[MRCA] Cord CD-267 for speaker LS-3

[Doran Platt]

Just to add another comment, I do not know what the CD-267 cable actually was used for, other than to connect an LS-3 to some receiver audio source. But, if it is to be used with many BC-312 and 342 receivers, the "Speaker 2nd Audio" output connector is jack to accept a PL-68. The connections from the speaker are tip and shield. The ring carries filament voltage from the receiver.  Otherwise, a simple PL-68/PL-55 cable will do. So, if the speaker is to be used with the aforementioned receivers, a cable with two PL-68s will be required. One can got audio from the PL-55 type headphone jack, but speaker volume will be lower.  Never figured why filament voltage on the speaker plug was used for. Will look again at the SCR-399 and GRC-26 books.

If no joy, be glad to put one together for you.  Note that the PL-68 end needs to be confirmed as some LS-3 spkrs have been modified as to connections.
