I have one of these that has shat itself (two of the transistors in the PSU have exploded, erasing all markings [Q1 and Q5]). Anyone out there in interwebland got a schematic for the PSU ?
Cheers

Default CAT sl1

Hello there!
I am also looking for a schematic of the psu of an Convergent SL1, because I don't know if I got the output voltage right. I got the signature with the psu wich you can decouple fro the amplifier. Mr Stevens told me that the output voltage has to be round 370vdc, but there are also three other output connections with 2x 12 vdc and one 10.8 vdc. Is it possible that there is some rectification on the preamplifier board? When I look at some other diy sites, there it says that the psu output has to be around 260vdc, 370vdc looks a bit high to me, but I am not sure, and I dont want to distroy something. Thanks for any answer, Mojo Teake

Hi there,

I am also looking for a copy of the power supply schematic as I want to change voltage on my CAT SL1 to European standard. Did you have any success?

thanks,
