Firstwatt Vfet Sit Amplifier | eBay

 

This is a Class A amp using push-pull topology, with two VFETs per channel. A rare beast with unobtanium NOS static induction transistors from the late 70s. Sony VFET SITS have linear amplification qualities like vacuum tube triodes.

 

I'm building one of these now with one VFET per channel, so I'm a believer.

 

One day left in the auction!

If I didn't already have 2 of these kits , I'd bid!

 

Jabbr -- two kits! Let us know how they work out for ya...

 

For others who may be interested -- Nelson Pass in conjunction with heroic volunteers at Diyaudio put together VFET kits. There is a fire-hose of information in this thread: Sony VFET Amplifier Part 2 - diyAudio

I have a small collection of SIT transistors from Sony as well as a couple of old amps that can be refurbished, as well as a somewhat larger collection of Semisouth R100,R085 and even some of the newer SiC devices ... so enough to keep me occupied for the forseeable future... :shrug:
