She does, no other explanation for her being here.
 
Got around to checking out the BIN 700 tonight. Faceplate kinda rough. Has ALL 2SD555's on the right channel and ALL DTS 411's on the left( ok 2 are 909's). When I said all I mean even the drivers are the same. This is a very early series I Ed tells me. No serial number, a silver sticker on the transformer saying made in Seattle. Teardrop meters, quite an interesting piece.

With a datecode of 7120 (20th week of 1971) these could be ORIGINAL outputs. Maybe Ed will chime in here. He had mentioned that Phase had scrubbed the DTS-411 OFF of the tranny's and then later started marking them as XPL-909's. I don't remember if he said they let any slip through without scrubbing the numbers off.
 
Another conundrum. Q1 is a TIS 93. Q2, Q3's are F2n 5550's, Q4, Q5's are 2N5401's, Q6 is an MPS5172. Protect transistors are RCA 40396p's ands N's. I have not seen this early a 700 that did not have the 1304, 05 transistors where the 40396's are.
 
Yes it does, it has 796 millivolts ddc for offset on the left and 385 for the right. It's rather noisy.
 
Probably leaky caps on that original board. Any idea when they shifted from Phillips heads on the tranny screws to the hex headed screws?
 
Nope, I'm sure Ed would know. Tried to get him to join. Pretty burnt on flaming forums as Joe mentioned awhile ago. I told him we could keep that to a dull roar and tap that historical archive of Phase linear history and anecdotal reference he's so funny at making. He really is a funny guy.
 
I would love to hear some of the stories that I'm sure he can tell of the goings on back in the early 1970s in the Phase Linear facilities.
 
I wonder if he can be bought?? Yo Sir Ed!!!! I'd even send this historical piece to ya!!
 
The cutouts in the heatsinks were chamfered, so it's quite possible this one was early enough that they were still drilling the chassis and heatsinks by hand.
 
BTW-Van Meter did not design MOST of the SErII stuff. AP only did the 5000 tuner and the real time analyzer. Terry Pennington was responsible for most of the Series II stufff,\.
 
Holy Crap!

Not a single shred of large bubble wrap or foam board in the packing as I see it. Very lucky that made it to you at all let alone in one piece.

Cool amp!
 
I was stunned, my wife on the other hand went into hysterics as she was the one unpacking it. She's still breaks out in spontaneous giggles.
