Hi,
OMG
!! 150$ wow,Am very very glad that Am not in Germany 😀 !!
Last time when I got the Quasi Nmos Bipolor version PCB done,it costed me per PCB close to or less then 10$ 😎 !!
Perhaps if you finalise everything I can get some boards done here and can send it you !! how does that sound 😉??
Looking forward to the changes QSA !! But could you please shed some light on DC detect without relay ??
And ohh by the way please add my Mail ID to the List of Gerber wanted members !!
The ID is again : handsome1.blr@gmail.com
Regards.
but Im shocked, local german PCB Supplier want about 150 USD for 1 double side PCB without devices and Heatsinks.
OMG

A good idea to improve could be to add electronic turn on delay and DC Protect without relay in NMOS, have some sample schematics from American High Power PA amps

Hi Sounds Great
>Last time when I got the Quasi Nmos Bipolor version PCB done,it costed me per PCB close to or less then 10$
less then 10 $, how is it possibile ?

NMOS Amplifier PCB and Nmos Control PCB sample order cost about 250 USD compare to 200 EUR for 2 pcs. PCB to order by local supplier in Germany....
very good, I will pay your postage, if you can do it for me
> OMG !! 150$ wow,Am very very glad that Am not in Germany
Sorry it was not right 150 EUR compare to 180 USD
please give me 3 - 5 days, I will send Gerber files after finished

Thanks for the mail qsa,
I appreciate it
a couple of questions:
do you plan to use 130V rail with 6 x IRF460 devices ?
what power output will you be aiming for ?

Hi,
QSA its India anything is possible !!
Does that mean 200 Eur for 1 PCB of Amp and 1 Control PCB ??🙄
In any case please take your time and finalise the Design ! then once I get the Gerber will surely get it done ASAP and send it !
Although I have to check the postage charges for Germany ! Which service you prefer QSA ??
I'll check with various services and see which one will work out cheaper !!
What Happened to the Pic that I attached ?? what possibly could be wrong in posting that ?
Regards.

HI Quasi,
Its really good to see you here.
Can you help me telling one thing: I have a transformer that has two Primaries one 43 0 43 and the other is 17 0 17 can I join them to get 60VAC ? Thanks in advance!

secondaries in series
two conditions.
1.) They should be limited to the lower current of the pair.
2.) Only if one or both are dual secondary.

Reputed companies often have a fixed $50 charge for the set up charges. I've checked with some of them around Bangalore.
The small ones that do one off boards often hand drill it and I have got holes slightly mislocated and sometimes with wrong drill sizes. Sometimes track edges are slightly uneven. They charge much less than the bigger companies. But we get only what we pay for. Never risked making PTH boards from them.
Be careful about postage. Check with your local post office or even their web site. ( www.indiapost.gov.in ) I recently bought a book for less than US$5/- . It cost me about US$16/- to post it by registered airmail !
Cheers.

Quasi , thank you very much for the nmos 200 design.
I have built one and the sound is something to brag about(effortless and clear, exactly what i was looking for).
Excelent design.
I have attached a picture of the build.
Any suggestions(regarding the components or anything else) ?

Hi,
Ashok Am not sure which company you checked in Bangalore 🙄 !!
But I will not agree with what you have said
!!
Offcourse they may be small,but does not mean that they are crappy !
The one I got my broads is a small scale industry as well in MSR Nagar (if you happen to know Parts of Bangalore ), its 100% computerised and the output broad quality is here for everyone to see !!
Its just about knowing you sources well 😉 !!
So I request you to kindly rethink on this 😀 !
On the postage front,what you say is correct !! first of their charges will be a bomb and secondly they are very very choosy bout what they accept for overseas !! I checked with the local post office and immediately refused even talk further when I said its PCB and electronics related Item !!
I checked with FedEx they've quoted 2k INR or about 40$ !!
Regards.
