Gates Model 30 Studio Console
A broadcast console that stations bought, used hard, and then sold for $250 out of a West Virginia transmitter room.
Overview
The Gates Model 30 is one of those pieces that survives almost entirely in the classified columns of old broadcast trade magazines rather than in catalogs or spec sheets. What the record actually shows is a studio console that moved through real stations — and the paper trail is mostly made of engineers trying to get rid of one. A 1963 classified ad in Broadcasting offered a Model 30 "now in use" for a first check of $250, FOB New Martinsville, West Virginia, from the chief engineer at WETZ. That single line tells you most of what's knowable: it was working gear, it was cheap on the secondary market, and stations treated it as furniture to be liquidated when they upgraded.
The Model 30 turns up repeatedly in package deals alongside the rest of a station's air chain. Engineers at WNEX in Macon, Georgia listed one in the same breath as a Rek-O-Cut B-16-H turntable, a Presto 6N cutting table, a GE BC-3-A transmitter console, and a 10,000-watt Western Electric FM transmitter — the whole plant offered at a discount as a bundle. That's the context a Model 30 lived in: not a standalone hi-fi component but one rack in a room full of broadcast iron, wired to turntables, cutting lathes, and transmitter consoles.
Collectors chasing one today should understand what they're getting into. The Model 30 is a broadcast studio console from the vacuum-tube era, and the surviving documentation is essentially classified advertising — no published spec sheet, no service manual excerpt, no period review with measured performance. There is no confirmed production run, no original list price, and no documented circuit topology in the available record. What exists is proof of use: multiple stations advertising working units between roughly 1962 and 1963, which at least establishes that the console was in active service in that window.
The name itself is a trap. Searching "Gates Model 30" today surfaces a great deal of material about a Model 30B one-third-octave real-time audio spectrum analyzer, advertised heavily in Mix through 1987 and 1988 as a handheld analyzer for studio, live-sound, and sound-contracting work. That is a different product entirely and has nothing to do with the broadcast console. Mix (November 1987, p.39) described the 30B as a professional third-octave analyzer aimed at checking room response and setting EQ — useful context only insofar as it warns a buyer that the model number is shared across unrelated Gates-era product lines. Anyone hunting parts or documentation for the console will wade through analyzer listings first.
What can be said with confidence is narrow. The Model 30 was a Gates studio console — the ads call it exactly that — and it was in daily broadcast service long enough that stations were still running them into the early 1960s. The WETZ listing describes a unit "now in use," which is the most reliable kind of evidence: the console wasn't a museum piece when it was sold, it was working air-chain equipment. Beyond that, the honest answer is that the documentary record is thin, and a buyer should treat any listing claiming detailed original specifications with suspicion until a service manual surfaces.
For the collector, the appeal is archaeological rather than audiophile. This is a slice of American broadcast infrastructure from the tube era, sold out of transmitter rooms by chief engineers who knew exactly what it was worth on the used market — which, by 1963, was a few hundred dollars. That's the number to keep in mind. A Model 30 is interesting because of where it sat and what it did, not because anyone has ever measured its distortion or published its frequency response.
