[Amps] Wire Gauge

[kk4tr]

Hello there again.
    Does anyone out there know the gauge of the wire that is used to wind the plate choke on an Alpha 76 Amplifier??  I need to rewind the choke but I am having a bit of trouble finding the size of the wire to begin with.  I think it is either 20 or 22 gauge.  If any out there knows for sure I would really appriciate the help.  The ones sold by RF Products and  Ameritron are smaller gauge than the one used on the alpha.
