Sensibly equivalent¶ to:
The CV4049 and the B7G based version the CV4007 are special quality double diodes. The commercial versions are the M8237 and the M8212 on a B7G base. Electrically they are the same. The prototype was the CV283, commercially the 6AL5.
The maximum PIV is quoted as 360 Volts.
The anode of each section is virtually flat with a very small cavity for the cathode.
The thin glass tube envelope is 18 mm in diameter and, excluding the 7 lead-out wires is 38 mm tall.
