• Tektronix 515a

    Hey so I recently picked up a 515a for repair and going through a initial visual inspection I found a cracked 15ohm resistor and yet I can't seem to find a single 15ohm on the schematic and I also haven't been able to find what it's connected to if anyone has worked on one of these units could I get some help. (this is on the bottom right side of the unit)
