[Heathkit] SB 102 - 7W Audio board resistors

[Carlos A Archilla]

Hello to the list:
I was lucky to find resitor (Part No. 3-15-7) frying about 5 minutes after I turned the old SB 102 on. It is clear that the 1K ohm 7W resistor must be replaced and maybe the 2.5K ohm 7W (3-16-7) resistor next to it too.  But before I do.....is there anything I should check other than the Power Supply 300V B+ line?  Any known source for these.  Any help would be appreciated.
