One thing that we need to check into and that is that Splitdorf Radio Co. beghan an association with Edison in June, 1928, at ffirst, manufacturing for Edison. By January, 1929, they had practically merged.. The acquisition of Splitdorf was of necessity to obtain their RCA license.The manufacturing operation was crude, and inadequate. The operation was moved to the Edison plant in West Orange. The R1,R2and C2 were Splitdorf designs that were put into production to get Edison into public hands. Later models were designed at Edison. This is from Alan Douglas' "Radio Manufacturers of the twenties", vol. 3. While nothing was mentioned about the C1, its cabinet design pictured in the Douglas book, has a strong resemblance to a Splitdorf top line model of that period. I sort of suspect that the C1 was a Splitdorf design. The C1 was priced at $1100.00, which was a lot of mazuma in that time.
The models C6 and C7 had been in production, and in 1931, a superheterodyne model was planned, but never built. ----- Original Message ----- From: "Bruce Mercer" <[email protected]> To: <[email protected]> Sent: Wednesday, May 03, 2006 4:08 PM Subject: [Phono-L] Theodore Edison > > ----- Original Message ----- > From: "Bruce Mercer" <[email protected]> > To: <[email protected]> > Sent: Wednesday, May 03, 2006 3:05 PM > Subject: Re: Phono-L Digest, Vol 3, Issue 109 > > >> >> >> >>> ---------------------------------------------------------------------- >>> >>> Message: 1 >>> Date: Tue, 02 May 2006 15:02:00 -0400 >>> From: "Dan Kj" <[email protected]> >>> Subject: Re: [Phono-L] The Practical Long Play Record >>> To: "Antique Phonograph List" <[email protected]> >>> Message-ID: <004a01c66e1a$e7120240$6600a...@new> >>> Content-Type: text/plain; format=flowed; charset=iso-8859-1; >>> reply-type=original >>> >>> So, did Theodore work on the Edison LP at all ? >> >> No. Charles picked up after T.A. retired in 1927, leaving him head of the >> company in that year.
