Hola Wilson,

Can you describe the problem with the CLS? I had an issues long time ago with them. I remember that there was not any DC for the RED color cable (bias voltage). First thing to check are the 15M ohm resistors (Brown, Green and Blue - five resistors) at the end of the ladder DC voltage. Also the transformer. The AC voltage is circa 200V to 260V at the secondary wound of the transformer. Swap the transformers to see if this is the culprit. The bias DC voltage is circa the 2000DCV. Be careful with your tester to check this voltage. You need a high voltage probe to measure this voltage too.

Another thing to check are the solder joints for the blue and black cables at the stat panels. Sometimes these joints are not doing a good contact. You need at least a 100 watts soldering iron to do the soldering.

Happy listening!

WOW, I just look the pic and that's one of the first CLS power supply. I only see two of these 15M ohms resistors. Anyhow, check the resistors for open.

Here is a trick for you, to check the high voltage. ML sent this to me.
Reminds me of when I was a kid and opened up my polaroid camera. I started poking around inside and got the crap zapped out of me! I told my dad later and he said it was probably the capacitor in there. Wow, was that strong! I thought I was safe because I had the batteries out of it.

Getting zapped with the CLS would be just a bit worse,lol.
