TM-800

[Geo]

Hi.
A friend gave me a TM800 who don't work properly at caves. I want to find a schematic so to repair-adjust it. There are two trimmers on the pcb but i don't know what they adjust. Also at cave mode who is the phase shift????
I wait for any Help!!!

Regards

Hi KT315
I had read all the threads ...., simple i said maybe any new member have something.
I know (as you know) that there are persons here that have the schematic. It is an old schematic, so where is the problem for the whites???
Yes you understood good, i mean Carl .

I must thanks you for the linked sites. I will put the TM800 to the shelf. Never mind, i have the gemini III.

My Regards

do not nurse an hope... Carl does not share out fabric schematics here. that is forbidden by copyright. all shematics on Whites had been got from third party, you know this fact as well!
draw own schematic. put all PHOTOS ALL INFO ON ANTENNA ALL YOU ARE ABLE TO PUT. if you do not wish to make it... your Home Work... so then you have not an moral right to ask the schematics from geotechers, from Carl, from Eric Foster, from Bob Sickler, from Terry, from John, from Andy, from Henry, from etc.

Geo, look at topic again, there are mostly schematics not photos (indeed of TM808 but probably not much difference).

Hi WM6.
TM800 has 7 IC's and TM808 has 13 IC's.
So there is big difference.

No my friend!!!
No reason to reverse a so old detector. It is better to let it at shelf.
Very simple, i wanted to experiment with the cave mode but it's big way to reverse the detector so to make the experiment.

an reason is to find the aptitude TM-800 vs 3900 di pro as it was with TM-808 and 5900 di pro. developed that TM-808 is only one mode and some part of 5900 di pro. specific mistery there was not of. draw my friend... draw...
