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

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
Walter

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!

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!

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?!

Hi!
Now is all the SMD parts finished exept for the C1 and opamp (have not got them yet).
It became fairly easy and quite fun really after gaining some experience.
My hands are shaking quite a lot, and my eyes have been weaker by the years, but it still was manageable. It was important for me to have a good magnifyer glass with a lamp as a tool.
And two soldering irons of course.
I put on some DC power and could measure +11.83V and -12.09V after the regulators.

Well done! It took me approx. 2 hours to solder one board and it was rather easy. Now I'm ready to put voltage on it!
A detail of the board. Notice that I have cleaned it with alcohol. It becomes a bit more messy after soldering but I cleaned it just so it looks nicer in the picture.

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

Hi P-A
Nice solderwork. Also impressed with the quality of the picture. I'm realy curious about the sound quality. So far I haven't started because I'm still waiting for the parts to arive
, I hope it will be something for next week. Yesterday I paid my friend the carpenter a visit so I already could make me two walnut baseplates for the amps.
Cheers

Hey Peranders-
Awesome looking board. Really nice work.
When are you going to have assembled boards ready to sell?
Joking... But no way I'm going to burn my fingers trying to solder that small.
What is the “extra” male quick connects on the board for? 2 for AC input, but I counted 3-4 more on the board.
Again, GREAT looking work.
Thanks,
Troy
PS, For my idea of miniaturizing... See attached photo.

Camera, Minolta F100 4 Mpx, nothing special. Lighting (or lightning as a wrote somewhere elseGeWa said:
), 1300 watts halogen with an umbrella, plus reflex boards and white boards. The secret is the lighten in other words... and also a very stable tripod plus remote control to avoid vibrations.... Photoshop, "sharpen", "unsharp mask", "contrast", "brightness", "levels". Photoshop is wonderful.Thank you all for the nice words. The pcb feels really rigid, 200 grams with parts!
