Teac PB-64
A hundred-dollar box of jacks that quietly made every Teac multitrack rig usable.
Overview
The PB-64 is a patch bay — sixty-four points of point-to-point connection, built to untangle the cable snake that grew out of any serious Teac multitrack setup. Teac's own advertising was refreshingly blunt about the job: it "takes any combination of 64 inputs and outputs for just about any system interfacing," a claim that reads less like marketing and more like a plea from anyone who had ever stared at a pile of RCA leads behind a Model 2A console. The connection design accepts standard RCA phono plugs, and the front panel carries a textured surface specifically so you can write on it — labeling is the whole ballgame on a patch bay, and Teac knew it.
The price was about $100 at your Teac dealer, with the usual caveat that actual resale prices were set by the dealers themselves. That figure matters more than it looks. A hundred dollars sitting between a four-channel tape deck and a mixing console is the cheapest insurance in the signal chain, and it explains why these things turn up in so many period studio photographs — often with a strip of masking tape and a Sharpie scrawl across the top.
What the PB-64 actually did was make the Teac ecosystem behave like a studio. The company pitched its multitrack line as a way for serious musicians to get "many of the important elements of the studio experience but without the studio bill," and the patch bay was the connective tissue in that argument. The same 1978 campaign that introduced the A-2340SX and A-3340S four-channel decks, the A-6100 and A-3300SX-2T mastering decks, and the Model 2A console with its MB-20 meter bridge listed the PB-64 and its cables as the accessories that "help organize the process." Organize is doing a lot of work in that sentence.
The patch bay's second life was as a promotional sweetener. Through early 1980 and again in early 1981, buyers who picked up an 80-8 reel-to-reel and a Model-5B console between January 1 and April 30 were handed the Model-1 monitor mixer, the MB-20 meter bridge, and the PB-64 patch bay as part of a limited bundle — Modern Recording (February 1980, p.37) ran the offer, and the same promotion reappeared in the magazine a year later. Sound Arts (March 1980, p.25) carried it too. That tells you something about how Teac viewed the PB-64: not as a prestige item, but as the thing you needed the moment you owned more than one piece of their gear, worth giving away to close a sale on the big stuff.
By the early 1980s the PB-64 was a catalog staple rather than a headline. British dealers listed it as the "PB-64 64 way Patch Bay" alongside the PE-40 parametric EQ and the rest of the "Enhancement Series," and it shows up in used-stock clearance lists at £40 — with a bundle of 32 phono patch leads thrown in for £16. One dealer's inventory even renders it as "PB64 patchbag," which is either a typo or a confession about how these things were actually transported.
Whether it's worth chasing depends on whether you already own the RCA-terminated Teac gear it was designed to serve. On its own it's a well-made, unglamorous utility — which is exactly what Teac built it to be.
