You would need to swap round the C and E tracks/connections.
Thanks S-Man.
I will have to think of the least invasive way of doing it.

Taken delivery of these (I have a brace) this week ....nice touch and no mistaking what they are.
I turn my Qudos monoblock ex Naim 110's an hour before I need them, likewise I reckon they will see me out!This finally is my dual mono Qudos which has taken a long time.
Runs off 44v and set up as per instructions 120mA.
The wiring isn't pretty and is fairly basic stuff apart from silver plated PTFE for signal output and Mogami Neglex microphone for signal input.
The big heatsink is internal but well vented top and bottom, still needs more height on the rack to keep it cool than the NCC200 Nap180 it replaces.
It is in a Mogami 8cm high case on Quadraspire with on 10cm uprights.
Sounds great though, all you could possible want. A bit lean on start up but after 20 mins is full sounding, detailed with great sound stage.
Will be my best amp I think.

Very sweet...
Can we have a shot from above please?
Ta.
He does make a lovely pcb.
Bit grainy (off my phone) but should help...
Ta. That's brilliant. I'll start decoding the resistor bands when I have a little time later this weekend.
So, from I can make out Les does appear to be building new boards with, R4 & R27 @ 27R and R5 & R26 @ 15R. C9 & C10 are 4.7nF.
Question is now, is it worth getting the old soldering iron out??
From my discussions with Les, it's more an evolution than a revolution, so I suspect the change would be modest. I believe that C9 and C10 are in fact optional, so the exact value is likely to be non critical.
