Sounds EXCELLENT. Clean and clear with very powerful bass! Like a 300B with twin superchargers! Two stage design with Russian 6E5P driving the 833C DHT.
The filament alone is 100W (10A, 10V). Plate voltage on the 833 is 2300VDC. Total of 425W dissipation in the 833.

Cool, very cool! I'm surprised you don't get a lot of hummmmmmmmmmmm with the 10V filament.
How many watts output have you measured???
Boy, that high voltage on the plate really scares me, though!

No Hum. Filaments are DC, using an LCLC supply feeding two of Rod Coleman's DHT filament regulators in parallel (CCS and gyrator combination).
Haven't measured the power yet, but LTSpice simulations show 197W at 2.5V input.
I have a pyrex cylinder that fits over the 833 to protect us all from the high voltage, but I don't put it on while adjusting/tweaking on the bench. Picture below:

There is a 3" fan (31 CFM Noctua - whisper quiet!) under the 833 tube which draws warm air out of the chassis and blows it up around the 833 to cool the tube. The chassis is fairly well sealed, with two 3" filtered air intakes in the back to let cool, clean air in. So far it seems to work; in a three hour test run the chassis temp reached a max of 59C and the tube didn't melt, but I'm continually checking things with an IR thermometer to make sure.
PS: I also built a circuit to detect a fan failure using the fan tachometer output. When the tach reading falls too low (signaling a fan failure) the circuit sends a 12VDC signal to a SPST NC relay which then cuts off the 833 B+. A little bit of extra protection, at least...
The OPT is a 12K:4 unit, and the output impedance should be ~1.5ohm with zero negative feedback. I'm going to try it as is on my Infinity RSIIb speakers (4 ohm nominal), and see how it sounds. If it need better damping, I can add up to 4dB of local negative feedback to the circuit which should get me down to about 1ohm or so. Or, since the amps have quite a bit of power I could also invest in a pair of Speltz Zero autoformers to make the speakers look like an 8 ohm load - or maybe I can talk Dave Slagle into making me something better....
are those tesla rings on top of the tubes
Wow. Good looking build. Would love to hear it someday :thumb:
Quote from: topround on January 11, 2014, 10:46:02 AM

Those are heat-dissipating top caps, machined from aluminum billet. They help to cool off the anode and grid connections - the failure points for these tubes are the seals around the grid and anode caps, so they must be kept cool (relatively speaking!) or the tube will implode.
another good reason for a Plexiglas shield. protects you from potential explosions. I don't think I would trust these to run without being in the room at the same time.
oh and keep the cat locked up.
This pretty much sums my feeling upon 1st sight.

Very very nice job all around. I like what you did with the fan especially and how you kept it quiet. The face plate is pretty funny too.
Will each monoblock be plugged into its own dedicated power line?

No, one dedicated line can handle both.
Each draws about 5A, 120V at idle.

Not very portable at approximately 170lbs each...one output transformer alone weighs 62 lbs! Add in four power transformers, 6 chokes, lots of big caps, etc. per monoblock and it gets a bit unwieldy.
When I complete the second one I'll throw a rave - it's only right down the road for you, in Branchburg.
Wow! Gorgeous!
I hope I'm back up north for that rave!
The only thing that bothers me is that the two Hammond power transformers on top aren't quite up to the finish level of the other parts, so I'll be getting a cover made for them to match the output transformer and choke, eventually. But first, I need to build the other one!
You could always get monolith chokes !

Will you need one of these to put them in place? ;)

Those commercial guys all go for low voltage (under 1kV), high current, positive bias, pure class A2 operation, probably for liability reasons. That's not where these tubes like to be...they like multi-kilovolt, lower current operation, where it's also easier to make a good SET gapped output transformer with decent primary inductance. My amps are class A1 up to 40 watts before they go into A2. Very punchy.

Actually, we have end tables to match the media center, and the tops are exactly 18" x 22", the same size as the amps...I was "encouraged" to make that happen, so to speak. The tables handled my 230lbs sitting on them with no issues, so it looks like they'll hold up...

Parts alone cost about $11k for the pair. Then add in about two-three months of my time. I'd price them at $70k per pair, and that's probably too cheap. Then of course I'd need about $10 million insurance to cover me against someone electrocuting themselves.

