new to tubes

[boyesreef]

well when i got it it would run the clock but that is it. actually all i had to do was plug one of the tubes back in. it had creeped out fat enough that a couple poles werent touching. had a problem yesterday though. ive used the radio for a few hours before this point, but yesterday about an hour and a half into listening i got an audible pop and a wall of blue smoke from the back of the radio. but the radio continued to play. of course i unplugged it right away, and this is what i found.







any ideas on the value of this unit, and what it is (resistor is what i think)

it was connected between the blue box and the chassis.
