Amp companies that have gone out of business

[rhythmrocker]

I was unaware that Faustine went under. Please list what amp/amp-related companies that you know of that have gone actually gone under. Please leave out negative and bashing commentary - just the names folks, that's all this OP wants. If this thread gets nasty, I'll yank it for sure and certainly support the mods doing so. Before you post, please do some research and see what you can find out. Let's not list companies that are "out of business" if we are not sure as that would hurt those companies. Here's one useful webiste for more information: http://www.jedistar.com/jedistar%20amp%20dating.htm

FWIW, Jim Kelley amps are making a comeback with a partnership with John Suhr/JST Technologies. It's sure to be a winning comination.

Maven Peal is up and running -it says copyright 2010-12.
Amps are listed too.
I think that for some time they weren't offering amps.

Standell
Kittyhawk
Quidley
PRS
Blankenship
Bedrock

For the record, both Supro and PRS have been listed, but Bruce Zinky owns the rights to the Supro name (yes, the original company is gone, but there are amps coming out under that brand), and PRS has relaunched its line.

The clarification might be useful for some people.

Think Standel is still in business.
Quidley. Did a Swart/Quidley amp seminar out here in Mexico Norteno and Ed Quidley was kind enough to fly out for it. Too bad they didn't take off.

I think Standel also falls in this category....

Vanous

[skizziks1]

I could be wrong, but I believe AIMS was absorbed by Randall. I purchased a new one in '74 that had a Randall sticker on the top. Regards Skizziks
