Hi!
I have an SSA400 amplifier that I turned on yesterday. The drive is a TD90, perfect for communication with the amplifier.
I put a 50ohm dummy load on the amplifier, a TD90 got a A1 press CW and checked the instrument at the front of the amplifier.
On the UD1, the trimmers that controlled the drive were unwound, I started to rewind nicely during transmission.
The problem is:
Each module brings its described values, except for UD2, perhaps moving two divisions on the scale.
The output power according to the instrument is only 25--30 on the 100 scale.
The amplifier is intact, not mounted, could not use much, where do I look for the fault?
Voltages are fine
