I'm about to try to sell my Mesa D-180. Love the amp. Just don't need such a beast anymore. Can't find an easy specs reference anywhere. Any help is appreciated.
There is not even a complete schematic for this amp, so I would be really surprised to find specs. There is a hand drawn schematic for the preamp, an OM, and a page that describes how to reconfigure the Power Supply for different line voltages. No one seems to be able to find schematics for the power amp, power supply, or graphic EQ. There are also various images of magazine articles. IMHO most would call it a 200W amp. AFAIK they make a little more the 200W with 6550s and a little less than 200W with 6L6GC. Here's a decent reference: Mesa D-180 vs Mesa 400+
I have very limited documentation on the D-180. It was a short lived model, looks like there were only 681 built over ~3 years.
