Default 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.

Default 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

Default 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
