Here's one I haven't seen before: Model 605 0-6VDC, 0-500mA. Looks like it has their custom oven like the 2005 models. The rear panel is like Swiss cheese.
Someone buy it so it stops tempting me.

Somehow I lost track of this thread, so I totally missed this! I picked one of these up on eBay about a year ago, but it's still sitting in a box awaiting restoration. Mine powers up, but the oven never goes off, so I think the thermostat is bad.
That's a very common problem with all these ovenized PD supplies and a big disadvantage to keeping the oven powered even when the supply is turned off: The thermostats use a bimetallic disc which wears out after a few hundred thousand cycles.
The thermostat module is actually soldered to the bottom of the oven's inner can (under the socket). It's of a size and shape that appears to no longer be made and I've been unable to locate a suitable replacement.
It's such a common problem, that I've actually designed a fairly simple, yet accurate oven controller as a replacement. It's 100% solid state and keeps the oven within 0.5C of the set point. Originally I intended to use a relay, but opted for a little Triac in a SOIC package instead (no sense replacing a mechanical switch with another mechanical switch).
I need to finish laying out the board, but once I do I'll have a batch made and do some final tests with my own supplies. If everything works out, I'll offer up retrofit kits if anyone is interested. It should be rather simple to swap over to my controller.
