Industrial SMD Gainclone - group buy

[troystg]

Hey Peranders-

Holy crap! I knew you were respected and famous on this forum but I had no idea you were THAT active and famous globally.

Yes your site came up on the first page of Google, along with many more pages of references to or about you.

Please excuse my ignorance.

As a side note, I did a google search on my self... The result was:

"Uh... Who?" :-)


Thanks again,

Troy

I don't know what makes me so popular for search engines. I come in second place if I use "TPA6120" and Texas is first. Sometimes I even come before the big elephants!

Can anyone explain why I am so popular for search engines?

Just a thought: if you reduce the space for the big power cap's and loose the option of the choice in diodes you can make the final version of the PCB even smaller. Don't quite understand the purpose of the MUR3020 diode in the current setup.

I have the option for the diodes just for flexibility and the space between them is for cooling. It's possible to attach the diodes on a metal bar, just in case somebody want to use this pcb in a heavy duty application.

Hi P-A

The pcb's found there way to me today. They sure look good.
The only drawback was that, by looking to the boards I realized again how small that smd crap really is.
Now I have to wait until all the stuff from Digi-Key arrives.
Tomorrow I'm going to order the trafo's and parallel cap's for the diodes, that will only take one or two days to have them.
Keep you posted.

Cheers

Glad you like it so far. It took two or three days to reach you.

Do you think the SMD parts are small? I have chosen "big" parts. Have you seen 0201 parts live?

If you can borrow two soldering irons, it will help a lot. Put tin on both pads. Place the part with a tweezer, then warm both sides at the same time and move the tips along the board fast. The part will suck into place while the tin is melt.

Start with the lowest (smallest) parts first!

Euuhhh, overhere in Belgium we only have "two" hands?

You will only need two hands The part is on the pads (you put it there) and you put both soldering iron tips on each side and at the same time on the pads. Everything melts and the part sucks into place due to the strong surface forces. You can also solder on pad at the time but this goes much faster and you don't need any precision, the part is doing that for you, by itself!

Well, I will sure give that method a try. One is never to old to learn.

Hi P-A

This morning I found an envelope in my mailbox which looked very familiar to the last one I received from you. When I opened it I was pleasantly surprised to find two nice little coils. Saves me the trouble of winding them myself, thanks. Today I also ordered five heatsinks which wil be used to make the housing for the amp's. Now it's time to contact my buddy the carpenter for some chunky wooden bases?!

Cheers

I'm glad you likle them! It's hard to wind these if you've got the wire and something wind on, Philips screwdriver in my case.

Now only a few parts are left. I'm very near to put power on.
