gallien-kruger 1001rb biamp issue

[OutsideUrbia]

I recently added a sansamp bass driver to my setup running it direct since it sound better than using the effects loop.

After 3 sessions playing like this....I was running bi amp mode playing through the 115rbh and another gk4x10. suddenly my volume dropped significantly leaving only the 4x10 running.

I thought the amp was screwed but diagnosed that it was the 115 rb speaker. I took off the back plate and was relieved to find that 2 fuses in it were blown. I found out also that the 2fuses where actualy automotive use light bulbs. However no radio shack or advanced autoparts store has them (12v15w)

where can I get these fuses?

I think those are called PXB fuses. Something like this...

Hey thanks Wes,
I looked into those. Eminence uses those "lamps" in their crossovers. could I assume these are the same one used in the 115rb's crossover?

another concern the lamps in the 115rb have pointed tips on the end of them. they don't look the same. as long as they are the same length they will fit alright though.

Wofers dont use the fuses. test the woofer to see if its blown. You can run run range into it and it wont damage it. If it's good, then we can test the crossover.

This is what im working with....

The horn is producing noise. the speaker/woofer is not.

I tried powering it through the 1/4'' on normal mode and got nothing

When hooked up in bi-amp mode with the speakon cable...the horn is sounding off plenty. the woofer has nothing.

In biamp mode, that switch should bypass the crossover completely, so you just have your amp plugged directly into the woofer. To be absolutely shure, you can remove the woofer and hook it up to some speaker wires of a home stereo and see if it works. If it does work, then check out the crossover or cab wiring, but it shouldn't.
