Siemens TF78/30 and TF80/30 in use also by a wide range of Blaupunkt Car Hifi
Arround the years 1957 - 1963 this transistors often to find in power amplifier stages of hybrid car radios, mostly from the German brands Blaupunkt and Becker as to see here:

2N176 use in Single Ended Power Amp Stages in Vintage Motorola Car Radios
Motorola gold plated Germanium power device 2N176 and related types made for Motorola Car HiFi devices - used in single ended pure class A audio power output stages. This was complete new for me - very interesting fact. Also new for me was the fact, that several years still tubes was used for the AM/FM receicer part. The solid state parts are only to find for the power amp section and for the dc/dc converter (so called "hybrid" versions). Full transistorized/full solid state car radio devices first in the mid of the 60's cheaper than combination of transistors and tubes. I think, this and the appropriate HF behaviour was the main reason therefore.

Bendix TO-3 in their Car Travel Tuner - Solid State Audio Amp & Valve AM/FM Receiver
Bendix Hybrid Car Radio - Solid State Audio Amp & Valve AM/FM Receiver; Bendix call them also "Pushbutton Radio" and "Travel Tuner" (new terms for me)
In opposite to Motorola's versions here I note, that the solid state output stages are push pull but also not OTL. Very interesting is the mounting place of the TO-3 power device. The brand "Bendix" in German is very rare and hard to find. Here some pics and informations Bendix Radio Foundation http://home.xnet.com/~otis/Lincoln/RadioService.pdf (Service Manual Lincoln Travel Tuner 95BH, R95BH) http://www.bendixradiofoundation.com..._IllusList.pdf (Bendix Car audio overview) Bendix Radio, Baltimore Radio Catalog http://home.xnet.com/~otis/Lincoln/RadioService.pdf Antique Radio Forums :: View topic - 1962 Mercury Car Radio Schematic Needed OLD BENDIX RADIO TV AUTOMOBILE PHOTOFACT SCHEMATICS 1965 Ford Radio - Ford Mustang Forums Early 64½-66 Mustang page of Klaus > Early Mustang Picture Gallery > Parts & Pieces > Special 64 1/2 Mustang Parts Bendix Transistors TO-3 Transistor Museum Early Germanium Power Transistor History by Joe Knight Bendix Results for Semiconductors:Vintage Also in Home HiFi components like KLH Model Eleven the brand Bendix is not often to find: Overview of Brands and Models from first Solid State Audio Amplifier Components want.

Bendix more pics
Bendix, more pics. No transistor (power devices) databooks to find. Who can post some cover pics?

OD604 - Inside in Akkord model: Trifels, Supplement to post 16
this transistor works in a universal radio for travel/portable and car audio application, launched 1958 (one of the first fully Solid State radios - I think). German price 1958: approximately 500 DM
