Default where to find 5998 ?

Hi,

I am considering to make a headphone OTL amplifier - one stage only-
for high impedence type like Shennaiser.
I have thinked, why not a basic 5998 ( 1/2 for channel) in common cathode mode ( like 1930 )?
Eventually, I can place a chocke load, no? ( only if indispensable)

A fast research in e-bay say nothing, zero for 5998!
Is it so rare?

every comment will be appreciate,
Thanks,
Paolo

Look for 7236. Same tube with computer ratings. I got several from Ebay but it was a few years ago.
