ALFET MOSFET give away (ALF08P16V + ALF08N16V / 2 pairs)

[SomekPoland]

And I assume the L stands for lateral... Show us what are you cooking Papa! I'm hungry!

Patience.

Sort of late to the party, actually didn't want to put my name in the hat as I wouldn't be able to take advantage, but just revisiting and Am very intrigued by, are any quad sets still available?

 

[gaborbela]

I wish I could have 2 pairs also...

 

[Nelson Pass]

F5L will have 2 pair. Following that at some point will be Hitachi TO3 laterals.

Plz Papa, I won't tell anyone! Where can I find the other two pairs of Alfets 🤣

 

[gaborbela]

SomekPoland I think we are late to the party.

 

[SomekPoland]

Well, I can always build it with 1 pair per channel and have a killer headamp

Hello dear friends,
Did I get a lemon?
Am I that lucky?

Nelson, looking into the future, when you mention the Hitachi TO3 laterals - will we be looking at at an N/P pair per channel, or do you envisage maybe 2 pairs per channel?

I assume the 2SJ50 / 2SK135 will slot right in.

 

[Nelson Pass]

I have store UMS brackets with 4 sets of holes. Likely that would be 4 devices per channel.

I also have the TO220 lateral drivers for those, and a 3 stage circuit with Toshiba Jfets looks attractive.

 

[gary s]

That all sounds very interesting indeed. Thanks again Nelson for the info.

Would the driver laterals be from the Hitachi J76,77,78,79 / K213,214,215,216 series?

So this could be an all Toshiba Jfet , Hitachi lateral fet amp with no BJT's in sight - very original!!

Found this Hitachi circuit from years ago.
