the volts are 1st IF pin 2=154 v pin 3=0 v pin 7=0 v
on 2nd IF pin 2=155 v pin 3=0 v pin 7=18.5 v
some of the other voltage are down by 20 v like # both 41 tubes are 150v instead of 175v
i ran the ohms on the transformer and they seem OK but I'm missing something i just don't no what....i have d/l the 41-255 step by step guide it's a great look at a pro at work hope i can glean something from it..{.I just retested 2nd IF and the signal gen works only on pin2 and will NOT pass to pin7 Icon_crazy

thanks
john
