    Smithline 2 x 4 speaker fuse

    I just blew my two 2 x 4 smithline speaker fuses and need to replace them but don't know where to find them. The smithline contact phone number is a wrong number at this point. It looks like a fast blow thin wire fuse about 1 1/4 inches long.

    Where do you buy fuses from and is this right for Revox B77?

    B77 fuse blew while fast forwarding It is a 5x20 1500ma 250v slow burn. Is that the right fuse for the USA? And where do you buy them? I tried car shops and Lowes and they didn't have any. Thanks

    Sansui AU 7900 Recap

    I am in the process of recapping a Sansui AU 7900. It works fine, but it was pretty beat up. Not sure if the sound is as expected plus there is also a cold solder somewhere in the main board. So thought I'd replace the usual prone to fail components (Caps, VD1212, fuse resistors) with new ones...

    Hello - I just acquired a ($20) 331 that was known to blow a fuse. Upon inspection, F604 was blown. I replaced and it failed dim bulb test. I then replaced C603 and C609 on questionable visual inspection - it seemed to pass DBT (albeit the bulb flickered in a strange way) So, I brought it up...

    Quick question on Advent Heritage fuse

    What is the correct size please? I bought a pair from an auction. The crossover needed some heat to reattach things. One speaker has a fuse marked 250V/7A, the other has a bent box staple. The one reference place I found was confusing and suggested a much larger fuse than 7A. The specs...
