Monolithic Tube Power Supply Success!

Chris and I have been working on this power supply off and on for a year and a half. There is alot under the hood on this one. The previous power transformer failed but we had this beautiful Kenyon transfomer available. This power supply is stable and runs cool at 940v and 280ma.
 Of course the mercury vapors are 866A but the not so common tubes are the 6D22S which has a 30 second warm up.
 The blue glow is captivating and the westing house meters are stunning.

 I filmed our first startup here.

Now to build the other three chassis for this amplifier 8-)

United Electronics 966 966A

I assume this is the same as the 866A and 866. I'd love another pair of unshielded 866. The one I have is abit scary looking.

RCA 816 Mercury Vapor Rectifier Advert

The 816 is the Junior of the 866/866A.
Might need to procure a few of these as well.

Mercury Vapor Rectifier Tubes - RADIO 1934

A 1934 article on some early MV tubes.

It doesn't get anymore "I'm a mad scientist than this tube".
I need a power supply with these tubes. No logical reason really. It just doesn't get much more robot like than this... WOW. This guy must be really rare can't find any pics or datasheets on him.

Wild Mercury Vapor Tube Ident?

I found this pic a while back on the electroweb. For those that love the mercury vapor glow this must look so cool. Can someone identify this tube?  Does mercury glow count as bling?

Large Mercury Vapor Tubes In The Movies

I am being stalked by large mercury vapor tubes. I was watching the classic film the Evil Of Frankenstein when I noticed his lab had these familiar tubes. There were pulsing and looking cool in the lab.
I think some of the mercury got loose at some point. Definitely not a safe environment.
There were several shots were the camera perspective made the tubes look very large.

More Mercury Rectifiers Of Unusual Size

 Ok Jeffrey no offense but if you get some of those rolling I'm going to start visiting in a Space Suit ; )

1939 - BTH British Thomson Houston - Mercury Rectifiers

I wonder when we will see an amp featuring these rectifiers from EMIA.

1930's DeForest 569 Mercury Vapor Rectifier

I think this is more of a product announcement rather than an advertisement. The tube structure is very interesting. I'll have to keep a look out for the 569.

electronluv modern audio art

I am an stalker. The site has been vacant for a year or more. Last week I noticed a new site with links instead of a placeholder. It seems Josh has some new horns, a turntable, drivers, and many new goodies or at least audio porn. This is not for those of us light in the wallet. I don't see a problem charging large quantities of money for what electronluv creates because it some of the best art I have seen in years. For a tidy some of money you get fully functional sculptures which should go up in value over the years or at least that is my bet.

Go to and do some window shopping.
