Stamped serial numbers

I decided to hotrod my last AR-5 acquisition so I've been working on the cabinet and today I was hand sanding the back after removing the labels and after most of the crud was off there was still a spot or two. One of them happened to be the serial number of the speaker stamped in the wood.

And here all the time I thought AR was too lazy to do that!

Uh... can you post a picture of that stamping? "Stamped in the wood?" Do you mean a rubber-stamp number or a die-stamp indentation? The cabinet vendors used die stamps for their cabinets in some cases. AR used a rubber stamp on inside surfaces at some times, and KLH also used to use a rubber stamp to put the serial number on the inside of the early cabinets.

The paper tags are the only place I've ever seen serial numbers displayed on the classic AR's. I have seen two different rubber stamps used on cabinet interiors, and this pic shows the only place I've ever seen a die stamp used on the cabinet exterior - - in this case, noting AR-3 cabinets. (Nice joinery, eh?)

Tom,

They are die stamped under the serial number paste-on label from early 1970 production -- 11,000+ serial number range.

I'll try to get a photo for you.

Okay, I'm supposed to be working on something else at the moment, but hey... here is a photo of the die-stamped AR-5 serial number located under the pasted serial number label.post-173498-0-04392500-1412370374_thumb.

For the doubting Thomas' out there, here is the label. And remember, don't open your cabinets, you will void your acoustic seal ;)

Tom, what does the prefix letter stand for? Cabinet source? Crew?

Roger,

Very good! That is the first I've seen of that die-stamped serial number! Maybe I've seen it and didn't pay attention to it, but I've looked in a lot of cabinets and never noticed it to my knowledge. Maybe since it was under the label I didn't pay attention to it.

The letter in front of the serial number stands for the chronological placement in the product line. For example, "C 06740" would be an AR-3, the third AR speaker, with the serial number following. AR did not use this all the way through every series, to my knowledge.

Thanks!

--Tom
