o.k. hugh you said it was quiet.. I am in the last stages of constructing/testing and have more questions...
here is the latest:
I was trying to test quiescent current and noticed I wasn't getting any change in voltage... through a series of tests- I found out the fuse was blown on the IEC and therefore no power was getting to the PS board (and it took me a long time to figure this one out
.. in any case, I replaced the fuse and still have problems with current getting to the PS board. When I hardwire the transfo wires (straight to a plug) everything is o.k. and get +/- 40v at each of the DC spades.
Two questions:
Any ideas why the IEC is not transferring current? It is rated 10A 250V which has no meaning to me. I did buy the 3A fuses that Hugh suggested (the second fuse I put in has not blown yet). I double checked that I had it wired correctly (L=hot, N=neutral, E= ground to chassis).... could it be related to the fuse? or should I just order another IEC?
Also would testing at this point with a straight connected (i.e. not fused) pose any dangers? (I'm at the point where the main fuses are in each of the boards). Everything up to this point has been fine (all the earlier testing was performed like this running through the safety lightbulb box peter suggested). From the plug, I have black wire to the hot, wire to neutral, and the ground wire unattached. It might take a while to find another IEC...
patiently waiting to continue...
