Post Not sure with voltage checks 
Hi all, received my kit the other day (thanks Brent) and started to put it together tonight. All has gone well so far but i do have a small issue that has got me a little confused. Bare with me as i hope people can understand what i am trying to say.

Fitted all the power supply components and hooked up a 9v battery as described. Reading at GND +V-supply is 8.08V
Verifyed 4.95V at test point between D1 andR9
Varifyed 4.95V at the GND and +V-supply pins at U1
This is the voltage check that has confused me a little, " IC1: verify approximately +V-supply (about.6 Volts lower than +V-supply) across the IC1 CD+ and GND pins" the voltage i read here is 7.4V.

Does this sound correct

Thanks

Mik

Yes that sounds fine as 8.08v - 0.6v equals 7.48v, so your very close and nothing sounds out of order here. The 0.6/0.7v voltage drop is due to a diode in the circuit.

Thanks for the reply nitropixie never hurts to ask if your a little confused at 2:00 in the morning . Anyway finished the unit of tonight hooked op to desktop and all seems to be working fine. Just one small question thou is it as simple as unplugging my V3 and plugging in the V4.

Thanks Brent another satisfied customer

Not quite. The V4 molex has more pins than the V3 molex so you will need to attach the V4 molex to your loom I'm afraid.
