The 833A tube really only gets used in some ridiculous tube amps that have a huge number of compromises as Tjj226 mentioned. Here is one of those ridiculous beasts: https://www.stereophile.com/tubepoweramps/704wavac/index.html

Personally I would prefer buying a house for the price of that amp!

Buy the amp. This amp won't be around for long. No problem finding a fridge. Get a used fridge for cheap for now?

If yall are impressed by a 833a amp, god only knows what you are gonna say about a GM100 amp.

Not sure if this is it because it says transmitting triode 17V 18A. If it is a triode, maybe you would need four?

The Otello amp. Maybe made of gold since it is 600.000.00 in some kind of currency.

This is the most you can spend on a tube amp on an eBay budget - $120.000.00 for the pair:

Well @Xcalibur255 , I bought more 45 tubes, sort of by accident

I threw a minimum bid at this auction thinking I likely wouldn't win. Well I did, so I have five more NOS 45s. They are labeled Tung-Sol but I suspect they are rebrands...Sylvania perhaps? Haven't done the leg work to find out what make yet since I am at work. $30 a tube though seemed pretty good to me, hopefully a good buy. I’m all done until this amp is built. Needed some extras in case one craps out on me.

Edit: I am now quite certain they are Sylvanias given the top mica and plate construction.

Curious what a pair of these amps cost - forget it; I couldn’t lift two 100lb amps.....

The are the biggest DHT power amps (claimed as per the below review)

Cost wise I even didn't bother to look..... for obvious reasons.... hee hee. I am happy with my Rega Brio so far.....

You're right, all 5 are Sylvania made. It's good they all match, lots of sellers will mix brands in lots like these.

They look like late production, probably in the neighborhood of 1950.

Don't think I can lift 100lbs any more....When I go to Costco to get a 6 gallon box of water (pre C-19 days - they are all sold out of water now) I couldn't lift that box any more, and I have to open it and take out each gallon bottle individually. Getting old is not for sissies.....
