I dealt with them a few years ago while I was building a SE tube audio amp for a school project.
Good folks to deal with.....
They actually phoned me long distance the next day after placing my order to tell me they could not give me a matched pair on the tubes. I was impressed by that.
I knew they sold speakers and tubes for amps but didn't realize they sold guitar/bass parts.....must be something recent.
Good Luck...hope this helps some
