Tesoro Tejon

[kt315]

Have anyone build this Tejon? Itґs this PCB correct and works proper?

you may find PCB in RAR here http://www.md4u.ru/viewtopic.php?f=25&t=3056&start=250
vlaser makes...

@KT315 : I hope you'll appreciate this new design.

Tejon the best machine in Tesoro.

Must have!

Firebox, make anything simpler this is my suggestion to you. Tejon is based on u-chip, maybe PIC one. do you have access to HEX to program the PIC? not. CAN you write the code yourself? NOT. so why you need in the complicicated schematic??? there are massive of CLEAR analog VLF schematics you may begin from now!

Qiaozhi,

maybe on this board / thread ? http://www.md4u.ru/viewtopic.php?f=2...128364#p128364

It's the Russian back-engineered schematics that I looked at. The Tejon has a micro-controller inside, and it looks like someone has replaced the micro with analog electronics.

Good luck with that.
I looked at the back-engineered design a few months ago and it appears to be full of errors.

Hi all,

I am looking for all Tesoro Tejon Files for example PCB, Layout Files and Part List to build them! maybe in SMD too....
Does anyone build a good working Tejon ??? so i need this PCB Layout

Have someone this Tejon bulid? This PCB works/correct?

Thank you!

Pic is not need.Only lose VCO and variable tone.

Doesn't the Tejon contain a micro-controller?
If so, it's not shown in the schematic.

Yes, it does.
IMHO, It's used to generate audio and maybe to control a 4053 chip ...
Original design don't have no 4024.

The scheme is fundamentally correct. there may be some error in the values of some of the capacitors. I personally remove any parts of the scheme but I had no "C" meter to measure capacitors

Hello Ivconic,
It comes from yours and from N@SKO.
I've updated it with the differents replies of this thread.
I can't find more infos over Internet except from http://www.md4u.ru/ but it's about the same as here.
But I say, it's not my project, it's a Geotech's project.
The only thing I want to do, it's a working base. Anybody is free to experiment it and correct it.
Have a nice day,
Hugo

No i have nothing to do with schematic. I saw it first here too.
I wonder if it is accurate or not.

What is the source of schematic,where did you obtained it?
