2 times power triode 3-1000Z 160-10m Amplifier
This homebrew 2x 3-1000Z grounded grid amplifier is designed for 4KW PEP input for SSB service on the amateur bands between 1.8 and 29MHz
Back an front view, removable.
The amplifier is entirely free of regeneration or parasitics.This amplifier is also service friendly with easy access to all components.
General components placements may be seen on the bottom of the shielded enclosure.
Shielded wires are used on all low voltage leads. Silver plated copper strip is used for all taps.
