RAJ sent me those boards last September

And now i am buiding it.... if i delay some more days, he may say... or may think that sent me "last year".

ahahahahahaha!

The boards he make are perfect..but has not silk screen...no problems, we pick a pen and we produce the informs we want to install parts.... then... we remove the paint with alcohol and ready!

This is the silk screen of no dumb people.

But also sent me a problem.... the DogcMK3, or other name, very complicated

to me... seems code from parts list.....well.... the amplifier is not simple..... have strange parts (to Brazil, South America, Third world, in development countries).... this LF411, operational amplifier chip.... this is complicated... i cannot use the boards...and they are exactly the ones i prefer...very small ones..nice ones.

I do not know what to do with them...... were to put the boards...were to trow the boards.... were to introduce the boards.(negative...ahahahaha..not there!).... i have not this part easy... it will more easy to find a grain of sand in my beach..that one that has blue colour with yellow strips and coiled tail.

Maybe this is so easy to find as Coca Cola in Bora's place...but here...hummmmmmm.... problem!!!

regards,

Carlos

Carlos my brother,

Everything is OK now!

It is possible to use LF356 / LF357 / TL071 / OP77 and many other OPAMP-s instead of LF411 in DOGC-MK3. Even 741 would probably do the job, thou, I don't recommend it if you have better options! At least TL071 should be available worldwide. LF411 just have best characteristics for that purpose (DC servo) and is a best overall compromise because it is cheep and widely available (at least in Europe). It is low-offset / low-drift type.

Don't throw away those boards... DOGC-MK3 is one really fine amp. You might be pleasantly surprised what it is capable of!

I think Raj made using Bora files.... do not know exactly if he made by himself

... i think he used some already made layout and produced the boards.

He is my main boards provider.... he can do those boards fast, with excelent quality and very special price.

Boards from him do not have Silk screen.... but i think he can be very helpfull for our forum if someone organize a group buy having RAJ as boards provider.

RAJ is a good friend too.

regards,

Carlos
 
I have to buy some parts .... next year that will start soon

And them will finish those Techno boards.

I will distribute copies of those boards to friends around the world...in january, all world continents will have, at least one man listening Bora design.

Bora is a very nice guy.... and produces nice amplifiers.

One of my best friends, those ones i talk daily is near you..from Croatia.... the guy is in our forum too.

regards,

Carlos

People is important to RAJ...he loves people.

He sent me many boards... a huge package, filled till the top...heavyweigth and cost a lot of money for him to send to brazil...he made free.... to see my smile.

This is what we want in our lives folks.... love dedicated one to the other...less selfish feelings.... less ME (mine) and more US (ours).

For the good of mankind... the answer is easy... we have to be free to love our brothers...no religion, no politics... love only.

regards,

Carlos
