Philco Model 70 Superheterodyne Baby Grand Radio. Well-Preserved Antique Radio

yYou are looking at a Well-Preserved Antique Philco Baby Grand Model 70 Superheterodyne Tube Radio.  This radio has been displayed for thirty years.  We plugged it in on and off.  The radio has a very great, warm sound, just like the good old’ days.  Without the external antenna, it still picks up quite a few stations very clearly.  If I had to rate this radio’s condition, I’d say at say 8 out of 10, because of its age.  There is a bit of wear on the bottom edges.  The wood is still shining, the dials all work and seem smooth, the tuner light display is functioning.  This radio was extensively tested, it can play for several hours without any issues.  There is some very, very, very light hum, but when the radio is playing, it’s unnoticeable.  The grille and fabric is still in good condition, solidly held in place, although two small pieces of veneer have come off of the center of the front grille.  This entirely original, to the best of my knowledge, it has never been refurbished, it’s just an incredibly well-preserved antique.  As an old electronic, I’ll sell it as is.   I’ve had this for thirty years, I think it’s time to pass it on, in the spirit of Christmas.  Don’t miss your chance to grab it, you may never see its like again!

The Superheterodyne Book - Antique Radio Servicing - CD

Up for auction in CD-ROM format is that classic hard-to-find booklet from Radcraft Publications entitled "The Superheterodyne Book – All About Superheterodynes – How They Work, How To Build and Service Them" by Clyde Fitch, 4th Edition, 1940, 68 pages.

This book was prepared to present in simple and clear terms as possible the theory, design and construction of Superheterodyne receivers.  The purpose is to give the reader a handy reference book and guide that will help him in his work, whether he is interested in servicing superheterodynes or plans to design and build them.  In any event, a thorough knowledge of the subject will be found the shortest and most sure route to successful receiver performance.

The superheterodyne has always been considered the supreme type of radio receiver.  It is more complex and versatile in its actions than other popular types of receivers, and for this reason, has always been found highly fascinating by those who have studied it.  However, a highly technical knowledge of all the various components of the supergheterodyne is not absolutely necessary for the practical man; therefore, only sufficient data of this nature to meet practical requirements are given.

The main bulk of the book treats with modern receivers of conventional design (as of 1940).  As many varieties as possible of these modern receivers are included so as to give the reader a breadth of vision and not hold him down to fixed rules.
