Hi everyone, Recently I've been able to find some 3LF4 DHTs around. I wonder if anyone traced this tube's curves in triode mode?
Thanks in advance.

Thanks in advance.

From 3LF4 data-sheet by Tungsol
"Ratings and characteristics are identical to type 3Q5GT"
L-octal Base is only difference, and according to my experience this type of base and socket are with slight more quality than same tubes other base?
Note that in same PDF for 3LF4 polarity of the heater pins are marked too, and it can be used in serial or parallel connection.
.
Someone measured 3Q5GT in triode (G3 is internaly connected to kathode, so G2 is connected to anode)
.
there are optional settings. And spice models. One for DHT same for plain triode.

cheers

I had one other question; Can this tube be used as the driver stage for a 2A3 in SE or maybe 4P1L in PSE mode; Resistance loaded with Va = 90 V and Ia = 13 mA?
