Hi,
I have a LSS for retubing but what I noticed is two of the bias resistors are cracked and one of them is burnt although it measures ~30 Ohm.
From color code it looks like these are 100 and 470 Ohm in parallel but I can't figure out the burnt one.
The outer pair of tubes are drawing ~67mA each.
I would appreciate if someone can tell me or confirm the value of that resistor and whether the current draw is normal for that pair (the middle one draws ~45mA and has a common 110 Ohm resistor).
