Here is what I believe to be perhaps the rarest combination of parts put together at the factory that you could ever imagine.Â I have looked this over real close and I believe it to be all original.Â Read on to see why I think this is so special.Â Â
First of all, I bought this at the Michigan Antique Radio Club Extravaganza in 2006 and thought it was unique because of the battery door cover.Â It has the flared bottom seen only on Royal 300’s.Â So I figured that maybe someone swapped a maroon 300’s door and put it on the 500.
The front view shows the knobs of a second generation 500B, but the pointer on theÂ plasticÂ dial indicatorÂ is black, which indicates an early 500B.Â A few ofÂ these early 500B’s with black lines have handwired chassis even though the knobs would indicate a printed circuit board.Â But did this one did have a handwiredÂ metal chassis?Â Yes!Â Yeah!
Â The label on the battery door was not for a Royal 300 like I thought, it said the chassis was a …….what?Â Can this be right?Â Â Â
Sure enough,Â there were 7 beautiful blue Raytheon transistors looking at me as this set was equiped with the rare 7XT40Z chassis.Â No one knows for sure just how many of these handwired Raytheon chassis were made, but based on combined knowledgeÂ from other collectors, auctions and conversations, if it was any more than 1-2% of the 100,000 handwired units, I would be surprised.Â
And how many hybrids were made?Â A hybrid was made during the transition from handwired boards to printed circuit boards.Â ApparentlyÂ the supply of all the parts did not balance during this time, so some mixed models were made.Â But another strange part of this radioÂ is that the serial #Â is 33,684 which would indicate that it was laying around for several months.Â Â The other hybrids that have been reported have had serial #’s ranging from 90,000 to 121,000.Â Very strange.Â
The final comment I have to makeÂ about this unique radio is that it appears to be all original and it plays like a champ.Â Has anyone else encountered anything like this before?Â I would be very interested to hear about it.Â Anyway, enjoy the pictures.Â Don’t forget to click on the picture twice to get a larger than lifeÂ close-up look.Â GaryÂ Â Â
