Silverfoxvtx1800 Posted December 20, 2023 Share Posted December 20, 2023 Hello, The production of the Sit-4 starts soon, wondering how everyone likes First Watt the Klipsch speakers…I have the Forte IVs… Quote Link to comment Share on other sites More sharing options...
henry4841 Posted December 20, 2023 Share Posted December 20, 2023 I was not aware there was going to be a SIT-4 from Firstwatt. Last I heard Nelson's stock of SIT's that he had produced were depleted. Is there going to be a new product using NOS V-fets from the 70's? I know of no company producing static induction transistors for the public. My understanding is they are still being produced strictly for the military though. There was a rich guy producing SIT's in Japan before the tsunami but his factory was destroyed. From Firstwatt's webpage. https://firstwatt.com/wattsnew.html Watt's New? 2/5/23 FW Product availability: As we run low on the SemiSouth SiC Jfets and SITs without replacements, we are discontinuing the F8 and SIT-3. F7 is still available, and new product is under development. Quote Link to comment Share on other sites More sharing options...

New to me and thanks for letting us know. There is a lot of activity of members at diyaudio.com building amplifiers using those Tokin SIT's but I have not been following the threads having both the PP and SE version of a SIT amplifier. The transistors alone are selling for $100+ on Ebay. I also did not know Nelson was sitting of enough of the Tokin's to offer a production SIT-4. Sneaky grey headed fox. The SIT transistors he had made for $300,000 years ago are no longer being produced. The company closed. These SIT amplifiers by Nelson Pass are destined to be a classic desirable amplifier 20, 30+ years from now. He is one of a kind. He will service any amplifier made by him at a minimal cost after the warranty has expired. Even the old Threshold amplifiers or yesteryear. Transistors made 50 years ago are in demand and work as when produced. Quote Link to comment Share on other sites More sharing options...
babadono Posted December 20, 2023 Share Posted December 20, 2023 $4000 for a 10 watt amp...does it really sound THAT good? Too rich for my blood, I won't be able to discern the difference. Quote Link to comment Share on other sites More sharing options...

Too rich for my blood, I won't be able to discern the difference. $5000 And usually a waiting list to get a Firstwatt product. Quote Link to comment Share on other sites More sharing options...
Silverfoxvtx1800 Posted December 20, 2023 Author Share Posted December 20, 2023 Definitely a little expensive….i am trying to get a tube sound with solid state , lately not happy with tubes… Quote Link to comment Share on other sites More sharing options...
henry4841 Posted December 21, 2023 Share Posted December 21, 2023 Try a tube preamp with your SS amp. It will give you a touch of 2nd harmonic that SS amps sometime lack. Audio amplification is entertainment, art, as well as science. Most input tubes have very little current being run through them so replacement will not be needed for years.
