DIYRE CTX MkII (PAIR) preamp transformer discrete opamp module 2019

A pair of DIYRE preamp character color modules, used in some of my Mister Focus 500-series modules (see other listings!). These sound amazing, and I had fun trying various discrete opamps in these, but always preferred the opamps they were designed around, the RED-25 (Included with each). I ended up getting a separate pair of modules for testing other discrete opamps specifically, also for sale in another listing! These are hard to find, and if you are reading this you probably are among the special group of people who really appreciate these color modules. Thanks for looking!
