Sorry, i try to translate in english.. and sorry for my orrible english!!

to aleopeldd:
i saw that you use a +-35v instead of +-70v. have you done some modification's on the original anthony's schema?
i have some problem with my av400.. i use the schema shows below, with a +-56v power supply.

the transistors q6 q7 q8 q9 e q5 are quiet hot, but the real problem is that i haven't no voltage across the source's resistors.
the voltages across R2 R3 R7 R25 R29 are slightly lower of the voltages writes on the pre-flight test in the holton's document.
someone could help me??
thanks a lot
