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.
I quit long before I clip the amp. My JBL's are rated at 150W RMS and I don't intend to wreck them just so I can impress someone. The Gnome clipped at 40V/8R on only +-57V rails. Imagine what it will do at the +-72V I usually use.
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.

Nice jwilhelm,
Now just take out the connectors and add the power amp section to it for a single board design, 2 pair, 3, 4, 5. All you do is add the extra output device sections you want.

I've got a theory on how to do that. You just chop the board off at the number of outputs you want. Fuses would be where they belong, no the supply and the output inductor at the speaker binding posts.
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 🙂

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.

Don't worry PCBWay is cheep😉
As you can do it home etching friendly, just do it as an alternative version.
