In Reply to: Strapping Stereo Cartridge for Mono-Effect on Output? posted by blake on December 24, 2016 at 12:30:37:
Here are my thoughts:
There are two ways to strap the two channels together. If you connect the two positive pins together and connect the two negative pins together you would halve the impedance from 14-ohms to 7-ohms and double the current. Cartridge output voltage would remain the same.
On the other hand, if you connect a positive pin to a negative pin of the opposite channel and take cartridge output from the remaining two pins, you would double cartridge impedance from 14-ohms to 28-ohms and you would also double voltage output from 0.3-mV to 0.6-mV, but current output would remain the same into a current mode phono stage.
The first option would double sound level with a current mode phono stage and the second option would double sound level with a standard voltage mode phono stage.
Anyway, I'm pretty sure this is correct, but I could be wrong.
Merry Christmas!
