Does M&R provide schematics for their products? All my other machines came with them, and I would love one for our
Sprint dryer. I realized yesterday (after having this thing for 10 years) that there is a beefy 240/120 transformer that is powered on
24/7 (for the controls) that I would like to nix, it's just wasteful and will eventually die.

Thanks for the replies.  I'll have to dig in there and see if the old one has anything on it.   

Do you think it will tell me voltage in/out and watts?

maybe a schematic would tell you, or an M&R tech would tell you what the voltage plus AC/DC should be on each side of the transformer

Can you pull the old one and find the numbers on it?  It's probably half the price elsewhere.

They obscure/remove markings.

If you know the voltages in/out and watts you can easily find a replacement.

Not sure what it is about the MSP3140, but those things eat what are otherwise considered least likely to die components in
the electronics world, IE transformers and chokes. I vaguely recall someone adding more cooling fans to the controls box which
probably isn't a bad idear.

Got it, appreciate the input.  We have a bunch of huge skylights, it's like being outside in here, so we have to have a dark room, plus we would
need like a million cabinets to store screens so we had to build this one out. It's the long term storage/exposure that gets me, can be such
a hard thing to pinpoint, IE "maybe we could have gotten a little more detail out of that one". I guess I could image a high mesh screen and leave
it sitting for a couple weeks for testing.

Ya with sky lights you probably need to do it. Here we've left screens certainly for hours out, not normal thing but its happened. Without any noticeable affect.

We have LED Lights in our entire shop, high bay out in warehouse/print area and also normal LED in our offices. We coat/image/burn in direct light, no dark room here. We did mention to the light people the type of work we did and he did make a choice on light color but not sure what it is to be honest.

I just know we never have screen issues and I didn't want to mess around with a darkroom, our building doesn't really have a great spot for that.

We run just cheap LED tubes and put clear UV sleeves on them.

Has anyone had any luck finding an alternative vendor for the transformer that the MSP3140 uses.  M&R wants $623 for it.   I tried looking up the numbers shown on the photo but no luck.  Item #1019146

Do I just bite the bullet on this one?
