the pinouts couldnt be much more different... frustratingly.
Thanks, I saw that. But how can this say that it's an exact replacement for a E182cc when it's clearly not according to those pin outs?

Very nice, with Teflon caps!
Is there any difference in sound between 8412 8414 receivers?

Also guys can you please recommend a freeware Crossover design software?

Default BOZ or JFet BOZ for line amplification

I might be cursed and thrown out asking this in a thread with so many tube lovers

Did somebody try a Bride Of Zen ( BOZ ) approach for the line level amplification?
or it's JFet counterpart Jfet BOZ (Lineup version with a bit lower THD ~0.06% or Nelson Pass version from 1st page) ?
In simulations both versions have a very nice, monotonically decaying THD spectrum, as tubes do, with THD from 0.06% to 0.2% depending on parts used.

I don't want to start a dispute between tube vs. fets, just from pure curiosity, as it costs almost nothing, only a good output cap.

Thanks.
