Description
We have chosen the best of the best L63 for you to buy and be safe with the purchase. It is high time to show one of our favourite valve, the Marconi L63 6J5G with white lovely red and green logo/seal on glass.
The L63 was first introduced in 1938 as a valve with octal base made by the MO-V.
The American counterpart was named 6J5G.
With 6.3 Volts heater it is basically half a 6SN7GT. Basically two L63 make one 6SN7GT!
