GI7B Six Meter Amplifier Project - Update 6

Logan (VR2XRW) gave me a 10mm ferrite rod for the filament choke, it is in place all together with the input tune, consists of two Arco variable capacitors and 15mm dia. coil.

The GI7B tubes are in place. They were supplied with the filament votlage for few hours.
