Hi ThiagoFaraday,

thanks for sharing the gutshots.

I traced the PCB imgages to create a PCB etching template.
I could not trace all conductors, because some are hidden behind the parts.
Please could you check the conductors and insert the missing ones on my drawing.
Next, I would like trace the connections and draw the schematic.
The bright conductors are on the componet side.

Hi Manfred, wow you did an awesome work on that pcb! thanks alot! :applause:

and sure, I will open and check again, Im having issues to the values on the resistors. the colors are confuse to me and some I cant mesure.

But I think its a metter of time to figure out.

Hey Manfred, here I just erased one bright, and make the missing traces with fine lines on the same color as you did, but my traits turned out really ugly. :oops:
sorry for that.

roberttomasz, I only see here R5 connected to R4 and to collector 2N4401. C2 its connected to emitter :hmmm: . I will correct that. thank you roberttomasz!

Hi ThiagoFaraday,

thank you very much for your great support.
I inserted the missing conductors according your drawing, please re-check it.
One land is not connected. I marked this aerea by an circle.

Hey Manfred I appreciate your work!

and I'm here to help. Any questions just ask. I'm going try to measure the resistors in a few hours and will post what I got.

the missing conductor was to R5 next to that. I miss that, was very close. sorry about that.

Don't be in such a hurry, there is time.
It's after midnight on our location, so I go to bed now.

Hi,

tried to recognize schematic -- seems to be a treble booster
with input buffer and some switching possibility between buffer
and treble booster (treble booster input capacitors, low pass
before treble booster).

2N4401 (npn as an emitter follower) does not really make sense
in this circuit, are you shure?

Gutshots are not really good, some parts of circuit board
are hidden by wires -- see e.g. R2 on schematic trial.

Additionally, wiring (and labeling) of switches must be detected
by hand, not via photograph.

Greetings from germany -- Good night and good luck

NoN
