Blaupunkt Arkansas stereo tube radio restoration - Part 1
This radio comes out of a Radiogram unit. For or ease of restoration, it was removed from its housing.
It is actually quite a 'modern' set, dating from 1963 when tube radios were on their way out, being replaced by transistor sets. Coincidentally, this was my birth year.
It features stereo reproduction of any connected line inputs, like a gramophone or tape deck, and uses an interesting dual-purpose output tube, the ECL86. This valve includes a triode and a pentode in one 9-pin housing, allowing for the preamp and power tube functions to be carried out in one tube. There is one for each channel, feeding two output transformers to produce the audio output through dual sets of speakers fitted in the radiogram unit.
This first look actually went further than I expected, as I manage to test the output transformers and the power transformer. Both are good, so we have a viable candidate for restoration.
Hope you enjoy the series.
