I have finished the design for the Jensen Twin Servo 500, a variation of the original Jensen Twin Servo 990 Mic Preamp for the Lunchbox/500-series format. Here is the link to the pdf with preliminary information:

Hey,

Anyone ever compare the stock M5 with the one outfitted with Jensen Transformers? I used to have one of the latter, but it got completely destroyed. I recently got a standard one (without the Jensen transformers) and I can't help but feeling the like the jensen model sounded a bit brighter and bigger. Also, how much does it cost to get a standard m5 outfitted to include the jensens?

Don't hear much talk about the Jensen Twin Servo around here. Mercenary's description says it is the best mic preamp ever made, for what that is worth. Anyone use one? I am curious if anyone has done a comparison to the SCA J99 preamp, which is basically a clone for the most part.

Hey everyone,

This is a post for all the techies out there:
