red knob twin fly wire gauge and voltage rating

[jalexquijano]

Can anyone point out if the fly wires that go from the 6L6 power tubes to the PCB and from the 12ax7 preamp tubes to the PCB are 22 AWG 600volts or smaller? Solid Core or Stranded?

From what´s on another post looks like original ones are definitely not so, but these you mention will be an improvement, which is fine.

In any case, always stranded , never solid core.
