Info
EL60 is 9 pin LOCTAL same as EF50.
The EL60 is a smaller version of the EL37.
The EL60 is basically an EL34 on a Loctal base.
The valve I use has the same gain as the EL34 but with reduced voltage and on the more common 8 PIN loctal base - (ie .same base as 5B257M - which was a 12V heater version of the 807).
h-h pin 1 & 8
*(2) 4 7 K or
3 g2
5 6 g1
tc Anode or *2 ANODE on non TC version.
On this version shown in photos on the other thread.
(11W Anode dissipation)
h-h pin 1 & 8
2 Anode
3 g1
4 g2
5 6 Not to be used.
7 K-g3.
heater current 0.8A
heater current 807 0.9A
heater current EL60/EL34 1.5A
heater current 6V6 0.4A
This shows the various valves even in Loctal-8 are not interchangeable without rewiring sockets unlike Octals.
Changing from 6V6 to another output valve increases heater requirements in some cases by DOUBLE or more.
