EC Apparatus 600 power supply

[DeathRex]

We got a EC600 power supply for electrophoresis off of ebay. 45 pounds, 0 to 4000 volts, 0 to 200 watts, 0 to 200ma. It mostly works, appears to be 1980s or so. Can't find a schematic or manual for it. Anyone have a manual?

Is this the model you have?

Nope, it's an older model without the -90 and analog meters. The ec600-90 has to be mostly power transformer. This one is 5 X 5.5 X 6.5, the ec600-90 is 300ma.
The one we have works, but it has to 'warm up'. Takes about 1 minute, any earlier and it shuts itself off. I'm thinking it has a capacitor or 2 bad. It has a stack of 11 450V 47uf Illinois Capacitors. Most of the caps in the ps are axial. It has 3 circuit boards without solder masks. And 37 - 16 and 8 pin ICs all in sockets.
