DIY progress report

[Zen Mod]

I like your Mechlabor ;

what are those 15" ?

I presume FR's are Fostex ?

 

[Gyuri]

Yes, I'm also like it.
Papa says would be here Eminence Beta-A 15" for OB.
So there are.
Yes, they are.
And the weakest link?

 

[jacco vermeulen]

your Mechlabor

STM-610.
Dayum, what a tank.

 

[Gyuri]

Yes, this is a nuclear-proof apparatus. Approx. 76 Kg.
Here are a few high-resolution image of this as well:

.....
And the weakest link?

if we exclude short circuit between two headphones - probably missing pair of 15"-ers

 

[Gyuri]

This was not its goal.
Why you are selling your Sonidos?

 

[c2cthomas]

Welllllllll - I found one weak link laying around on the floor. But I'm pretty sure that G is being much more subtle than that.

Second guess - big 300b tubez amp???

 

[Gyuri]

But no! Help, what kind of place I got to!
Well this is here the weak link, right?

 

[c2cthomas]

But no! Help, what kind of place I got to!

Mahahahahaha -

 

[Gyuri]

Of course, I'm probably the weakest link.
So now I'm going to sleep.
All the best, my friends!

Why you are selling your Sonidos?

I wrote already - I need boxes for living room ;

being spoiled last years with big cones ( means foundation ) - I must have them ;
only efficient way to having Sonido FR as main driver + 12" or 15" helper is to put 8" on OB and biggie in any sort of MLTL , which must be folded in two ;

that way I'll have enclosures too deep ........

so - I decided to Sonido-fy recently traded EV12TRXB , which are 12" coax spks (Sonido-fy means - take them for recone to Varga ) and make proper tall MLTL for them , which hopefully doesn't need much deepness ........

so - I just passed Sonido 8" to proper place and I'll be using 12" EV-Sonido coax


speaking of that ..... why you're using Fostex , instead of Sonido - which is local to you ..... ?

 

[Nelson Pass]

Very nice set of OB's.

 

[Vix]

Gyuri,

You deserve a B5!

 

[Tazzz]

I wonder, will we ever see a firstwatt circlotron?

 

[Nelson Pass]

I don't know. Is there some particular reason you prefer a
circlotron?

 

[Vix]

The possibility of having the simplest circlotron which doesn't self-destruct

 

[Melon Head]

Come on Nelson, don't tease everyone.
When are you going to let the cat out of the bag?

 

[Vix]

The whole joy of DIY is making jokes, assumptions having fun. Now we wonder what's Papa's next secret device, or how does it work. Sometimes we guess right, sometimes we miss, but it's fun. It would be just plain boring if Papa would simply put the finished schematics out there; he wants to see us use some grey cells, and not just copy/paste.

 

[Tazzz]

I don't know. Is there some particular reason you prefer a
circlotron?

Seems to me to be a logical step to fold half of an F5 into a circlotron and replace the output fets with Jfets.

circlotron?

Simple, minimul, Zen-Like, even if it's only a follower! The prototype I built drifted around to much? I suppose the real trick is to find gain devices with 0 temperature coefficient, that can operate at a convenient Iq, and having semetrical curves while swinging + and - current.
