I have recently become the proud owner of a new (used) Dual Rec 3ch non-multiwatt!
Just got it up and running last night after reading the extensive manual and after some testing I've got a couple of questions about things I noticed...
If I put both ch2 and ch3 in vintage mode, with all the controls at 12 o'clock, then according to the manual, I should hear a lot more presence in ch3 than ch2, as the ch3 presence control "picks up where ch2 leaves off".
However, I find the opposite is true. ch2 sounds a lot more present than ch3 at those settings, and even increasing the presence in ch3 doesn't help much. In fact the presence control in ch3 hardly does anything until you get to around 8 or 9 (out of 10), and then it suddenly takes off.
So in summary, in vintage mode, all controls at 12, ch2 has more presence than ch3, and this remains the case until ch3 presence is turned past 8 (out of 10). But with presence maxed out on both channels then ch3 does have more presence than ch2.
Can some Dual Rec owners please tell me if this is normal or does it indicate an issue with the pots (need cleaning?) or the valves (need changing?)
Oh and another thing, the output volume control doesn't do anything between 0 and 2, but then the volume suddenly kicks in big time, like turning it 0.1 degrees will increase the volume significantly. Again, normal or does the pot need cleaning?
Thanks in advance!

But I think you can 'crank' the master volumes on the channel and turn down the output level - but it won't necessarily sound good if you run the masters very high on the gain channels, from memory... but again I'm not sure. I don't think this is the same as pushing the output tubes, someone like @ICBM could tell you.

I can also say from experience (I've cranked one in a studio in an isolation booth, heard via a mic in the control room) that it sounds rubbish, the sweet spot is around three on the volume for me.
