Hello to everyone.

I am trying to build myself a copy of X250.8. I hope, that it is not a problem. I am using the old published schematics from the other projects, which Nelson Pass made free on the internet, together with the specifications of the X amplifiers and pictures of the amplifiers from the net. For the moment, I believe that I managed to reproduce, to some extent, the circuit. However, I cannot understand the following: in the attached picture it looks like the 8.2k 3W resistors are the feedback resistors, but I cannot understand why they are 3W? Also, should they not be with accuracy greater that 5%?

If any one have some ideas I will be happy if he shares them.

Best Regards,
