First Watt J2 installed

[WalterW]

I will wait for the release of the version from Mr Pass. I have the output devices waiting. And wait I will. Not hard to do, already having the M2. It is a treasure as well.

I collected up the JBL drivers (that were specified at the time) for the 7pi, but lost interest when EconoWave was raging. Still have the Ewaves, starting to regret selling those JBL drivers.

Same here, Semisouths are waiting🙂

Any equivalent parts are available for semisouths ?

 

[vdi_nenna]

There are power jfets available, but if they are viable for audio is better recommended by someone else.

JFETs new at Mouser...

Through Hole TO-247-3 N-Channel JFET | Mouser

I though the input and output capacitance was high, but it's less than the SemiSouth SJEP120R100A audio version of their Jfet.

No good.
You need enhancement mode parts.

 

[vdi_nenna]

No good for J2, correct?

Ok for DEF?

Ok for DEF, no good for J2

 

[vdi_nenna]

Not all bad news...🙂

If that's the case, I'm a sissy and proud of it! 😀

I know the company went out of business but are the output devices available for purchase?

I got mine from a member here, I believe it was "Semisouth"?

I checked his profile and his last visit to the forum was over a year ago. It seems as if I missed the opportunity to buy SJEP120R125 devices.

🙁

 

[Nelson Pass]

Sorry to say, I don't have the R100's for sale. I have, however, built some
nice versions with IRFP240's.

 

[2 picoDumbs]

I built a turbo version using a single pair of IXTH64N10L2 biased at 2.6A

Still haven't tried the SiC hockeypucks it might be fun to try them out on this amp.

 

[JeffYoung]

I got a quote for SJEP120R100's: $122 each at qty 12. That's $1500 for 3 amps. (They each take 4, right?)

Yowza. But those FETs were expensive to begin with, right?

 

[samoloko]

can you get a better quote with more qty
we can do a GB
