All the D-Fets hav shipped!
All of the SemiSouth's have shipped.

I have plenty of extra matched SemiSouth R100 pairs.

I may have a few Depletion Fet's available, but want to make sure they receive their's first. This can take a few weeks or more.

Hi Tea-Bag,

all semisouth´s have shipped...... must I be bothered, because I did not get mine up to now?

I intend to exchange the IRF240 with Semisouth in BA-1, I have four from Magura and four from you. I would need four more, but matching the new four with the 8 old??

best regards generg

gernerg, Sorry these took so long to get. We had a several month lead time.

The one's I sent you are matched at 1.57vgs @ 1.3A at 24V.

I would suggest using a two set's of four on the negative rail. (output) You don't want the R100's as the current source.
You can lower the source resistor to .5R or .33R to bring more current to less parts. I can of course sell you more parts, maybe a set of sex with close Vgs, even two. if you want to trade your's back.
I would of course try to get a channel running successfully before ordering more. Make sure it's what you want to hear!

hi tea-bag,

well spoken! new for me is the information that I don´t need R100 as a current source. I can keep the IRF? that would be fine!
And I will try four at first and lower the source resistor and hear how it sounds.

well spoken! thanks!

The waiting was no problem for me, the time waiting for the other Semi with Magura was much longer. I only wanted to know, if you send mine to me (I suppose you did so) because I did not get them up to now.
