Hello!
I use a transducer and preamp (from Schertler Corp.) for my double
bass. When I upgraded, the new preamp had only balanced out, but my
amp has only unbalanced in. A Radio Shack adapter works, but I don't
like the way it sticks out of the amp. I tried a cable connecting pin
2 of the XLR to the tip of the 1/4" jack. It sort of worked, but there
was huge attenuation which made S/N an issue . What I'd like to do is
mount a matching transformer inside the amp (Hartke) itself with a TRS
jack. Can anyone recommend a simple circuit using a transformer
commonly available from Mouser or the like? FR should be at least 30
to 10k Hz, and I'm hoping not to spend a princess's dowry.
Thanks,
Rob

Please *CROSSPOST* such questions that are relevant to muliple groups. It
is better netiquette than multi-posting where you are also likely to get
conflicting responses that the other groups can't see, so you can end up
more confused than you started.
