Since I work for White's now, I'll allow this to be posted. Enjoy!

Carl,

After glancing at this a little, a few questions...

What does "Selected" mean on some of the chips? Where these components pre-screened to some level of performance?

There are a couple of cross-out, are the cross-outs the correct values?

Many thanks for posting this, these were (are) GREAT analog detectors!

I call it "sifting." My bet is temperature range characteristics for stability. But that's just my opinion.

One of the opamps appears to be selected for offset voltage. The 4053 is probably selected for switch resistance matching.

Have no idea. Whoever scanned this probably made the mods.

could someone post the exactly dimensions of the PCB , with holes from the 6000....


thank you very much



someone at the russian board is doing a modifiaction of the 6000

Anyone knows how to calibrate the 6000 DI PRO SL for factory settings?
Got a used one but the owner tuned them wrong i think.
Are there any Test Points???

Steffen,

Contact Todd at [email protected] and see if he can send you a copy of the calibration procedure.

Excellent. I'm looking on it for the meter circuit and don't see it.
is this the same schematic as the one for the 5900/4900 board? I am looking for the meter VDI components. I assume the 5900 board is the same as the 4900, i
s that true?
