What is the function of the other PCB that sits above the power supply board? Can you show me?

Have a few problem in circuit.

1. I drew the wrong and that you was copy the wrong to your circuit (see picture)

2. MPSA42/92 not be used with +/-75V in the Vas .

3. Current of Vas the same as your circuit is (2.4/257.5)/2 = 4.66mA not 6mA you wrote in circuit.

No wrong, and no copy of you!

I practiced many times, to have the same value!
Schematic you gave false and not true reality!

The values ​​given are based on my practice many times, finishing last, but maybe it is just the beginning of the capacity.

I said I drew the wrong, if you draw like me, you also wrong!

Right the same as normal, but wrong the same as is sure to copy.
In here,many people have good knowledge,they will see now.

You have no knowledge of electronics so your practice does not mean.

If you have knowledge of electronics,you did not draw like that(you say your circuit is right).

Please see the image, line I is fixed. I = I1 + I2, I1 I2 increases, the reduction should decrease the VCE.
VCE Q29 is inversely proportional to I2 so P = I2.75 = 4.66x75 = 349mW <625mW.

What do you think it??
