CS1200X 220V

Post by Upaleta » Mon Aug 02, 2021 9:51 am

Hi, I bought a used Peavey CS 1200x amplifier. It's the 110v ac one, my country has a 220v ac electric current. I know the amplifier can work at 220v, Im a technician and I would be glad if somebody told me the necessary settings to use it.
Thanks.

The best idea is to use a stepdown transformer and a stabilizer to get the voltage right, ALSO in some areas there is also the Frequency factor as line input capacitors are usually set up for a particular frequency range of power.
You need to match the input power voltage and the input frequency for the equipment you use.

Oh, the amp has two power transformers, and they have dual primaries, so a simple rewire from parallel to series on those primaries should do it.

Fuses for 220v would be of lower amperage.

Thanks, both of you for replying. To Enzo, that was what I was thinking but the fan works at 110V.

Ah, good eye. Schematic says two different fans, need a 220v fan for 220 and a 110v fan for 110v. I see the slow speed fan resistor changes also. Get the schematic and closely look for anything that specifies EXP or DOM. (Export or Domestic)

Thanks Enzo, I also saw that I have to get rid of C64.
Here its not easy to get a 110V fan. What would you think about connecting P20 with P37 and P38? That way I could use the original 110V.

Wait, you have 220 where you are, so wouldn't you want a 220v fan and not a 110v fan?

Are you looking for specifically 220v fans? Fans rated 240v or 230v are perfectly OK for this.
