Plate Voltage and Amperes meter installed on front panel, it fit well and look good.
The meter at right hand side showing 2050 V DC, scale need to calibrate later.

GI7B Six Meter Amplifier Project - Update 5
The high voltage supply was wired up.
AC 220V input to primary winding (240V) and secondary measured at 800V tapping is 730V. After rectifier and voltage doublers, measured at 2050V DC. It meets with the plate voltage of the GI7B.
The soft key and bias board PCB is mounted at the bottom, nearby the T/R relay.
