Powerful 1000 watt Tube amp video playing the organ of Notre Dame de Paris, Fun stuff !

This is impressive to say the least

Wow very cool, I'd like to see what the output transformer looks like.

 

[Harvestor]

I love the history of the tube amp and just tubes in general whether it's for broadcast reproduction or audio Etc just too cool here's a little video from 1940

I love to see what seems line voltage regulators glowing in tune with the amp's demand.
Very cool.

Those are the mercury vapor rectifier tubes. Six of them for the output B+, since it's a full-wave three-phase power supply.

The two in the front are for the smaller tubes (input and drivers)

What I dig about it, is that you can see the output tubes heat up, in the louder passages, due to increased plate current. The yellow spots on the tube plates get bigger and bigger. And it's ENTIRELY NORMAL for this to happen. That's just cool.

Regards,
Gordon.

While not nearly as entertaining to watch, a reviewer friend of mine had a pair of VTL Wotans driving his big Nolas back in '01. While rated about a kilowatt in tetrode, he ran them triode for only 600 watts. I fully appreciated his concept of "authority" hearing them. After that experience, I purchased a pair of little brothers with a third the power and number of tubes.

No cool mercury vapor types, just a couple dozen 6550Cs per amp.

A cool light show, heat for the winter, and music! Whats not to love?

If you want to recreate a bit of that soundstage at home, listen to a weekly public radio show called "Pipe Dreams" with Michael Barone. You can directly stream it here. Use your big speakers and/or a sub. You're going to need it.

Even better is to hear a pipe organ live. On Dec. 31st, a friend and I went to hear a free concert at the big Christian Science church in Boston. A large pipe organ with 13,500 pipes being played by a skilled organist is an amazing thing to hear. Check this listing for some events.

I confess that I'm not a major organ music fan but I enjoy some of it. For sheer power and awe, you can't beat it.

Very cool!

Wao, the output transformer are in oil. That's interesting.

Wao, the output transformer are in oil. That's interesting.

And necessary, given the voltages.

 

[damacman]

That’s cool as shit!!

 

[N8Nagel]

Want.

 

[soundmotor]

I'd like to see Filter Hey Man, Nice Shot run through that at the appropriate level.

 

[GordonW]

Here's somebody with TWO of them- playing stereo!

If you check out that poster's other videos- you can see videos of where he restores these amps...

Gordon.

I really enjoyed the video. Thank you for posting.

That video is like looking into the viewing ports of twin gas furnaces at full flame. Wow!

 

[FONSguy]

I had no idea! WOW!!!!

 

[Pio1980]

Fascinating approach. Haven't seen larger RF tubes used for commercial audio like this.
The power level puts the modern commercial switch mode amps into perspective.

You just know you're in the ''big'' leagues when the chassis requires flat bar,round bar,square tubing,gusseted joints and a welding machine
Removing the two lower bolts in the A-frames allows the unit to rotate for service.Nothing says high voltage like ceramic-post terminals....
