The 6X4 HT rectifier follows the normal pattern for a full wave device in that a common cathode is employed.
At 325-0-325 input to the rectifier this will give an HT rail higher than is required for most domestic receivers. Use for audio amplifiers and small transmitters is most probable, or driven at 250 volts for radio receivers.
The 12X4 is electrically identical and was developed for use with vibrator power supplies in car radios.
The central tubular cathode has two black anodes set at right angles to maximize heat transfer.
See also EZ90 from Brimar, and the CV4001 'reliable version with flying leads.
The thin glass tube envelope is 17 mm in diameter and the length, excluding the B7G base pins, is 56 mm.
