I’m playing around trying to covert an old theatre photo soundhead preamp to an MC RIAA. If you are not familiar, these usually have a high ratio transformer on the input on the order of 1:100 turns. This brings up the question of overloading the input tube on transients. I’ve searched but I can’t find a formula for calculating the maximum output of the cartridge given the output specification.
In this instance I would like to use a DL103R and the given specification is .25mV 1kHz @ 50mm /sec. horizontal. Is 500mm/sec. a safe value for maximum acceleration considering groove damage? Is the relationship between velocity and output voltage approximately linear? I.E if [email protected] 50mm/sec. then 2.5mV @ 500mm/sec.
Thanks
