Gorgeous JTM 45 amp , incredible tones , sounds really huge ,  Holy grail  .

Shipped in  flight case .

Some improvements have been made only for the safety of the device:

• High voltage secondary fuses circuit.

• Use of a two-pole switch for mains.

• Installation of the mains fuse on the phase.

• Removal of the polarity reversal circuit linked to the phase switch.

Two improvements have been made which do not affect the sound:

• Replacement of the carbon layer resistors (source of noise) feeding the anodes of the preamplifier tubes with military grade Dale RN70D resistors with very low noise levels.

• Improved bias adjustment circuitry to allow precise adjustment by potentiometer accessible from the rear.

All wiring is done with NOS single-stranded wire made by Belden.

All soldering is done with silver-filled Stannol tin to prevent oxidation.
