What model and year are my A7s?

**analogmike** · July 10th, 2010, 08:21 PM

Hi,

I got a pair of these recently for a sound system for my basement music room. I think they are A7 but not sure which version or when they were made.

I think 1968 or 1978 due to date codes of "8" on the speakers. Has
802D 16ohm 15", horn drivers 391831 836 416.

Any info appreciated, thanks!

p.s. this is how they showed up:

You leave off important details...

Woofer frames? Old almost certainly 68. Newer 15 frames were phased in starting around 71 or so. 12's had them earlier.

New, 78.

My guess is 68 due to the 802D, G was current in 78. Again, with old frames that would be certain.

Analogmike, after seeing PT posing with one of your FX boxes i gotta ask: Who are you?

Did i also catch a pic of Vinni Moore, and maybe another of Trey Anastasio?

By all means, post up some pics of your Altecs, you're sure to learn far more than you ever wanted to about them here.

I think there'll be at least a few folks here who will be very interested in what you do/build as well.

Thanks guys, you can see the pictures below.

I don't know what a frame is on those but the picture should show it.

My company does make guitar pedals for everyone from Aerosmith to ZZ Top

Nice Video! How much power does that Imp Amp put out?

Hi Mike, OG was talking about the frames on the woofers.You can give a more accurate age on verifying the frames.:welcome: You can put that amp in your pocket

That shows how efficient the Altecs really are.:2thumbsup:

Regards !!

1968 is my guess. Looks like a 5/8" plywood cabinet.

So, they're A7-500's, not sure that question was ever really answered.

Agree with the other posters that '68 is the vintage, green paint on the components is a strong clue, they didn't use it very many years past that point.
