    I do recall Rob (stanwax) running the 265 (and a 168 tube) off a 230V SINGLE phase supply. I don't know how he pulled it off, though, it seemed to require some extensive modding of his 265.

    Thanks for the schematics, anyway. I might need to recheck the start boost circuit in the future, the doubling voltage seems to be a little low. However, the tube starts fine.

    I've also discovered the probable cause of our tripping interlock: We might try running the 168 with the COVER on next time! *facepalms* DOH!

    @dsli_jon: I'm afraid I'll have to pass on the spare 265 offer. Shipping to here is going to be pain in the neck, and right now, I don't have the money for it. As you said, stripping one for two $3 keyswitches isn't really worth the effort.
