Z62 MO valve information
Geoff Hines

This valve was introduced to improve performance up to 60MHz, the introduction of a shorter glass pinch seal and a shorter top cap grid connection reduced the lead inductance and capacitance to adjacent connecting wires. The valve also had a higher mutual conductance of 7.5 ma/volt unlike similar RF pentodes such as the EF39. This enabled a higher frequency and bandwidth prior to the introduction of moulded valve bases such as the EF50
