Upon start up it makes a very loud growling noise (maybe a very loud hum is better description), if you let it stay in this condition a house fuse kicks off.  It would seem that a short is occurring somewhere, but I have not been able to determine where that is!  I have replaced 3 of the 6 diodes on the rectifier section and even went so far as to replace the SCR, but no luck.  Does anyone have experience with this type of problem and are there any manuals out there for this beast?
