Jason's Phase Linear P3600

[laatsch55]

While we shake down Johan's Wopl 1000, we'l take care of this pre. Came in for BUZZ. Recap, op-amp swap, eliminate the ceramics, de-oxit, and whatever else it takes..

Not much in there, and that's usually a good thing...Mark wasn't lyin about this one, she's way cherry...WOW!!

I couldn't believe it when I got it how clean it was. And had all original paperwork also!! In a phase linear box even!!
glad to see it on the block! Thanks lee

What the hell does that ribbon looking stuff do??

 

[laatsch55]

Ribbon cable..

 

[Skynyrd77]

I've never seen that stuff before! As you can tell I'm no tech lmao..

 

[laatsch55]

Me neither..

Ok Sir Joe. This 3600 has NE5532's and RC4558's. I have the OPA 2134's and the LM4562's and TLE 2072's.

 

[laatsch55]

Need a scan of the schemo, you should probably peruse it anyway..

The parts list says there's another one. Z6 is 78L12

Interesting on the 3800 they use different ICs for the different phono inputs. MC = 5532. MM=5534. In the notes on the 3800 schematic is says Z1-Z4 are
RAY4156,NEC4741 or equivalent.

 

[laatsch55]

78L12 sounds like a voltage regulator... That's why I wanted Joe to see the schemo, perhaps he could shed some light on why the MM section was treated differently than the MC section...

 

[Skynyrd77]

Awesome getting underway!!!

Yep, picking the man's brain has yielded excellent results in the past.


Doug , you like your 3600?

 

[Skynyrd77]

Hey can you reply to my ignorance in the 700b thread lee. I feel like a idiot asking but will never learn without lol

 

[laatsch55]

jase the only dumb questions are the ones not asked....

I bought the 3600 ($130 + freight) + a 3800 ($212 + freight) within a couple days of each other in Feb.
The 3800 has a spot that requires some paint repair. Haven't gotten around to fixing that yet.

I actually haven't hooked either pre up yet. Just plugged them in and powered them up to see what would happen.

Still using the 3300 you did the work on.

Doug, it appears the 3600 is even easier to work on than the 3300. You can do your 3600 I'm a thinkin...

 

[laatsch55]

From what I've seen of them , they are definately sleepers...at that price for damn sure...

Does it suffer the same "trace lifting" as the 3300?

 

[laatsch55]

Haven't seen the solder side yet Doug, should befoe the night's out...