Wow. $11k in parts alone. I can't wait to see when the 2nd one is done. With your time and labor did that also include your own amplifier circuit design as well in addition to any trial and error on the build? The reason I ask is one time I bought some tubes off an audio enthusiast and he showed me some tube amps he built with primo parts and he told me the circuit design as an old classic. I was just curious if it was the same instance here.
Thanks again and keep us posted.

Definitely not an old design, of course there is very little truly NEW in tube audio. It's based on my own ideas as well as those of a few others in the DIY community.
As an example, it uses a shunt regulator in the cathode of the 833 output tube instead of a bypassed resistor - the regulator sets the tube bias voltage and also passes all the anode and grid current from the 833, without the need for a bypass cap. The amp is two stage direct-coupled, so it's really important to keep the bias voltage very stable; that's why I have the big current meter on the front - I want to know right away if the current goes out of out of whack, before the big tube melts down. So far it's been quite stable.
It also uses an unusual input/driver tube, the Russian 6E5P tetrode, wired as a triode, it really doesn't have an American analogue.
Well, monoblock #2 is complete and they are in my listening room. See Picture.
The sound is amazing. Zero global, zero local feedback SET driving big Infinities...impossible you say? They sound GREAT - crystalline highs, full mids, and thunderous bass. The bass is WAY better than what I get from my 500WPC class D monos, believe it or not.
I need to break them in and ensure reliability, then you guys can pop on over for a listen. Rave eventually, once it gets a bit warmer...

Look at it this way, it's the same voltage as your microwave oven, and you let your kids use that, right?
10X less voltage than a CRT TV set as well.
Kind of wimpy, actually... :mrgreen:
Any updates Max or any more pictures? I guess the lack of updates means things are ok and the music must sound divine in your system with these monoblocks in place?
I've just been doing a little fine tuning and tweaking; I changed a few minor things internally a couple weeks ago when my son was on spring break and could help me lift it, mostly around minimizing the leakage currents from the 4 power transformers in each amp and equalizing the chassis voltages for lowest ground loop noise...I've got it now so that there is just about zero noise in the speakers at idle with my ear against the drivers, without lifting any of the electrical grounds in the system or installing "loop breaker" circuits.
Next I'm going to tweak the fan speed to get the lowest fan noise possible while still maintaining adequate cooling. It's barely perceptible now, but I'm a perfectionist. I also want to slip some neoprene under the big high voltage power transformer mounts to eliminate a slight buzzing they make on occasion.
Unfortunately one of the Pyrex glass cylinders cracked on me - the supplier says that happens occassionally when stresses are set up in the glass from having holes drilled in it. He is replacing it for free and this time he will melt the mounting holes in the sides to eliminate the stresses. I should get that back in a week or two.
Meanwhile Pete is making me some 7+ American power cords for the beasts!
So, all is well and getting even better. Rave to come once I've got it tweaked to perfection.
Sounds great, wish I lived closer!
From what I remember about using a fan for cooling, you just need to have air moving in the right direction. It really doesn't need to be "blowing", so you can probably set that fan speed fairly low. Maybe even put a rheostat on it and make it adjustable.

Actually, I have a 6000V gas discharge tube inside the chassis across the OPT primary in case of an overvoltage situation. The lightning bolt will be across that tube instead of the OPT or the output tube.
Update: I had Pete make up a couple of TWL 7+ American Power cords for the amps and I received them on Friday. First impressions are that I have a lot more bass than with the generic 14 gauge molded cords I was using, so much so that I had to turn down the bass control on the EQ box for my RSIIb speakers, because the woofers were distorting from overload! Now that I have it tuned in at the low end things sound very clear and smooth; I presume I'll have some changes as they break in over time, but so far, so good.
PS: The 2500VAC power transformers had a buzz that was audible from a few feet away - that has diminished quite a bit with Pete's cords! I think a little damping material on the end bells and they'll be silent. An unexpected benefit!
Thanks, Pete!

Just suggest a date and time by PM and we'll set something up.
Only audiophile grade marshmallows allowed!
I'll be over, but probably in the fall... Can't stand the traffic on the Belt, SI Parking lot, Verrazano and the Jersey shore back-ups...
Been there, done that too many times... :duh
Enjoy the summer! :thumb:
