check the horizontal output transistor for short then replace a 60 watt light 
bulb in series with the 120v ac power line and try again if light bulb lights 
up you still have a short on the main b+ line ,replace low power rectifiers 
ecg 125 and replace reg transistor then replace 10 watt resistors ,use 60 watt 
light bulb in series with main power line before you plug it back in  dissable 
the horizontal drive  by means of disconnecting the horizontal out put 
transistor  then plug power into ac varriac  or variable ac supply  bring up 
and watch light bulb also monitor ac power not to go over 90 volts ac with 
varriable ac  control  if light bulb doesnt light up while doing this test you 
may have found your problem in the highvoltage output 
(this is the way i would trouble shoot the system rember as long as the light 
bulbs burns theres still a short somewhere in the system
