Description 5R4WGY:
The 5R4WGY is a powerful, full wave vacuum rectifier tube, direct heated with 5,0 VAC, 2,0 Amp., designed for max. rectified DC_output = 285 mA @ U_input = 2x 700 VAC in full- wave configuration with capacitor as first filter. The 5R4 with WGY-suffix tubes are ruggedized, shock resistant, usable at high altitudes and have a high reliability over a long lifetime.
For more technical information see *)
Condition:
Unboxed, used, but in good condition, apparently free of mechanical and electrical damage as well as of gas. The emission of both partial systems of all 3 tubes each is "very good" .
Emission tests:
All partial diode systems were tested with the follwing parameters according to *):
U_plate = 45 VDC,  U_h = 5,0 VAC; the index value (=100%-value) of I_plate is 150 mA
Results of the partial diode systems:
I_plate = 99, 103, 106, 108, 109, 110 mA
==> very good
The results/partial diode are written on the bottom of the tube sockets.
