Hi guys for now PCBs are all out other than my private collection please don't pay-pal 😉 . OPB will be next 😀
Nothing left for me? 😡 Well, maybe theres another batch but maybe not. Thats fine, not a big deal.
One question..
Are we talking type1 or type2?
Notice that C1 (100u) has become C8 (220u) in type2. According to schematics at http://harrisonaudiolabs.com/Amplifiers/amplifiers.htm
C8 is not in the BOM btw.
Sincerely

Sorry - something is wrong when importing your .xls BOM into google drive and that internal spreadsheet.... Som hickups here regarding parts..
Collecting both for Symef type2 and 1diffqc 🙂

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
