Hi KT315
are you have this files ?

i know this is an old thread now, but if anyone in the uk has a Whites TM 800
i have an instruction manual that they are welcome to have. i had a one some years back and it came with two manuals. so i give one with the machine and the other one just got put away in a draw.....

This is schematic for 3D. It is similar to the patent invention of TF900. Schematic sheet for 3D above schematic for TM800. !!!

Here is TM600

As far as I can tell, just the null pots are changed to trim pots (removed from user control). Possibly some resistor values changed.
I haven't gone through the board component by component, but everything I have compared so far to TM800 schematic is identical to TM600.

Not sure if TM800 uses 0-ohm resistors for jumper like TM600. They are not shown in schematic.

Thanks...

I put the posted schematic into DipTrace free version. So it took two boards double sided because of DT freeware limits. If you want my files, you can PM me your email and I will send m schematic and PCB files.
If you get DipTrace, you can verify my work and print PCB trace for making your own boards. You should be able to merge them for etchng PCB.
BTW, I only did the main board, not the antenna circuit boards because I am upgrading my TM600. I don't plan to go that deep into tearing it apart.

Who are the differences between TM800 and TM600???

Thanks KT315
I meant a PCB that can be done at home.
Apparently TM800 scheme is not as complex so I think an interesting project to build at home.
