A question to the Forum members, who are well versed in putting together amps homebrew or commercially made amps. When looking at new tube amps for stereo systems I came across this pair of mono block amps. What do you think actual part cost is on these guys?

 These amps use a 833 triode and looks very good with the 833 in plain view so you can see the glow from the tube. Silver wire is used for all of the wiring in the amp which makes for a good selling point. I am not sure how much of a difference performance wise the silver is when compared to cooper wire, maybe some here on the Forum knows. These amps sold for over $300,000.00 for the pair. At 300K for the pair of amps, might just be time to get into the amp building business. They can power your $500,000.00 speakers that weigh 2800 lbs a piece.  Shocked

If anyone on here is shopping, I'd be happy to build them a pair for $290,000.00   Smiley

Poor timing (global recession) for entering that marketplace.  The market that does exist is largely Eastern Asia.  IF you check closely, you will find many closing or having trouble keeping the retail doors open.

For $300K you can hire a band to play for you in your living room for several hours a week for several years.

Without knowing the exact components used, I'd say the component cost is easily under a Kilobuck. You have to remember there isn't a helluva lot to a power amplifier in terms of parts count. Eyeballing the pic I see the nine pin Noval 1st audio tube mentioned in the text as a WE-437 (probably the Soviet 6S45P-E equivalent) with a couple of KT-88's driving the 833A. Nothing exotic there, the 833A was common in the modulator and PA sections of AM broadcast transmitters and the KT-88 was a popular Hi-Fi tube of the 50's & 60's. The custom machined aluminum chassis is worth a few dollars, but, c'mon........ This is hype for the sake of hype. The design uses a transformer phase inverter. Big Whoop, so do the four 60 Watt Dukane PA power heads I scored a few years back at a city auction.

BTW: 800 Watts in for 150 Watts out. Woof! That's Class-A on steroids.

Note to N6GND: For $300k you could get Barry Manilow playing your piano five nights a week for three years or better............ About a month ago he played a casino in Tulsa and the response was so underwhelming they advertised "tickets as low as $9.95" a couple of days prior to his arrival.

I think Mandy was the only one who showed up, and she sat in the back wearing wrap-around shades................  That's gotta' hurt!

Parts cost about $ 500, labor about $ 600 (made in Japan), $ 60 (made in China).
Before you buy visit your otologist and make sure your hearing is good enough.

I would rather pay you $300K and listen to you bitch and moan about tubes, than paying $300K to listen to Barry Manilow.

Come to think of it, I would have to be paid to listen Barry Manilow.

Yo, Vinnie Bagadonuts..........

Here's a brain teaser for you:   Download this schizmatic --- http://www.nostalgiaair.org/Resources/view.asp?FN=\M0012224.pdf

I know this is a six tube superhet and slightly above your pay scale, but here's the question:   'Spose you need a 35C5 audio output tube but you don't have one 'cuz you cleaned out the garage last month. You have plenty of 50C5's. I say there is a way to adapt the radio to a 50C5 with only one itty-bitty little jumper wire.

How does you did that?




You know I can't smile without you
I can't smile without you
I can't laugh and I can't sing
I'm finding it hard to do anything
You see I feel sad when you're sad
I feel glad when you're glad
If you only knew what Im going through
I just can't smile without you

 TNX for all of the great replies to the post.  Smiley Nice profit margin to say the least and I suppose the amps must sound great, but it would be very hard for me to pull the trigger and actually pay that amount for an amp. You can tell the XYL that you have a new interest in stereo equipment. Show her the price of those amps at 300K and you should have no problem getting your new FT-5000D radio. It will look like a bargin when compared to those mono block amps.  Grin

Are you sure those are dollar figures and not yen?

There is more BS in the high-end audio business than in any other marketplace except maybe for wight-loss or penny stocks.  I once worked building speakers for a man who is in the high-end audio hall of fame.  My statement was his opinion also.  Scientific testing of these claims couls easily be accomplished with the use of double-blind testing but you will NEVER see that done because it would systematically expose the frauds in the business.  We hams work with pretty accurate frequenty control and response into the gigahertz range.  Audio frequencies are pretty easy after that.  My favorite piece of H. E. audio BS are the black polished stones that are placed on the cabinets of audio equipment to "absorb broad-spectrum EMI".  A set of three units, each containing "tuned circuits requireing no electrical connection to the equipment" costs $595.00.  Phew, I wish I had though of that first!  In the short runs of wire in point-to-point tube circuits, the use of copper or silver or even gold won't make a bit of difference that a human can discern; thus, no double-blind testing.

Speakers make the most difference in what you hear and pretty much any reasonably quality amp won't.  I was taught that making speakers was as close to making actual musical instruments as possible.  One of his volunteer consultants was a physicist who did the vibration analysis on violin front and back plates to determine the optimal shape, mass and thickness profiles to produce the best sounding instruments.  The Bose Wave Radio speaker set-up is a direct rip-off of my old boss's expired speaker patents.

Buy decent source equipment and a good amplifier and the very best speakers that you can afford that sound good to you in your listening environment.

I've seen the audiophools argue over what type of finish to use on their replacement wood knobs, AFTER they argued for hours over which type of wood to use.
After all, real wood knobs, of the correct type of wood, properly finished, make your equipment sound MUCH better than the original metal or plastic knobs!

While $500 is a little too optimistic, there's certainly a large margin in there Wink

The hardest thing to find about homebrewing SET amps are the air-gapped output transformers. Because so much of the frequency response is determined by the OPTs, you don't have as much flexibility with them as you would with a PP amp. They aren't cheap.

The WAVACs are well into the stratosphere, though. I haven't heard anything that expensive, closest I've come was a pair of Audio Note 211s, 50W per channel. Made me feel pretty good about my homebuilt monoblocks that I have less than $800 in the pair Tongue
