Which are the photo-cells in this unit? Do they clone the T4B?

They're Vactrols......under the washers.

Nicely loomed and formed wiring....

Cool! Under the metalwashers? Why do they hide them under there?

Love those hard right angles.

The Vactrols in the E_L_O_P are Perkin Elmer VTL5c2 and the side chain is just an LM386.

Yeah, but it would be quicker to use ordinary strips/cable binders. Also easier to replace a wire later. I think that's a significant cost factor, since those puppies are handassembled by people who get a nice pay per hour.

LM386? Isn't that a small poweramp chip?

EDIT: Yes it is?!

Kubi, the first and last pic you posted look very crappy and 'pixled' to me.. :?

sismofyt · « **Reply #9 on:** June 27, 2004, 09:50:18 AM »

Seriously, those two pics looks supa crappy. I can't see nuffin'.. much worse than the originals.. :?

Strange, I can't see anything on the originals.
I guess my monitor declines.

I guess my monitor is crappy also - the originals just look like black squares to me...

Best regards,

Well, the originals do look dark to me, but perfectly detailed. Kubi's look like they've been converted to 2 bit resolution :? :shock: FYI, my computer is a @-computer (yes, that IS the name) laptop with a 15" screen, brandnew..

OH MAN...

Why do I have a feeling someone is going to stop by pissed off...

I mean how dare anyone pop the lid of a manley product :green:

I can not read the IC but I don't think it is a 386 might it be a 324 quad?

sismofyt · « **Reply #14 on:** June 27, 2004, 11:18:43 AM »

Kubi, you cloned the Manley pic :shock: :wink: :green: ..

Yeah, it's probably a quad opamp. Using a poweramp to drive a LED is a wee bit of overkill me thinks :?

Gus · « **Reply #15 on:** June 27, 2004, 12:40:34 PM »

a 386 could be used to drive an autotransformer like in the la3

In the middle ages, people were afraid to say the devil's name because the belief was that if his name was spoken, he would appear.

chrissugar · « **Reply #17 on:** June 27, 2004, 05:15:30 PM »

Gus and Sismofyt, belive me it is an LM386.
In the e-l-o-p the signal that drives the LED [in fact two leds, antiparalell and the photoresistors are conected paralell too] in the VACTROL is audio signal ,not a rectified voltage like in normal compressors. The advantage is that it will behave like an LA2A because the time constants are dependent on the VACTROL. The only disadvantage is that you can't modify attack and release time constants. But this is the trick, you don't need this. The LA2A has only two knobs ans sounds great.

I don't quite understand you...?

I do the same in my opto comps, use the LDR's build-in attack/release times a' la LA2A. But I don't use a poweramp chip to drive my LED!

Sooo, why do they use an LM386? There's gotta be more to it than just current drive?

Gus, since they use Vactrols, they're just driving a LED. No need for step up trannies like in the LA2A or LA3A..
