Ant one have any good quality pictures of the bottom side of this rig? Or have a rig torn down at the moment? Had one come into the shop today with the final tubes removed. one was cracked. He had took it to another tech that just started pulling stuff out and he stopped him. There was a burnt component under the tube socket that has been removed. By looking at the two pieces I can not tell if it was a resistor or a diode let along just where it was mounted at. Oh, has anyone ever replaced the 6JS6 with 6KD6? My info says they are the same.
