First Phase Linear Ad (Audio December 1970)

oldphaser said:
Here is an ad which I believe was first used in January 1971 in Audio magazine.

If so, I would find this interesting since it has the Seattle, WA address (in the Richmond Beach neighborhood of what is now Shoreline, WA).

Considering that there is a several month lead time in advance of an issue coming out, the amp was either a bridge amp, a Kelly DeYong amp or an empty chassis at the time. The PL0171 pc board was not used until sometime after January 1971.

By the way, the Seattle address no longer exists. I believe they were using the bottom floor or basement of an old grocery store (at the address noted in the ad) which predates their move to the bottom of the grocery story at 405 Howell Way in Edmonds, WA. If my memory serves me correct, Steve Johnston, Greg Johnston and another friend (whose name escapes me) were living down the street (from this location) at what was once the Handy Spot Market. Bob was living near "Firdale Village" a couple miles away.

I stand corrected. The first ad ever to appear for a Phase Linear product appeared in Audio magazine December 1970. see page 88
(Can you imagine receiving a Phase Linear 700 for Christmas in 1970?)

I really appreciate you putting all this out here for us Ed, so much coolness
 
VU Meter (Wikipedia)

Dean referred someone to me a couple weeks ago who has some issues with some Dixson VU meters used in a 700B. I suggested he contact Larsen Metercraft for repair (as they were the only company I was aware of 18 years ago that advertised meter repairs) and get back to me. Tonight he called me back. They currently have (2) meters. Apparently they are trying to baseline at least one of them which they believe may be a 1mA full scale meter as opposed to a true VU meter. They have never seen another meter like this one. They have heard of Phase Linear before but not seen any VU meters used in Phase Linear amps.

I gave my original Dixson catalog to Dean years ago and only kept a copy of the page with the 520T on it. I went searching for my copy of the Dixson 520T spec sheet in some of my boxes and back-up hard drive to no avail. I will keep trying. Hence all my recent posts on VU meters used in Phase Linear amps.

As I am trying to determine which Phase Linear VU meters were true VU meters and which ones were simply 1mA full scale meters....
I am including this reference:

Midland 23-721 VU Meters (used in early Phase Linear 400 Series 1 Amps)

Here are some scans taken from 1974(?) Midland International catalog(s).

NOTE: As some of you may recall, I have stated previously that the Midland VU meters had to be one of the most unreliable VU meters Phase Linear ever used.
