Hello out there ! I’m totally new to this , but thought I might get some help with a Delta DL40 lathe (model 46401). Finally retired and ready to use it. The power controller (old Delta part #434-07-131-0002) is blown and I’m told it’s not repairable without being able to identify the blown parts. Would anyone have access to the schematics for this power controller ? The new owners of Delta (Black and Decker?) destroyed some of the obsolete parts and wiring information, I was told , when they assumed ownership, so the company can’t help me. I’d certainly be willing to pay for any information because the beautiful lathe is inoperable- hardly ever used, actually, without the circuitry. If anyone has an actual schematic of this circuit board, could you/would you contact me ? Would you be willing to share a copy of it? The lathe is powered by a DC 90V motor, PM wound, 1 1/4 HP. Also- any thoughts on how to get it working again if I can’t find the circuit board diagram ? Thanks in advance for any help. Rhodyjeffrey

If you can’t find a repair shop to look at it, you could try finding a replacement… Your best bet would be to try and find one on the bay… but I imagine they only show up once every third blue moon :)

Here is another member trying to fix a bad board: Delta DL40 Speed Control Board Fuse

Alternatively, since it has a permanent magnet DC motor, you could control it with a treadmill speed controller like the MC-60 or MC-80. Find a free treadmill and you can get everything you would need.
