Service manual or schematic for EV CPS2T

[Bob W.]

Last time I asked for a Line 6 schematic and ended up with exactly what I wanted. Going to try, this time, for an EV amp model CPS2T service manual or at least a schematic. The amp came to me with all the big filter caps blown and 1 channel out. I have it working but still something wrong. I need to see how to bias the amp and would like to look at a schematic of it too. Thanks for any help, Bob

electrotanya.com has them, search for cps2

here they are in any case

from the service manual
4.1. IDLING CURRENT ADJUSTMENT
Connect the DC-volt meter at the BIAS measuring points (see service connector) and adjust the idling current
via the trim potentiometer VR101/VR301 (on the main PCB printed board assembly). Adjust both channels of
the power amplifier A&B to a value of U(DC) = 7.5 mV. Adjusting the idling current has to be performed at
normal room temperature. In case the power amplifier was previously in operation, it needs several hours for
cooling off.
4.2. VCA - OFFSET
Rhythmically open and short-circuit the CNS2.1 and CNS2.2 on the main PCB printed board assembly for
channel A; respectively CNS2.3 and CNS2.2 for channel B. Use VR100 respectively VR300 for adjusting the
power amplifier outputs to their minimum offset (with oscilloscope to minimal peak value or to the audible
minimal volume of the interfering pulse).

Moz, you keep posting 'blanks'.
If the file was previously uploaded, before the Crash, you MUST change the file size.

Thanks a lot for the schemo and the adjustment info. I'll give it a shot today and see what I can do with it. Bob
