I built Martin Kings OB and was planing on biamping it using this amp from 500hz up. So the subject of a crossover comes up. This being a current source amp I could use the circuite Nelson has in his Current Source Crossover Filters article after recalculating the inductor and cap values.
FIG 5A But in my case I won't be using the woffer output can I simplify
the woffer part of the crossover.

The SIT parafeed is performing great! I assume the better quality
parafeed capacitor contributes to the whole quality a lot!
In summary I would say it is a good mix of a classic SET ala 45 and very good SS...
For me there is no other way to go now...
I encourage you guys to try it...It cost a little more but its worth the effort...

what do you call the SIT parafeed ? do you change michael schematic?

Of course I did....High voltage lines need other biasing...

By the way I am the first who build it that way, maybe even first in the whole world,
so I can call it what I like...
Let it be SIT PARAFEED.

In order to name it, you need to display it.

I'm intrigued by this cute little amp and so thought it would be fun to build among others... since the efficiency and simplicity would be nice from an inductor I'm leaning towards an 193V.

I'm thinking about the supposed ringing sound however. Would the ringing be less with one of the larger 195T5? ( 100mH, 5A, 0.64 ohm ) Or is ringing something to expect from big iron core inductors?

Or maybe an even better option: If I'm not deluding myself the total dissipation of the choke would be ~ 4W @ 24V rail voltage. Since it doesn't get that hot would it be a problem to build say a silencing box out of wood around it?

And another thing, about the inductances on the inductor vs performance: is it that more inductance is always better or that you need more to have a full range response? Say I'm also designing a tweetamp and on that one only need from 2 khz and upwards, could this one have a much smaller inductor without drawbacks or is a big one still better here?

My 193Vs don't sing or get hot at all.
