heeeelp please audio reserch 5SE - resistor blew up

hello

its not under warranty it was fixed in the audio research .i want to try to fix it here because i think that only thing that was burn is that resistor.
i dont know the value .is there any way to attach a  pic here

thank you

i want to change the resistor but i dont know the value.
the other tubes are different so i dont know if the value of that resistor is the same like others.
there is only one 6550 tube and the other are 6h30.that why i a looking at someone that have the ref-5SE and send me a picture .my mail is : view63@gmail.com
thank you all very much guys

hey guys

thank you all
i found my problem on the 5SE , there where 4 zener diode on the other side of the board that was open .
after replacing them the pre amp works.
i have a question  for you , i found that when i swutch from balance to rca , and there is no rca interconnect is plug in i can ear music that is very low . is that ok ?
and another thing , i put a new set of 6h30 and 6550 from sovtek
and the sound is bad , does the tubes in break in before it start to sound right
thank you
