The 6F29 (equal to the EF183) is a high gain variable μ RF amplifier pentode. It is a 1960s design and superseded the 6F26. The 6F30 was the straight version of the design and replaced the EF80. All four valves have the same pin connections.
The valve performance figures are given at 40 MHz and the normal TV IF frequency was around 33 MHz.
Through the screen the anode can be seen as two small plates joined by a strap.
Made in England and a member of the BVA.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 54 mm tall.
