I have made this schematic with a technic who doesn´t have experience with tubes amps. Someone can take a look and say if it is all right or not?
I have a Fender Hot Rod Deluxe 8 ohms and 40watts.

The schematic is there:

The values here:

R1: 8,2 Ohms / 60 Watts
R2: 22 Ohms / 3 Watts
R3: 33 Ohms / 3 Watts
R4: 2k Ohms /1 or 2 Watts
L1: 0,5 mH / 0,5 A
L2: 25 mH / 0,5 A
C1: 470 uF / 50 V
C2: 470 uF / 50 V
P : 200 Ohms / 1 or 2 Watts

Thank you!

On the quick look everything is fine - it`s a speaker impedance "emulator", known from RDH, and various "dummy load boxes" with similar parts values.
