Pultec 1977 Full-Line Catalog

Download the complete twelve-page 1977 Pultec outboard audio equipment catalog:

DOWNLOAD: Pultec-1977_catalog

Units covered, with text, specs, and photos, include: Pultec EQH-2, EQP-1A3, and MEQ-5 equalizers; Pultec HLF-3c and HLF-26 filters; Pultec SP3 and MH4 mixers.

Until I saw this catalog I had not realized that the original Pultec production run had extended into 1977.  These are the solid-state Pultecs, not the more coveted vacuum tube units that trade in the $5000 range, but AFAIK the actual equalization stages are the same as in the earlier tube units.  I have never scratch-built a Pultec clone, largely because the idea of hand-building the multi-tapped inductors always seemed a little daunting to me.   I recently found myself in possession of a large batch of various MiniDuctors, though, and I am wondering if these can be put service in a Pultec-type circuit.  The mH values are very close to those in the putlec schematics, but I cannot find any reference online to anyone building a Pultec using MiniDuctors rather than a large coil-wound inductor.  Anyone have any idea about this?

More outboard gear of the early 60’s

The Pultec range of 1961: the Pultec EQP-1S program equalizer, EQH-2 program equalizer, HLF-3C high and low pass filter set, MB-1 mic and booster amp, and Mavec micpre/EQ unit.

Pultec equalizers have enjoyed fifty-plus years of popularity among recording professionals.  Much like the first several compressors released by Universal Audio/UREI, they have never really gone out of style.  And if vintage Pultecs seem expensive these days (and they no doubt are…), remember that there is an inflation factor of 11x from 1961 to 2012.  So the value of these pieces has more or less simply risen with inflation.

The Pultec MEQ-5 and SP-3 Stereo Panner of 1962.  As unlikely as it might seem, the ‘pan’ knob was, at one time, a new and novel concept.

Ok so these are not outboard so much as inboard but you get the connection.  The Langevin EQ-252A, EQ-251-A, and EQ-255 filters of 1961.

Above: the Universal Audio 175B limiter is announced.  The 175B is quite similar in operational principle to the Altec 436/8 and the Gates Sta-Level but the UA is far more sophisticated.  Just a really smartly designed piece of AFAIK, it was sold like shown, with no top cover.   gear.  Retro Instruments currently makes a reissue of this classic piece (but with a top cover).

Above: an inexpensive studio echo unit of the early 1960s: the Telefunken Echo Mixer. It is a spring-reverb unit.  Click this link for an audio demo.   Apparently used by Klaus Schulze on his “Irrlicht,” which is one of my favorite records.
