Here's a newly racked pair of microphone preamps based on vintage Spectra Sonics 101 cards. These have been set up with a pair of Triad A-67J input transformers, which is the transformer that they'd have been used with originally in SS consoles. The output transformers would have originally been Triad HS-66's, or Spectra Sonics' own T-66 transformer which they began having made when Triad stopped making the HS-66. This set uses a 600:600 potted transformer from old Magna-Tech cinema preamps, which was actually magna tech's own replacement for the Triad HS-56 (the larger, better shielded version of the HS-66) which had been used in their earlier equipment. These are super high quality, humbucking core transformers, and after racking many many sets of spectra sonics card over the past 15 or so years, they're the ones I've found that make the best replacement for the the HS-66's which are hard to find and very expensive now.As these are intended for use as mic preamps, the input transformers are wired for 150 ohm input. This gives a total of 56dB gain maximum. There's a 3 position input pad with 0, -15 and -30dB attenuation. This pad is placed between the input transformer and amplifier card so that the mic will always be directly driving the transformer, and loads the transformer secondary with a constant 600 ohm resistive load in all three positions. That means that the transformer will always have the same source and load impedances in every position, and other than the reduced gain, will sound the same in any position. There are continuously variable output level controls using new-old-stock Allen Bradley 600 ohm bridged T attenuators, and there are also phase reverse and 48 volt phantom power controls on each channel.The Spectra Sonics cards have had their input and output electrolytic caps replaced to ensure they sound like they did when new, and everything's tested and working properly.
