Nice one Alan, your hunch for these little Chinese amps has paid off with a few adjustments!

It's not actually so little James, I think it weighs 22 kg.
It has quality iron on it which gives the great performance.

Yes it's now being used as a power amp.
As built it has 3 sets of inputs running to a selector switch, then to an inferior volume control, then to the input stage grid.

I have fitted a relay to isolate the inputs and volume control, with additional sockets feeding the input stage directly.
It is surprising how much a conventional volume control strangles the performance, I and others have moved on to quality stepped attenuators, either Khozmo or Acoustic Dimension. These let the music through, the pre I am using is my active KIN which now sports an Acoustic Dimension attenuator.

It's a shame that Ming Da don't fit a quality attenuator as the performance cries out for it.

As a note, I agree with Alan, The pot is slightly inferior!
Sadly not everyone will pay for something better, they want easy remote etc. But Like Alan, I do offer an upgrade with a stepped pot, using little Dale resistors, but I agree relay and direct input to the grid is favourite!
Great Amps to "Pimp"
