ok with all being said above im sure now the crts are bad because i said i applied 9 volts to the crt heater with a separate transformer but i had the wrong tap hooked up i had 7 volts. so now i applied 13 volts @ 300 milliamps which then the voltage came down to 9.5 volts ac and i tried this with the sylvania crt which when plugged in to the chassis the heater was bearly visable at 6.6 volts but after applying the 9.5 v the heater lit well like any other heater i have seen and the picture was bright and watchable in a lighted room. the other crt , the rca did get brighter but not much still watchable in a lighted room. so i know im done with the chassis except for the arcing from pin 5 of the 6sL7 cap to ground, maybe this is caused from bad crts, i dont know. i checked the ohms at 1-14 the heater pins on both crts and they are the same so why would one bearly light but the other seems to light normal. i could see if resistance went up on the crt heater that bearly lights but they are both the same. the sylvania , the gun at the heater looks new no marks or heater signs or discoloration from heat but the rca heater part is black and shows signs as if it has been used alot. so what may cause the heater to not light properly with the proper voltage, but rather more voltage.
