Sorry - something is wrong when importing your .xls BOM into google drive and that internal spreadsheet.... Som hickups here regarding parts..
Will examine the file shortly
@Harrison,
1. Thank you very much for the recent mails and I am pleased that my boards are 'en route' to Scotland.
2. Same problem as above:
I cannot download the BoM on my Mac. All .pdf opening software comes up with 'damaged file' messages! Any ideas?
[It opens direct from your site, but again, will not save or print.]
Many thanks,
Brian

I have no problem with the pdf's.. Will try on my mac in some minutes.
However if someone has missed this excellent thread.

Alot of useful tips and tricks there.

WOW! That was fast!!
My boards arrived, they look great. I guess this will be on the bench before long, will start working on the BOM and see what I need.
Thanks!
Great ! Looking forward to your review on the SYMEF thread. Thank you too.
Thank you. Looking forward Brian.@Harrison,

If the problem persists on the Mac let me know.2. Same problem as above:

Thanks Bambadoo, Let me know what else works and doesn't work on the site
kind regards,
Harrison.
It is a pity that I have not discovered this thread earlier. I was ver pleased with the listening results of my first build of the SYMEF amplifier, and I would be very happy to built a second one, but I see I am to late to have a set of PCB v. II
Harrison, I will wait for your next project that you told us in your last post in the SYMEF thread.
I stll have not finish my 1DIFFQC project, due to a stupid failure I did. A couple of TIP 142 went to "heaven". Repairing was set on hold because of a "house project" (painting) before Christmas.
For the time I am finishing my variotrafo project. As soon as I am throuh with this, I will give 1DIFFQC a new try. I hope to come back with a short listening test to 1DIFFQC compared to SYMEF.

Looking forward Liliya,
Thanks again, Harrison.
Sorry for the fuss......I am running Fiefox19.0.2 - a beta test browser - and have now had similar problems with their new .pdf viewer. Save a .pdf and it gives a message saying "damaged file". [I'd just managed to get them to print when the ink ran out ... totally forgot to reorder - so it will be a few days before I receive some. Our local town is a one horse town and that died last year!.....beautiful countryside though.]
TYPE 2
1. Place unpopulated PCB on heat-sink.
2. Use ink to mark the lead positions on the heat-sink.
3. Place transistors on heat sink with the pins bent straight up
4. Align the transistors leads with the ink marks
5. Use ink to mark the mounting holes of each transistor
6. Drill mounting holes
7. Mount transistors
8. Populate PCB
9. Place PCB over transistors
10. solder the transistors
thank you for the explanation.
IMHO, this is not a practical way.
