Can Anyone figure this?

Hi Guys
One of the local electronics chains will be selling an amp that runs a 6n1 input and a 6p15 it think its called.. essentially the equivalents of 6dj8 and el84 respectively. The claim is 25w rms but with a single output tube (the 6p15) I just cant see how you would get anyware near that.. For a start it is single ended OR is it driving a ss stage i wonder.
What say you?

Missing decimal point? 2.5W? Or it could be as you suggest, an IC power amplifier intended for televisions preceded by a valve effects chain.

a 6N1 is bascally an ECC88 and the 6P15 an EL84.
a maxed out EL84 glowing orrange can manage 7watts rms for a short while. More like 5watts rms for a reliable setup.
Methinks they are quoting music/peak power for both channels and even then a bit obtomistic.

It seems the DECWARE SE84 is being "knocked off". That's not a bad idea, but give Mr. Deckert his due.

I have got the local store to put one aside for me when they arrive mid year. There is no way this is 25 W RMS although the decware one does produce 12.5 watts but you would be running that poor el85 fairly hard.
This is a case of I will blieve it when I hear it and then pull the bonnet off and see if there is any sand.. err silicone in the power stage.

Was it one of these...?

I saw a VTi-B1 the other day while in London Drugs. Looks cute. Maybe something a teenager might have on her shelf. It's apparently a stereo unit. Since there are only two output tubes I guess this would imply it's single-ended..?! Seems optimistic to report "15W x 2" and "50W max" per channel from those dinky 6N1s. "The Amp" looks like it could be taken a bit more seriously. Impossible to tell without seeing a schematic or knowing the quality of the iron.

It might also have something to do with "Music Power" watts or what ever they are calling it now a days, versus real RMS watts. I have some 6 inch car speakers that actually say right on them "500 watts". Yeah, maybe for a microsecond.

Typical sales hype methinks.
Probably has semiconducter output satages if the wattage is correct.
There is no way one can tweak 15/20/25 watts rms from an ecc83.
Looking at the photo's it seems to have two drivers (6n1's) which are low level dual triode preamps and what looks like an em84 fluorescent bar display tube like they used for level displays in older tape recorders.

Look at the specs, says nothing about el84's

Yep. kind of reminds me of some 200w computer amp and speaker
combos I once sold at a computer store. Funny the wall wart power transformers for these 200w speakers were rated for 20w.
