Glad to see people getting some value. I've a plan to substitute an 1L6, obviously adding a parallel ballast to have 50 mA. I've found that the 1j24 has much lower anode capacitance than the DK96, DK92 and DF96. Possibly other electrodes are also lower capacitance. I did my last DK96 and DF96 ersatz with a small trimmer and fixed capacitor on the anode and then was able to swap without re-alignment on a simple MW/LW 125mA set. The DK92 has the wrong capacitances to replace the 1L6 on the higher frequency bands, otherwise despite the different design and pin names it's pin compatible.
So I've wired up a pair of 1j24b to replace the DK92 and I'll try it on a Pye "world band" set before the RCA, Zenith & Halicrafters I have that uses the 1L6.
However I've been busy writing & editing fiction.
