1954 ar-1 pictures of back of speaker

[jeffry]

I have been looking for any pics of the amp hookup"1- 7" and the"abc" hookup on a vintage ar-1.

[genek]

Do you just want to see what they look like, or are you looking for hookup instructions?

[jeffry]

I am looking for pictures please.

There's a photo of the 7-terminal connection in the library at:

Here's one of the ABC connection.

[tysontom]

Connection of the "A-B-C" portion of early AR-1s:

For use as a complete two-way system, connect strap between terminals A and B. For use as a low-frequency speaker only, connect strap between terminals B and C.

Connection of the input terminals "1-7" on early, pre-level-control, AR-1s:

Input terminals are #1 and #3. Strap on terminals #1 and #2 is for 4-ohm operation, remove strap to put internal 4-ohm resister in series with woofer to make 8-ohm system. For normal high frequency level, connect straps between #4, #5 and #6.

See attached image for more detailed instruction on the high-frequency adjustment.
