Checked out the power transformer...
Schematic calls for:
7 ohms @ input (wht/wht), measured 10
>.1 ohm @ ground (blk), measured 1.6
170/180 ohms on the output legs (yel/grn/yel), I measured 130/140
I'm spelling it out in case I did something not-quite-right. These measurements are with the rectifier out...
AND...
Another rookie mistake. I also forgot to check the windings on the output transformer. Gives the impression of being open on all counts. Dead, dead, brown bread. I suspect this is why I had the problems I had... I guess my next step(s) are to check the other chassis to see if, against odds, my transformers there are viable/closer to spec, or to start looking for replacements.
Any advice, coaches?
