TM 808 White's

Thanks Leto I ment just the same picture you posted here. You are right for that its not 'a must' but the error check will be easier with the component placement picture you've just posted.

oops

Noticed that resolution of above picture really sucks on magnification.. sorry.
Here's better one.

Capacitors marked letters "ST"

Hi friends,
As I see some capacitors on scheme are marked letters "ST".
Are they polystyrene capacitors,called in Europe "styroflex" or "styrol" ?

hello Archi,
enjoy this info on the capacitors' marking american standart (I believe it is).

ST capacitors

Hi kt315,
Thank's for helpful information.It is very important becouse it means that in this places must be employed capacitors should own simillar features as polystyrene capacitors, which they are not produced praesently,as far as I know.I think first of all should be stable temperature.Is possible it to employ ceramic capacitors here,for instance based on X7R as dielectric?

Regards,
Archi

sorry ivconic for some delay. yes, you do the real your Home Work. great and hard work. my greetings to you! but I must note on some moments here and now... because in real I did not nothing on the subject

1. the schematic of TM-808. was done by Demon (remember this name plz). he cleaned blur copy and got very clear picture.

2. SMD version. was done by Vel. he wrote it worked just fine! but he changed off only PCB, did not repeat coils. he has access to brand TM-808. he only did put this PCB in SMD and got the result. he did the layout in Protel DXP.

3. coils' construction is very important if we want to wise up the schematic. TM-808 is only full copy of one from all modes of 5900 DI PRO (or 6000 DI PRO). it only repeats one static mode. these tiny PCB's in the coils must do some phase difference/offset similar to as it done in ordinary planar coil of 5900-6000 (Classic's etc. also). David sent some photos on the PCB's to me, but these are on TM-800 and has very bad resoliution and blured so, we have nothing info on the phase , but it must be these descrided 40-100 grades, accordingly to the patent you must be well aware of.

truly yours

David, thanks lots again!

Thank a lot for posted photos KT315!

still here what I did say about - first blur copy and the schematic.

your faithful friend.

hello kt315 i nedd circuit schematics of dm, old discovery two antens, model tf600 treasurefinder is some tipe discovery electronics inc, have two knobs for ground null
please can you help in these cuestion
thanks for your attention

hello detectoman,

I believe TM600 and TM800 are braza-in-law. but sorry I have not the schematic. try open the box and put up the photo. may be it will be get up to a light by anybody... I hope. as these have one primogenitor.

'the water does not flow itself under a rock.' you may be in course of this indian rede.

all best wishes and kindest regards

connecting in «DISCOVERY» TF-900 Automatic is MORE EFFECTIVE!
