Grundig TK-12
A reel-to-reel that Grundig sold in guineas and priced like a good instrument - and that a British cinema put in a shop window.
Overview
The TK-12 is a Grundig reel-to-reel tape recorder that shows up in British advertising of the period at 70 guineas, less microphone. That figure anchors everything else about the machine. 70 gns. was serious domestic money in the late '50s and early '60s, and Grundig's British arm priced it that way deliberately. The copy in the trade press leaned hard on the idea that a tape recorder was a musical instrument rather than a gadget. One advertisement built its whole pitch around a professional musician who wanted to hear his own playing played back, and who claimed the dealer demonstration alone would have sold him the machine at twice the price. Another version of the campaign took the angle of a listener whose record collection had gone stale, arguing that tape lets you wipe the slate clean and start again.
Mechanically, the TK-12 is a mono machine. A dealer price list in Studio-Sound (September 1971, p.50) lists the Grundig TK12 twice, at 35 gns. and at 88 gns. depending on configuration, and files it under the mono column. The four-track Philips machines are listed separately. The 35-guinea entry matters if you're chasing one today. The model clearly sold in more than one trim or bundle, and the "70 gns. less microphone" figure from the advertising is the fully kitted domestic package, not the bare deck. The price paid probably varied a lot depending on what came in the box.
The TK-12 also turns up in odd places. A trade-news item of the period describes Grundig loaning a TK12 to the production of a British mystery-thriller called "Timestip," starring Gene Nelson and Faith Domergue. In the film a man rescued from a river answers questions before they are asked, and the recorder was the prop that proved he was running seven-and-a-half seconds ahead of time. The same item urged Grundig dealers to put stills in their windows and demonstrate tape recorders in the foyer after performances. It says the TK-12 was positioned as the friendly domestic machine a cinema audience might recognize, not as lab equipment.
The TK-12 sits in a long Grundig reel-to-reel lineage. A 1964 Studio-Sound notice from Tape Recorder Maintenance lists drive belt sets for the TK1, TK5, TK8, TK9, TK12, TK14, TK18, TK20 and on up through the TK60. The belt is the part that fails first on any of these decks, and it was being catalogued as a spare while the machines were still current. Anyone buying a TK-12 should assume the belt is either perished or already replaced. Check the indicator belt too, since the belt sets were sold complete with one.
Documentation for the TK-12 is patchy compared with Grundig's bigger radio lines. No service manual, no independent lab test, and no confirmed production dates have surfaced. The machine is known from advertising, dealer price lists, and the occasional press mention. The specifications that would let a buyer judge one against a contemporary - tape speeds, frequency response, head configuration, dimensions - are not recorded in the sources available here. That doesn't mean the TK-12 was a modest machine. The paper trail runs through retail listings rather than review columns, which is typical of Grundig's British-distributed tape line of the period.
For a collector, the appeal is partly the machine and partly the campaign. The "Why I bought a Grundig" advertisements are among the more charming pieces of British hi-fi copywriting, and the TK-12 is the model they were written around. A working example with its original microphone and a copy of the advertisement makes a tidy little display. A non-working one is a project, and the circuit is undocumented.
