Thank you for your advises, PerAnders.
Here you are:
1) By German law the distance between two mains wires of different polarity or the distance from a mains wire to GND (f.e. PE ground)
must be bigger than 4 (!) mm. (The reason for this is f.e. corrosion.)
Did I remember this wrong?
2) You see the little dot on one primary winding of the on-board transformer?
This is where the winding starts, and I wanted to keep it.
3) I use 70µm thick copper traces normally, but of course I would solder a solid core on the big mains traces, after all is done.
4) You are right: the relays need not be fed with a regulated voltage, but the LM555 timer should be for stable operation.
5) The LM555 timer solution has been discussed in this forum, and the 4K7 was one of the results of this dicussion.
I will leave it there, PerAnders.
Best regards - Rudi_Ratlos

Thank you for your offer, PerAnders.
Your board looks very nice and professional indeed!
And I like very much, that you contribute your circuit to the fame of the DX Blame!
So, my DX Blame friends: if you are in need of a "Soft-Power-On" circuit: Go and ask PerAnders.

Rudi,
Please add 4 amp boards for me please.
Thanks,
RKH (Ryan)
PS Have my boards shipped from the previous batch? Cheers.

Sure! Count me in for:
- 4 boards. (Vertical mounting, if possible)
- 4 protection boards
-And I'll take the kit option if available too (for 4 boards)
Thanks!
BTW, it's "HotCoffee", not "HotChocolate"
And please, let the board be green. Green is the color of nature, and environment. It's like having a little carbon sink inside your amp. If you close your eyes and concentrate, you can even feel it produce chlorophyll.
And the sound is airier too, more fresh air.
Thanks Rudi
...i will be patient. No worries on this end. Your shipping has always been very reliable.
Thanks for all of your efforts!

Round 3 for DX Blame - the almighty version
This is the current status of your orders:
I have just started a quote for 30 PCBs, single-sided, the thickness of the PCBs being 2mm, copper weight being 70µm, the surface having
a tin immersion finish (I will do another quote for golden finish) with this layout (the transistors will be mounted vertically, without ALU-L- bracket):
I will be able to offer you this PCB for 10€ per piece.
I will set the deadline of the 3rd round to Saturday, 26th of March.
Then I will order.
In the meantime I will do some research on what I can offer you as a "Small Kit" and will tell you.
Best regards - Rudi_Ratlos

Rudi, it might be a good idea to put up a wiki page. By this you can have an accurate information center. If you want any help with this, send me a message. Click at the link at my sig for an example.
BTW: I have set up a wiki page for my soft start. At this very minute I'm not completely ready.

Rudi, if you want to follow Peranders advice, the be free to include
the designators in the silk screen if you understand this may be good...seems crowdy to me...but people has different ideas about, and i want to let you free to develop the board your style.
Thank you Peranders...you are clearly trying to help... a very valuable support you're giving to us.

Carlos

Carlos, check the picture a couple of posts above, not particularly crowdy. It's also easier to identify for instance R14. An another thing is when(not if) you change a part value. It's rather irritating to have the values printed when they are not valid. In the industry it's virtually non-existant to have values printed.
Oh!... this is a very long and old story i can tell only by direct mail
An audio message to you...if interested to know, then go to:
nanabrother@hotmail.com
A long fight to convince people to remove part numbers from the board and to place the values..... there are reasons...people can see part numbers having an image with part numbers..so, they can refer to part numbers when needing.
I do think, people needs, to assemble, the values printed in the board, as silk screen, that will be covered by the component itself after building..so..board clean of too much informations... things we need just once when we build and never more.
Needing details of 6 years struggle...come to my email.

Carlos

Why has the polarity of the winding any importance here (although you already have changed it)?
