While they last...

Super curves quartet! It's look like THF-51S correct ?
Yes, they are!
I think it is a new pandemia, caused by Papa and you!
Tomo is a super-spreader!
I've contracted by this virus, there are more mutants on the way, like four roughly matched one, four roughly matched 2SK180s, and four 2SK182 or 182ES, I don't know yet, because these are "new original" chinese mutants.

"I have not found that much difference between them for audio use, so no big reason to get excited."

I think that the "Excitement" ship has left the dock, the boat careering from side to side, like a drunken raft in a gale, multiple types of music blearing, (though all of reasonable quality considering the circumstances), some people completive, weeping into their drinks, over age normally stern men waving their arms and "Dad dancing", for others it is just too much, they have leapt overboard unable to cope, (luckily the water is only waist deep) as if attacked by gently stinging bees. Those left behind at the dock wailing, wondering if they will ever get a ride on that boat, "Ears of ecstasy" their loved ones trying in vain, to console them..."Don't worry dear, you can build a hot rod instead"... All the while that guy is hoping to steal a rowboat and catch up.

"no big reason to get excited." He said!..........
 
You have said nicely, I like it.
In any case I'm on the boat.

"I have not found that much difference between them for audio use, so no big reason to get excited."

But people are able to spend a lot more money on say all kinds of cables, capacitors.
And they get excited, have knife-to-knife debates about which is better.
Papa said somewhere, most depends on the active components.
Now he comforts only.
 
Package arrived from Pras today. Like the GT3 I want one day, used with proven track mileage, and many more miles to go.

Twitchie - that's a beauty!!! that looks like possibly fake, or maybe real track dreck on the gulf livery. Excellent. I keep track crud on my car for months. Lazy? badge of honor? My 997S is still hibernating for winter. She'll be out soon enough, and hopefully on track this year. Melted snow and sun in the sky is making me anxious.
 
What's the difference between the THF-51N and S version ?

I don't have any special THF-51N datasheet but from Tokin papers
they are inside of the THF " family " with 50, 51, 52, and 53 numbers.
Gate to drain maximum voltages is differents 450~1000V and Drain to Source ON resistances
can vary from 0.6 Ohm to 1.2 Ohm maximum.
All models are great for class A 40~ 50 Watt's audio amplifiers
but for DIY plasmatronic ray gun that different story..1000V transistor it's a recommended minimum haha 😉

Do you know the differences between S and N?

Should I assume it's GT3 vs. GT3 RS performance?

N version = No limits of good things :cheerful:

Received today my THF-151S from Tomoaki. Beautifully packed ; matched to perfection and with the insulators/ferule...etc.

Tomo is a real gentleman. I can only recommend this source.

Can't wait for this build and see how this will fare with my Full Range system.

Very cool.
