Magnum on steroids!

Say something about balancing the coil.
I did DD27 balanced to 100mV.
When switch to 18khz jumps to 900mV.
In original GM4 U1 is a TL074?

GB pot. is connected to pin 6 Lm324. should go to pin7.

Yes you are right, according to schematic it is mistake, made by me.
Funny thing is that i made few detectors on such pcb's and those worked just fine!??
I hadn't any problem to adjust GEB or Disc!?
I remember only that audio was slightly weaker than on original, everything else was quite alright.
Very confusing?
I will have to compare it again with original...

corrected .

[Toros]

You are fully right!

What is the problem? See where it goes blue path / level C1 / and does it link with C2 level near 10k resistor. Levels C1 and C2 are connected in two places along the path of GB Pot

Error ? Mag redu pcb.
BG should go to pin7

I built TH version. Depth is great. Depth in the ground is very good.
disc. 0 iron is removed,this is correct??

No i don't have it. I haven't made it.
I did only skim component placement as sort of reminded, in case i get any of those on service.
I decided not to trace out pcb draw from model 5 nor to trace schematic because it has 2 programmed chips which we can not reproduce.
The rest of circuitry is more/less ancestor from previous models with slight changes.
But now thanks to ozzy_sv we have more complete details on model 5 too.
Honestly... i had model 5 for several days on testing and didn't like it much.
From whole series i liked most model 4WD.

Man!
Ivkonic gave us schemes and PCB for granted, and you want to take further and numbered items specially for you.
If that is so necessary - take it himself and then post it here for our convenience.

chill out.
I respect what Ivconic did.
Read again what I have posted. I've asked if someone has already posted it, because it seems logical. I can do it myself, no problem.

Is there a lay file for SMD board with numbered elements in this thread?
There is one with types/values. I guess the best option is numbered elements without values (so sneaky chinese don't copy it)

Great job!

There are some inaccuracies, but I'm tired of it ((
