**Not anyone with half a brain. It is ridiculously over-priced, for such a
POS. It delivers a pitiful 18 Watts/channel. It uses a couple of
bog-standard output ICs, some 4558 line stage ICs (these date back to the
1970s) and a couple of valves (which are operating at stupidly high
filament Voltages) for distortion. A complete waste of time. The valves
will not last very long, due to the high filament Voltages). In fact,
Jaycar sell a quite decent integrated amp (P# AA-0470) for $200.00. At 100
Watts/channel, it offers respectable performance at a reasonable price. No
valves though. Just decent performance at a bargain basement price.
You would have been MUCH better spending your money on a decent, second
hand, Japanese made amp, from Marantz, Yamaha, Rotel, NAD, et al. Those
guys use (in the main) all discrete output stages, modern line stage ICs
(at least 5532 class), are built to last and don't employ silly tricks
(like sticking useless valves inside) to suck in the gullible.
I trust that answers your question.

**Indeed. Nonetheless, this thing is a con-job. It uses LM -XXXX output ICs.These are closely equivalent to the EL84 power valve which can do 6 watts

Just out of curiosity, what voltage is it hitting the heaters with?More seriously, however, is the nonsensically
high filament Volts applied to the valves. I'd be surprised if they last
much more than a few hundred hours.

Its funny how people 'swear by' vaccum tubes. Mordern devices are so
clean that they sound 'worse' to these morons. Just introduce a bit of
noise and things sound better. They even found this was true when they
were asking people to tell them which mp3 bit rate sounded better. If
they added random poeple were more likly to think a low bit rate sounded
better than a cleaner higher bit rate.

**The measurements I saw were not taken with an RMS Voltmeter, but the
brightness of the filaments, compared with the same filaments operating at
the correct Voltage was clear and obvious. I'd reckon a 20-25% overload
would be in the ballpark.

If I just purchased this POS, I'd take it back. It really is disgusting.
There's one born every minute. Jaycar actually sell a reasonable amp, for
a reasonable price (Part # AA-0470). There is no need for people to buy
junk like this.
