Vintage vacuum tube radio frequency/RF base amplifier - Pal Ham Ten series, 201 BDX

Mid-century vintage , vacuum tube "Ham Ten Series - model 201 BDX Base" radio frequency amplifier made by Pal Electronics of Westminster, California. This is from the estate of a industrial communications engineer and short wave radio enthusiast. We plugged this in and the vacuum tubes glow. The wires on the back marked for 13.8 VDC have been cut off short and this has wear to the paint on the case. It measures about 10" x 8" x 3.75".
