Ampex 350 Mod

Ampex 350 Mic Pre Optimizaton Mod: This mod turns a somewhat unusable Ampex 350 electronics channel into one of the most impressive mic pres ever!  Capitalizing on a fantastic design by the brilliant Ampex engineers this mod eliminates drawbacks to practical use in the recording of music while preserving and even teasing out a bit more of the inherent impressive sound.  The result is totally usable hot neon like sound that is unmatched by  other mic pres, a close second perhaps being the Neumann V76.  This modified mic pre has all-around utility:  it is thunderously punchy, has a w..

Ampex AM10 Mod

Ampex AM-10 Mic Pre Mixer Mod: The Ampex AM-10  is a fine little mixer from the early/mid transistor era.  The circuitry is very basic Class A resulting in an overall smooth, clean sound.  The microphone input transformer is interesting in that it is very small...sometimes referred to as a “thumb” transformer.  Usually a small transformer lacks low end response, as theory says it will saturate easily and thus attenuate peaks of low frequency signal.   Somehow the  thumb transformer in the AM-10 is able to pass low frequencies with minimal saturation. The saturation or loss of low freq..

Ampex MX35 Mod

Ampex MX-35 Mic Pre Mixer Mod: The Ampex MX-35  is a fine little mixer from the late tube era.  The circuitry is straight forward Class A (as are most tube circuits) resulting in an overall smooth, clean sound.  The microphone input transformer is interesting in that it is very small...sometimes referred to as a “thumb” transformer.  Usually a small transformer lacks low end response, as theory says it will saturate easily and thus attenuate peaks of low frequency signal.   Somehow the  thumb transformer in the MX-35 is able to pass low frequencies with minima..
