FL-Line Amplifier Cabinet

The TT-15FL uses an Eimac 3CX10,000A7 tube in the Visual PA where as the TT-25FL uses an Eimac 3CX20,000A7.  Due to the higher current drawn by the 3CX20,000A7 tube the TT-25FL requires a larger filament transformer.  The only physical difference between the two tubes is the diameter of the anode, therefore all the finger stock is the same except the anode contact ring.  All other cavity parts are the same in both the Aural and the Visual.
