ups! misleading. my mistake, sorry. right voltage in this list.

You will get small expirience in SMD soldering too. It will be useful for you if you are a beginner (small bonus). There are a places at bottom side for SMD resistors and capacitors, I added especially them as a filtering-blocking in power supply lines to ICs.

A type of the capacitors is tantal 7343 or 7343H, value is 47 or 100 uF (the more the better), 10 or 16 V. A type of the resistors is 0805, 1206 or/and 1210.
You can find the caps in any oldie apparatus - motherboards, videocards, HDD boards, etc. Ie that you are able to find around - and set these.

Hi KT315.

Can you help me about your favorite Gold Mountain King Cobra? These days this machine was start to be my obsession. Unfortunately my Proteus can't see some of PCB portions at the picture of the King Cobra you allready post on a geotech. Please if you have some more pictures of this grate machine's PCB, send to me. Talking about CS5mx I decide to give up of this project due to the complicated calibration procedure. Anyway, thanks for your help about this. Once more, please help about King Cobra, I realy like this MD. This is your fault you know.. I have PCb layout file in Sprint Layout of Royal Sabre got from Vladimir Demchenko but I think that's a King Cobra is much more interesting machine and that I will can gain it like I was gained TGSL to detect a 1 euro coin at 40cm. One more question about King Cobra's schematic.. at the schematic drawn by W.L. there is 5 (five) Electrolitics but at the picture of the PCB I see 7 electrolitics!?!? I think maybe there are more disagreement between schematic and original PCB layout. Please help. I'll pay you a beer when we see ... Indeed, if you need any help, anytime but I can help you in any matter I'll do it gladly.

Thank you.

King regards,

Darko

hello Darko,

you can order PCBs right now from me. paypal accepted.

All the best

ok. have to draw...

Cobra

Can you provide parts list and pot pin out?speaker connection point etc?

[kt315]

Not cheap really, dear KT315, but main question is: if one of those PCB was populated and checked in real, on working abilities, and what results outcome?

the schematic is similar to any Tesoro, TGSL, TGS, you have a chance to check all declarations done before in another threads. nothing new. new is only a BOARD. it is a learning platform for all VLF like Hammerhead is the platform for PI.

1 board - 35USD and 8USD for shipping. sorry again for the some expensive price , must looking around another manufacturer.
