BC-610 I, AN/GRC-26

BC-610
I got this BC-610 a few days ago. I got first all the tubes and cables.
Two days later I got the rest. I don’t understand what I got before I start the work with all the parts home.

This is a 400 Watt CW, AM and RTTY amateur radio transmitter designed in 1938.
It was improved in 1942 for use in war. Watch the video.

The BC-610 is very heavy, so I mount wheels on it.

I have also NOS tubes for the transmitter.
