Srajan has the 1st SIT amp for Une dégustation

[Zen Mod]

The R100 is on the top, red cable +voltage, and the SIT is in the lower part, input cable....look at the picture.

I saw that , but just couldn't resist ....

 

[generg]

Of course you saw it.....

It was a hint for teabag

 

[Zen Mod]

hehe

whatever , Tea can't be dumber than Mighty ZM

 

[CeeVee]

..It's like making a F1 street-legal.

This is going to be some ride !!!

 

[Zen Mod]

yeah ....... SIT Zen amp with front knob adjustable bias ;

also - evaluating all that with Funky Tannoys ; each member of chosen evaluating team have identical set of Tannoys in Jensen Imperial cabs .....

who said that developing hi-end gadgets can't be fun

 

[Tea-Bag]

hehe

whatever , Tea can't be dumber than Mighty ZM

I think I am, and that keeps me out of some trouble.
But I don't beat myself up over it. Acceptance.

 

[generg]

hi tea-bag,

happy to hear from you...... and happy to hear you prefer the Lowther Alnico over the DX, that saves some money for me.

so we could try to drive our working Mu followers without j-fet fronted..... only for pleasure!

 

[Tea-Bag]

I didn't see optocoupler in SIT amp.....

Not a bad idea generg.

 

[Nelson Pass]

yeah ....... SIT Zen amp with front knob adjustable bias ;

Mike Rothacher has previously reported that his design has that also.

 

[Michael Rothacher]

Indeed.

I promise the article really does exist. In fact, there are two.

They are both in the capable hands of an illustrious and intrepid publisher even now.




P.S. I like the cliffhanger prototype reviews. They're fun.

Nelson,
Do you have an extended output graph for the R085. I am going to put it into a Zen style amp this weekend to try to get a feel for sound at different bias points.

 

[Nelson Pass]

Do you mean thd vs output? The existing graphics pretty much show
it clipping above 10 watts. The characteristic curves put out by SS
are not particularly helpful in this regard as they only address the
linear region up to about 6 volts.

I suggest that you set an arbitrary bias current and adjust Vds bias point
and either measure or take a listen.

Alternatively you can set an arbitrary Vds and adjust the bias...

 

[buzzforb]

I was talking about the output characteristics graph that only goes to 6V. I was going to try the whole load-line thing, but I will do as you suggest. Question. Is the thing that makes the SIT special, the fact that it has no saturation point, operating in the linear region throughout its available range or is it the concave shape of the response curves.

 

[Michael Rothacher]

I just saw a couple new paragraphs were added.

That absolute polarity observation is no joke. I'm a believer.

The SITs are spoiling me. There's really no going back.

 

[OllBoll]

Michael, might one get you to drop hints on what kind of sound signature the amp you're publishing has?

 

[Michael Rothacher]

To borrow a phrase from the vdeo game generation:

'It's like a unicorn crapped a rainbow in my brain.'

 

[Michael Rothacher]

Sorry, I couldn't resist.

Self-review is kind of a slippery slope, but it's a fair question. I think they have remarkable clarity and really nice, vivid soundstaging. The more I listen to them, the more I like them. An idealized triode, without the tube baggage springs to mind. That's all I can preview now. The rest is in the article.

It's all speculation on my part, but I imagine the FW amps must sound pretty freaking awesome.

always ;

all of them .

You'll soon know first hand, lucky boy.

Listen before and after Slivovitz for compare and contrast.

 

[Zen Mod]

naah ....

better some glowing thing , surrounded with plenty of iron ....

ironless amp are for sissies

( NB that I don't need Schnaps to be wakoo ; comparable with Asterix )
