Extras ▼

 

The 6GU7 was designed for use in the matrixing circuits of colour TV receivers. It is said to also be useful in phase inverter, multivibrator circuits and as a general purpose amplifier.
This exhibit differs in construction to our other Admiral 6GU7, especially in respect to the cooling of the control grids.
The Admiral name, this time in orange-red. The anode is much longer than most double triodes. The control grid supports are made of copper.
The control grids have heat radiating fins attached at the top.
The thin glass tube envelope is 21 mm in diameter, and excluding the B9A base pins is 47 mm tall.
Reference: Datasheet. Type 6GU7 was first introduced in 1963.
