Dynatron LF7/16 Amps
Used pair of Dynatron LF7/16 amplifiers using KT66 output valves and with associated field coil loudspeakers.
These were taken out of working radiograms.
If you want to use without the speakers you will need to add some smoothing chokes.
You get 2 amps and two boards each with 2 field coil speakers on it.
