Slewmaster - CFA vs. VFA "Rumble"

I'm liking the SMD with Diptrace. I don't think Sprint would cut it for this.

I still do my own layouts, autorouters suck at it. But I let the PC verify for me. I get all the hard stuff right but miss the obvious stuff.

We will have to meet some day , brother.

Did you know , me and another COOL canadian brought the toner transfer
method to DIYA in 2007-8. We were drawing with sharpies , then
the toner method infiltrated the forum.
carlos did not know , all of a sudden .. nice PCB's started to appear.
Now we are at the gerber > china > pro level.
A Nice 5 year progression.

I can't remember when I started with TTS. It was in the early days when Pulsar (I can't remember what He called his company first) was just starting to take off. I used their TTS paper and reactive foil for ever. I've worn out two of their laminators. I'm redoing a pick up truck right now that I built in 2001. I pulled the SMD dash out of it on Monday. I forgot I had built it. I designed all of that with Corel Draw. I'm almost as fast with PC board software as I am with Draw now. I still catch myself trying to use Draw's keyboard shortcuts for aligning and distributing components.

we gotta talk on the phone (I'll slow down) again.

This slewmaster "thing" is "out There", it will level any living space. I'm
even quite - amazed. Same as still4given , my OPS is still a household
spectacle ... I can't clip it !

I'm amazed what that sub amp version can do. I never expected one ACI driver could level my office and blow a speaker box apart. I didn't realize how much power it had until the next day when front office staff were asking what the rumbling noise was. I work in a million square foot building. The front offices are at the opposite end of the building with a warehouse and two block firewalls separating us.
 
Can someone let me know the 5 pairs SM OPS size. I was too busy with the mosfet version when the boards was available.
I decided to build the 5 pair transistor version so I can compare it with the mosfet type.
I ordered some clad board to etch my own boards together with the mosfet type by heat transfer method but for that I need to know the size of the actual PC board.
I'm more familiar to use metric as a measurement.
Thank you for your answer.

Please guys someone let me know these PC board size.
I did some work on the layout to be more iron transfer friendly now I lost the right size when I print it out , now I have no clue the correct size.
It can not be so hard someone measure his PC boards and let me know.
Thank you 🙂
Greetings

Kypton-ND easily fits on a 3" x 3" board in SMD. I'm going to see how far I can shrink it without getting too nasty looking. (This is just autorouted and will change quite a bit before it's finished.)

I want one !! 😎

Actually , this is the best of the CFA's to go SMD - everything
is low current with the super-pair VAS.
"current on demand" does not "feed" saturation on this or the K-C.
1-2 ma Q1-8 , super pairs are "ice cold"... just the 5-6ma Q11/12.

PS - Q1-8 could be run as low as 1.2mA with R4-7 , R18-19 changes.
