Total PCB count is now up to 181 boards. This is a very good effort here by everyone.
Lets see if we can get 19 more boards to make it to 200.
Jan should be very pleased with this group buy for his very sound design.
For all concerned , check out his PSU design to go with it.

PSU voltage rails
Hi Jan, I'm almost sure that I read in an old assembly guide for the Lynx amplifier that it could take voltages up to ±70 VDC. Why is it changed to max ±60 VDC?
The reason for asking is that I have two transformers of 2x50VAC waiting for this project to start.

You have a good memory
And it can still do +/-70VDC but remember to lift the Power resistors 5mm from the PCB.....
Furthermore I had the opinion that this was not interesting driving it at such high Voltage exept if you have vey high impedaced speakers.
At 70V the SOA limit is 3A for the output devices, which gives a total of 12A for all four output devices...
But as said, you can use +/-70V

Jan,
Just took a quick look at your schematic. Don't you want the input signal to be applied to pin 3 (the non-inverting input) of the OPA627, with the negative feedback voltage divider tap of R120/R121 applied to pin 2-the inverting input?
...Jim
No
If I wanted that I had done that
Though the output would have been inverted......

Congratulations Jan, on reaching 200 boards in this group buy. Just watch out Paypal does not get on to you with a sudden huge influx of money into your Paypal account as they might think you are laundering money. Look at the post in the UGS PCB group buy from Vincent in France.
You might want to be prepared and have all your documentation saved for request for payment to all the buyers so you can show Paypal this is legitimate on your behalf.
Just letting you know in advance.
Best Regards
Gary..
