Eva is not contributing to the project, she can't because this is her common sense, she can't be useful to us because she is acting like kids and wants to fight, this is her common sense. I feel, if she reads her trifle post again, she will feel that she is useless.

Hope she deviates some day, heals quickly, deviates off her invalid behavior that she calls common sense and contributes to our project with something useful to the community...

I don't think you want to fight with all of us, trust me, you don't want to. Just go away, you are infected by invalid behavior, and will spoil things over board...

Homemodder,

I used standard-boards, but before I began to solder I covered the top-side
with some sort of adhesive foil, 23µm thick, named "ORASTICK".

And then: I took a very fine needle and drilled through each hole.

No secret at all.

But the girls are a secret and I won't tell anybody how I did this! 😀

Best regards - Rudi_Ratlos

An externally hosted image should be here but it was not working when we last tested it.

Thanks, interesting, ill google orastick. My amps go mostly into the boot of cars and the buyers want to see the insides of the amps like some american brands, the colours are catchy to the eyes and they love showing off their gear that they say looks more sophisticated this way to admirers. The work involved in doing this is for me as much as much as building the amp.🙁

Which girls, where??? My girlfriend isnt home yet so I can look......... without being harassed 😀😀:😀

I also like the suggestion to put more on the same pcb.

When you add more things to a board you have to be more concerned about how easily it can be debugged so I suggest you add some test points where you can place measurement probes without danger of causing shorts. On the silk screen you can label the test points "50mV here" or whatever it should be. This can help beginers. Also, I suggest you put the rail fuses between the power rail and the output devices only, with a direct feed to the front end of the amplifier. This allows you to operate without the fuses installed so that you can power up the front end of the circuit for debugging and setting up.

I need to make a new pcb for my TGM amplifier (similar to DX, a cousin you could say) but I also don't like the interface for Eagle - I tried it once.

Thank you, Bigun, for your reply.

So: we are on the right way.

The problem - at least here in Germany - is: unless you do not have a design implemented with EAGLE, TARGET or SPRINT,
you will never get your PCB etched professionally, i.e.: with silk-screen, holes drilled with correct diameter, ...

Call it TGM Dx style amplifier, then Omar will make it for you.

Seems to me, Omar (Metal) will become the Dx Layout Department responsable.

Your amplifier is Dx Style, so, Bigun Dx Style amp or something alike.

Keep the design with you, as creator, and make a joint venture...a joint adventure.

You know... i have always appreciated you..you are welcome to the Dx Corporation if you want.

Hugh Dean also like you... decent man.

ahahahahaha for the joint adventure!... beeing Dx style, then enters the big Dx family of awsome amplifiers

Your amplifier, MJL21194 amplifier and several others, despite created by yourselves, have a lot in common, the sonic style, the good performance we all have in our units..so..they are all cousins...belongs to the same family of awsome amplifiers.

We gonna invade the world Bigun....just a matter of time... even a pen drive will have Dx written on it..will be alike Coca Cola!

And i am studying hard SMPS....i have entered a forum with my Army, a lot of Brazilians..we are there saying..we want to learn SMPS!... moderators are personal and close friends, the owner is very close too... if someone bothers us..will disappear, vanish, instantaneously...there, or be kind or will not exist there anymore!

Brazilian Army is my group of Orkut friends (20 guys) that usually goes to the foruns i am.

There we have a huge power tool, "antimagnetidiotic".... these guys jumps out alike parts of metal in a metal separator machine for recicling purposes.

Yessssssss!

MAX just gave me an inspiration:

Perhaps is it possible to insert a predetermined breaking point (line) on the PCB to break off the PSU-parts if someone doesn't like them
(because he has already a PSU of his own).

I will talk about this option with METAL.

Thank you, MAX.

The source of inspirations is growing.

Sure DX, I meant to bridge 100 ohm resistor when circuit is ok -ok? not bridge mode amplifier connections - please, no. BTW I have my DX-scope and I am watching.....

Rudi, this is easy with paper/phenolic boards. It works well as you see in all the Wall-mart amplifiers. In glassfibre/epoxy boards, it doesn't give so good results. Mass- produced ones are made with long, narrow slots instead. These are expensive to punch. A printed line would be cheaper and you use a fine hacksaw. It kills the small saw but blades are cheap.
