An ad printed on a newspaper (DATE:1949) of a
Blaupunkt model36K
(I don't have this one in my collection yet. I am looking for!)
Front page of the operating manual of a Philips
BX380A (I have this
great radio of course! A very rare thing)
A diagram from the same manual which shows the
inside view and
tube complement of this radio.. The output tube EBL21 has unique
sound characteristics (really hi-fi)
Another diagram from another source which shows
"how to construct
a good antenna system" for the classic radio (DATE:1941)
