well, still not much clarity vis-a-vis the 6N1. Kevin Kennedy, who's something of a Russky-tube-o-phile (and a talented designer & builder) said it's just a lower-quality Chinese variant of the 6N1P. The 6N1P itself essentially is a 6922, although it requires twice the heater current.
For fun, I dissected one of those goofy tube cages on the "Monoprice" amp, extricated a 6N1 (labeled on the tube as "6N1-J") and tested it as a 6DJ8 (6922). Both sections tested good.
Doesn't really prove anything, especially since I used an emissions-type tester... but the result is at least not inconsistent with the notion that it's essentially a 6922 workalike
I wonder if I can figure out how to do something with the Bluetooth on it? I am pretty... shall we say... low tech. ...or is it old school?
Doc, when I was first getting set up, I picked up a couple of those Bluetooth receivers. Most seem to offer optical and 3.5mm/RCA out. They worked pretty well for the connectivity, and sounded pretty good for streaming music from a smartphone or tablet, so if you're just looking to play de myooziks and not necessarily critical listening, might be worth a shot. I used the Iogear TuneTap, but Oligoprice(s) probably has something less commit-ty. Also might offer the extra spark you need to get this fire started, since Johnny 4 seems to have fizzled (or is a sleeper).
I must have missed the requirement that only members with more than 1 post could participate. Sorry about that Mr. Ho.
That was a requirement, but the real issue was that the karma had already been over for a while, and the amp was being shipped out. You were late to the party.

If you're reading this, I've put up devices for a week; maybe more. I'll talk you guys later!
I've always thought the goal of high-end audio was not to have your neighbors bang on the wall and say, 'Turn that darn music down' but to have your neighbors bang on the wall and say, 'Tell your friends to go home and you can practice later this week'.
So -- according to the aforementioned Kevin Kennedy, the 6p15 power pentode is equivalent to the 'western' EL86/6CW5.
As an aside: the Russian power pentodes just confuse me. It appears that the "Svetlana" branded "SV83" of the 1990s (and used in Steve Deckert's SE-84 "Zen" amplifier) was a relabled 6p15-ev The "ev" postscript refers, I believe, to ruggedized, "military-grade" variants of a tube type.
At any rate -- I looked up the 6CW5 and it's a cool tube. It was a fairly late vacuum tube development for series-string TVs but also for hifi. It is EL84-esque, but rated for lower plate voltage. It requires a gob of filament current, too (0.76 A @ 6.3 VAC). NOS 6CW5s are cheap!
There is nothing standard about this little beastie
So -- today I gritted my teeth and hooked it up to the Frankenaltecs.
With really simple, really well recorded music -- it's not bad. A little bright, and without the depth of SE 2A3 on these loudspeakers -- but not bad.
As soon as the music got a little complicated, it started to get two-dimensional and hard/glassy sounding. And very bright.
Now, in fairness, the Frankenaltecs are adjusted for the "Simple 2A3" amp's behavior - - and that amp is doubtless rolled off in the treble... but the pairing of the Monoprice and the Frankenaltecs really isn't a propitious one. It wasn't awful, or even embarrassing -- but it wasn't compelling, either. The nominal 16 ohm load the Frankenaltecs presents might have played a role, too.
I will try some other decent quality speakers on the MP amp anon -- meanwhile, I'm
listening to Patty Larkin's 25 on the Frankenaltecs via SE 2A3 and lovin' what I hear.
Well, semi-fleapower @ 3.5 watts per channel. Good for loudspeakers with ca. 100 dB per watt at 1 meter sensitivity.
The flea-power-diest amp here would be the Decware Zen SE-84B, which runs EL84 or 6p15-ev ("SV83") output tubes in triode mode for about, maybe 1.5 watts per channel or so. Nice sounding amplifier, but it could get congested playing little girl with guitar music on the Cornwalls at what I'd consider moderate volume in a moderate sized room (our MA living room).
I didn't know you could get em on Amazon. I bought a few bags of 'em at Dicks a while back. They do come in handy. I use those and also those EVA anti-vibe pads from SupplyHouse. Also great for elevating the rear of a notebook for better cooling.
More handy stuff - a roll of Sorbothane, various 3M sticky feet and bumpons, neoprene foam roll, and high density monitor isolation pads (I like the Sound Addicted ones for value/performance/quality; one of my favorite mods for desktop computer system)

"Electronic music is human sound adapting to indulge technology, and for some, it feels like the signature sound of energy. New and abstract sounds over hypnotic rhythms can conjure vast soundscapes for escape, pleasure, and transcendence."

We haven't heard from him for a while about the amp, I'm guessing that can only mean he's absorbed in pure aural bliss. Completely overcome with emotion and re-listening to all of his favorite songs!

1) has anyone determined that the current Monoprice morph of this amp (these amps? maybe the 50 watter too?) actually still does supply too much heater voltage to the tubes?
2) If the heater voltage is OK, has anyone tried 6922 tubes in lieu of the 6N1/6N1-J/6N1P dual triodes in one?
I guess I am gonna have to get up off my -- well, you know -- and get the DMM out & measure the frickin' filament voltage(s)!

It's my pant size as well, coincidentally.
Few days ago the wife and I were relaxing, drinking wine, looking up at the night sky and she said " Look, I think that's the space station".
My mind immediately went to Doc Hardy and I thought to myself it couldn't be the space station. Only Monoprice gear has a trail like that.
