Figure 7 properly wired back panel dropped
Note: Incorrectly wired panels will not drop without unsoldering multiple transformer wires, and perhaps coax
and other leads. It’s advisable to take a picture of the panel with wires attached to aid in reassembly of the
panel. Be careful unsoldering leads. Leads are accessible through a plate on the back of the back panel. Use a
large iron, and have a solder sucker or solder wick handy! Use a large hot solder-wetted tip on the wire ends
that stick through the boards, so you can get on and off the solder joint quickly. Do not linger and overheat the
printed circuit board foil while waiting for the wire to melt free. You do not want to lift foil pads off the boards
from excess heat. Heat the wire end with a wetted tip flat against the wire, do not heat the foil.
This is an incorrectly wired panel. The transformer leads are too short to allow the panel to fully lay down and
must be unsoldered for input board or tube chassis service. Figure 8.
