What model and year are my A7s?
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 :)

I also posted a video you will want to see on youtube, see next post

Nice Video! How much power does that Imp Amp put out?
Re: What model and year are my A7s?
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.
Re: What model and year are my A7s?
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.

they do have the 500 Hz crossover, it's
N-500-G DIVIDING NETWORK
I opened it up, the 15" is a 416-A, 16 Ohms, green. It has 21184-2 on the cone and 391836 on the frame

Does seem to be mostly 5/8" plywood construction.
So I guess they are 1968 A7-500?
Is there another model # for the cabinet type?
Thanks!
These have labels on the back JOLIET JUNIOR COLLEGE
and another JC DIST 525 2005
Oh that Z Vex IMP AMP is 1 watt, proof of Altec's efficiency claims.

They are really in nice shape, very nice specimens !! ;)
If your talking about just the cabinet it is a 828.

5/8 ply and half backs = 825. 828 cab was born around 1970, maybe late '69 so the OP's are just a bit early to qualify.

Nice decibal level for one watt! I would agree with Bowtie's estimate of approximately 1969. The last three digits of 391836 (stamped on your woofer) is the date code on your 416-A woofer. The 8 is the last digit of the year of manufacture (1968) and the 36 signifies the 36th week of 1968. So your woofer was manufactured in September 1968--your A7-500's were probably assembled around 1969.....
Re: What model and year are my A7s?
I'd wager those A7's were in service somewhere by the end of November '68. Those are all very "mainstream" Altec components, and at that exact point in history i don't think those components saw much in house shelf time at all once the glue was dry.
It's just my WAG after all, but there sure is a lot of that vintage Altec still in circulation today which seems to indicate that "product" was sellin just fine.

September of '68 was the beginnings of Led Zeppelin.
Time to crank some up! :Trauma:

I really like their more "acoustic" stuff on the VOT's, think stuff like "Gallows Pole"..........................
