3 fuses at $50 each plus $250 restocking fee..This will make it pretty easy to return the amp to the dealer!

Not a chance I would use a device like this missing a safety ground. Nor should anyone else. Inexcusable, this is Safety 101.
The question may be, 'how much does Bob have to do with the product manufactured?' Of course, if this is his design and it's built as the schematics dictate then he has no leg to stand on.I wonder if it hears the buyer complain, "this is a piece of under-powered crap, what a con" and adjusts the sound to convince you otherwise.
I guess Amir needs to retest with a loudspeaker and see how performance changes in different size rooms. 75 watts tube power and double that into a loudspeaker. Sounds like Bob's mental feedback loop has been redesigned. I guess age gets to the best of us, and now Bob's mind is going.
I wonder why I'm still alive after using my Dynaco MKIIIs, ST-70 and ST-35 for decades which not only don't have safety grounds, but have full B+ voltages directly exposed on the top of the chassis? How could this be?While the performance is poor, the real story here is not including a safety ground in an amp with peak voltages that likely exceed 700V at startup.

Paul originally measured potentially DIY "Carverfest" amps. He then purchased a known-commercial production amplifier from a dealer and had it shipped directly to Amir to measure. The one measured by Amir is a production consumer amplifier.In the thread on the other forum referenced earlier, the poster, apparently quoting Bob Carver, claims that the amp measured by Amir was not a commercial Carver product but was rather a hobbyist-built “Carverfest” amplifier. At least, I think that’s what he said.
You have not had a transformer or other line component fail and short to the chassis. And/or have not stuck your fingers in the wrong place in just the right way to get electrocuted. Or you are a ghost.I wonder why I'm still alive after using my Dynaco MKIIIs, ST-70 and ST-35 for decades which not only don't have safety grounds, but have full B+ voltages directly exposed on the top of the chassis?

Or maybe it was impressed upon me early on in my childhood that one doesn't stick fingers in light sockets or onto electronics which might have high voltages exposed. I think the same person taught me to not play on railroad tracks or on freeways. Apparently that isn't taught anymore.You have not had a transformer or other line component fail and short to the chassis.

This is why I’d like the short-lived Dynaco ST-70 series 3 (circa 2017) measured. It had the safety features missing from the original incarnation. The reborn Hafler company stated at the time it was the best ST-70 ever produced. Unfortunately, it is no longer listed on their website.That's simple, you did the smart thing and used the ventilated cover! You can't fool me.

My dad was a PhD in microbiology. What he knew about electricity/electronics was taught by self or me. No, not everyone understands the dangers, and I do not recall any safety classes in school. Root, hog, or die? Darwin...Or maybe it was impressed upon me early on in my childhood that one doesn't stick fingers in light sockets or onto electronics which might have high voltages exposed.

Martin,Sad… well at least I can take the Model 350 monoblocks off my list of desired products. I think I’ll refurbish my pair of Dynaco Mk III monoblocks or buy and build the pair of VTA M-125 I’ve been eyeing.

The 'safety course' I had in high school was the AC/DC radio everyone built in electronics class. It became abundantly clear because of the 'hot' chassis that common sense needed to be applied to working with anything, well, on planet earth, be it electricity, driving a car, shooting a gun, or dating.No, not everyone understands the dangers, and I do not recall any safety classes in school.
No electronics class in high school I attended. I had been a tech for a few years so understood the dangers. Maybe I was just stupid.

So….it brings up the old question of how to rate the sound quality of an amp. How does a Macintosh compare to an Emotiva or a Topping PA 5 for that matter?The Carver Challenge
The Carver Challenge
Is it possible to make a $700 "mainstream-audio" power amplifier sound exactly like a high-priced perfectionist amplifier? Bob Carver, of Carver Corporation, seemed to think he could, so we challenged him to prove it.www.stereophile.com
'the listening went on through the whole afternoon and much of the evening, until all of us were listened out. More leisurely listening, refreshed by a good night's sleep, failed to turn up anything. As far as we could determine, through careful comparisons and nit-picking criticisms, the two amplifiers were, in fact, sonically identical. It is a gross understatement to say that we were flabbergasted!'
No, and certification is an expensive process perfomed by third parties. That aside, no company selling products like this should be without it. One lawsuit, and they're done.BTW, is there no mandatory safety certification for electrical appliances in the U.S.?
