Telefunken RC-300 3 motor direct Multidrive Stereo Cassette Deck, 1980, made in Germany

The RC 300 is arguably one of the best, luxurious...and most expensive tape decks Telefunken has ever built. No tape deck before or after had a longplay option, or a three-motor mechanics. The drive mechanism is the MultiDrive mechanism that was developed by Papst, a company that is today still known for the quality of their fans. With a separate motor for the capstan and each reel, there is no need for belts or rubber rolls, all controls are done electronically and there are much fewer parts that can fail.
The RC 300 was part of Telefunken's T 300 high-end component system, and it has a remote control input that allows the drive functions to be controlled via the RP 300 pre-amplifier.

Hilton Sound (Hans G.Hernel GmbH + Co KG) SOFTLINE SL 400, 1975?, made in Germany

Chronicle: January 1, 1948Family Hennel founded "Heco" in Schmitten / Taunus. (Other sources say 1949) First, only tube radios are produced.1965The first Heco HIFI loudspeakers, the B310 are produced. They were developed by the still young engineer Wolfgang Seikritt. SourceTo the 1970sHans G. Hennel dies. It should have come to disputes. A bust of the firm threatens. Quelle1972Heco is sold together with factories in Remscheid and Schmitten and including name rights to the British Rank-Radio.
But a small part of the family business remains in the family, including part of Hans G. Hennel's daughter (or woman?) Suse Hennel.192 Three employees leave Heco and found CANTON. Founding members were Hubert Milbers (Managing Director), Otfried Sandig (Marketing, Sales), Günther Seitz (Technology) and Wolfgang Seikritt (Development) Source 1975Heco Hennel & Co Berlin, owned by Suse Hennel. The company belongs to the holding company H. Dahl KG, Hamburg. Also included are Visonik KG, Dahl Elektronik KG and CEC Europa GmbH. Visonik was known for its compact David speakers. SourceCa. 1975Each loudspeaker developer from Braun changed to internal disputes to Heco and Canton. SourceAb approx. 1975Loudspeakers under the company name Summit with reference to "A product of Hans G. Hennel GmbH + Co KG" are produced. The production site is Usingen. (However, there are also summaries from Summit / Wehrheim). Since they do not bear the designation "Heco", it remains to be assumed that also this company still belongs to the family enterprise and not to Rank. In the point, of course, I can deceive myself! Comparisons in the 70s: There are also loudspeakers under the brand "Hilton Sound", originally marketed by "Elektroakustische Geräte H.Hilgers GmbH & Co. KG", marketed (Whether only marketed, or also manufactured I do not know yet). They also bear the words "A product of Hans G. Hennel GmbH + Co KG" (without location details). The loudspeakers with the brand names "Planet" and "MR Service" and loudspeakers without further brand names (eg: TS 7007, GTS 1020) bear the same designation. 1980 - 1986: still missing1986Heco is acquired by a German entrepreneur team. It goes up again. Quelle1986 - 1996: still missingEnde 1996Heco GmbH (Taunus) and Heco Electronics GmbH report insolvency and are taken over by the American Recoton Corporation in December by RECOTON Holding GmbH. Heco now operates as Heco Audio (Produkte) GmbH in Pulheim. QuelleSommer 2003Support of RECOTON Holding GmbH by AUDIOVOX old-fidelity

Linn KAN MK1, 198?, made in Scotland

All Linn serial numbers are Scottish serial numbers, there are no US Linn serial numbers. Linn Products are made in Scotland.

These Kans can take both banana plugs and binding posts.

The Mark 2 was biwireable.

The biggest difference between the Mk1 and Mk2 is the fact the Mk1 has internal damping, which is why many people think the Mk1 is better. Of course Mk2 can be modified with internal damping, plus you get all the advantages of all the other internal upgrades Linn made to the Kan 2.
