So let me get this straight. If the ID plate isn't brass it's a replica? As in the attached pictures.

He lived in Framingham right around the corner from me.

Thanks for the write-up Tom.
It looks like Victor was a BIG thinker and an outside of the box thought.

A colleague in town has giant Legacy Whispers driven by McIntosh 500 watt monoblocks. A magnificent system, but the Whispers are a very unforgiving speaker. Specifically, they expose everything in excruciating detail...the good and the bad. Some stuff sounds downright ugly.
Must be those solen caps in bypass Bill uses
My ref gear has that problem > bad recordings are BAD. The tube buffer can help on some but not all.

I'd go for the Legacy Focus SE if my AR's ever give up the ghost.

Mellotone is sold by Parts Express. Very nice material.
perhaps this is the "better grill material" you were referring to.

The AR94's I restored for my brother inlaw have that tweeter. I was over at his house and he was playing an Eric Burdon CD with an old Pioneer receiver. They sound quite nice.

I always like to recall this quote from Ken Kantor (from AK website)

I will always applaud the resourceful use of available parts-at-hand, but nevertheless, it must be asked: exactly why were the Solen caps previously deemed to be "incompatible"?....
AR Surround had tried the Solens in the UMR series cap for AR9 and 90. They are now being used in a parallel cap position where frequencies are shunted to ground.
There are some people who think all amps sound the same, not just caps.
-
Good job getting that goop off of the terminal posts. You sure made good use of the evil solen caps. Looks good and will last a long time. Happy listening.
-
Both 2 ohm resistors appear to be connected to the 100uF cap. So the other end/lead of the resistor needs to go to the negative terminal.
-
That goop on the backside of the binding posts looks like liquid nails. Ugghhhh. Butcher.........
They disconnected your woofer zobel.
It also looks like some early style of mylar caps (the ones that say Mexico).

Here's a crossover pic from my 91's. It might help as a wiring reference.

I think some technical info should be included on the more important break thru speakers. But yeah, the people involved. Pictures speak volumes. Good luck. Looking forward the the released product.
I ran into a member on the Emotiva website who made voice coils at one of the plants. He lives in NH I believe.

Kent, the metal cans in mine were also Callins. I think Sprauge was out of the picture shortly after the 9 series speakers began.
I think its hit or miss with the old Callins.

One of my 24uF metal can caps measured over 40uF.
Attached are the cap readings for my 91's
-
5 caps (4, 8, 24, 40 and 100). The 40uF is hidden under a resistor at the bottom of this picture.
Attached is a picture of the xover I did for my 91's
-
The 91 is no slouch.

$5 at a yard sale! Guess I need to go to more yard sales and get TP.
Thanks for the tilt info. I was guessing 10 deg. They look custom.
-
Nice looking stands. I need to make some for my 91's. What's the degree of tilt?
-
Nice write up John.
Why did you go with (2) 3 ohm resistors in series instead of (2) 12 ohm in parallel ?
-
Thanks Steve. I've had my eyes on the New Rochelle pair for a while. Xovers are untouched except for the addition of upgraded binding posts. New Rochelle wouldn't be too bad of a ride for me. A tad pricey.

Are these genuine AR 10pi or replicas?

OK, thanks fedeleluigi
What drivers were used prior to Tonegen? Did AR manufacture their own?
