Is there a diy project that can use the Lundahl 1539s as a line amp/ balancing unbalanced outputs?

I have some 1539s flying around and would like to use them. Are there some diy projects that use this?

It can probably be used instead of the LL5402, just different pinout. Quite a few projects for that..

Thank you! I'll have a look. Just saw your pultec project- that one looks super nice!
PS: what do you think of the antelope emulation of your preamp?
