scroteless and weak, the other one is not. Draw 15+ amps current through those little tiny solder tabs on the one on top? yah, right.

Sometimes future problems can be stopped before they happen just by observation.

Draw 15A ccs through either one, and the spring inside will get warm anyway.

The bottom one is nice, though.  The spring is generally the weakest link in any of those fuseholders.

the spring in the bottom one is strong enough to power a slop-bucket throwing trebuchet. 

The funny thing is that they both claim to be 15A@250 volt fuseholders. One is lying. I'd use the top one in a receiver or a light duty tx, but something that really draws 15A? Those solder terms are maybe half a mm thick.

top one made for greater glory of China, bottom one NOS Buss made in the US.

It has been installed into Jenny Gonset and is a wonder to behold with the new AC 3 wire and HD plug.

Miss Jenny is starting to look pretty sexy after her tummy tuck, boob job, etc.
