Not bad value! Like it then? Let us know. You got it nice and cheap anyway!


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

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

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.

There is one more small double triode shared between the 2 channels,
which I GUESS drives BOTH the "magic eye" level indicators.

There are a total of 18 triodes shared between both channels, plus
the "magic eye" indicators.

What are all those triodes (8 per channel in total) needed for?!
