Not bad value! Like it then? Let us know.


Yes, indeed I do!

Like I said, when I switched it on, it came at me like silly great Labrador
and has been slobbering all over me for the last 11 hours!! :-)

It looks happy as Larry and is no warmer anywhere than 'comfortably warm'.
Hum is very low - negligible - and the whole thing looks very solidly built
(16 kg) and really quite well finished off. The trannies look quite
substantial through the ventilation slits - no guarantee of quality I know,
but the sound quality (specifically the bass) has already reassured me that
they aren't totally ****e. The valves do look a bit 'Chinese' (no offence,
Tat...) but they seem to be spot on. Too soon to make remarks about 'sound
quality' but I will say that if it was the only amp I had, I'd be *far* from
unhappy with it, believe me. (I'm quite tickled that the sound is more or
less *exactly* what I expected!)


You got it nice and cheap anyway!


Yes, that's the main appeal isn't it - these amps look to be very good VFM
and I can only say that, so far, it seems they most definitely are!! In fact
if it went tits-up I wouldn't change my opinion of it, I'd just fix it! -
Especially when me mate Shiny Nigel's brand new megabucks EAR834P (over £500
retail now, I believe and which he waited at least 2 sodding months for) ran
for a *whole* week before crapping out on one channel!! (This little bugger
comes with 12 months warranty any way - in German!! ;-)

Incidentally SN's shop has got a Copland in that's had a valve *burst* (???)
inside it, apparently - he reckons it looks dead cheesey inside, no apparent
'quality' anywhere!!!???


I'm intrigued by my also-cheap YaQin. The circuit must be WELL
complex compared to most cheapy valve amps. I wonder WHY.


Yes, it's a mystery - why 'over-egg' the pudding? I'm afraid I don't know
nearly enough about them (yet) to offer a meaningful suggestion.



I mean it's push-pull, and has 4 o/p valves, BUT each o/p valve
is a DOUBLE triode.


Possibly/maybe 'cross-wired' (or whatever the correct term is) - ie both
triodes in the same envelope 'commoned'...??



The driver valves (1 per channel) are also double triodes.

There is also 1 more small double triode per channel, driving the
driver valves mentioned above.


One set will be the phase-splitters (?)....
