Success!!!
I changed the wiring today and did a 10 minute bench test. NO HOT WIRES!!!. Fans are running well and the aluminium mirror back got nice and cold. The heat sinks were just warm, showing that the peltiers were working well. I used 25 amp wire from power supply to the scope and from the inside of the plugs to the junction of all the other wires.
Thanks to all for your tidbits of advice and experience. I learned heaps! Paul and Anthony, you blokes are legends! What a great idea!
Tomorrow I will flock the tube and put it all back together for a full test. I will post the results as soon as it's done.
