I also made 2 pairs output with source resistor (or jumper if not need)...
I'm waiting your new version...
I have my own layout but the parts are not yet complete (on their way)
I'm waiting the parts (vertical mounted 5 watt resistor) so it is fit nicely at the PeeCeeBee
ps : I feel sorry for my earlier post, hope you don't mind
Hi Shaan, I'm 27 🙂
No, you not the only one.

Assuming we are, this is how the mt-POT version's front-side will be.
I think it's best to make two versions, one for cheap single turn and another for multiturn. No space for adding both in one.
Shaan, there is top adjust version with same footprint as side adjust

Of course not. But what I meant in that post is that initially I planned to make two layouts, one for single turn pots and another for multiturn, and that now I will post only one. That's it.
I have seen your layout, it's cool.

It's prefect Shaan!! 🙂🙂🙂
Thanks
The Renesas parts I have measure consistent in thickness, 4.8~4.85 mm.
The BD139/140, not so much, but mostly around 2.5~2.55 mm
(TO-126 w. heatsink pkg)
The BD139-16S-16/140-16S are between 3.25 and 3.30 mm
(those are all-plastic, so different pkg spec)
KSA1381/KSC3503, also plastic, same 3.25 ~~ 3.30
My mica washers measure 0.1 mm, and my silpads, 0.32
just for comparison....
LC used the Alfets, 5.02-5.03 mm with an insulator 0.33 thick
KSA1381/KSC3503 plastic pkg, about 3.25 mm (no insulator required)
and 2 mm spacers
@Shaan, still planning to respond to the layout, been a bit busy, sorry
One can use two spacers if one isn't enough, simple.
Alright, the pdfs will be posted here once Pete gives it a 'go'.
That said, the pdfs for the current layout is ready. So if anyone wants them, just send me a PM with your email address. Easy.
Cheers.

Shaan,
I think it is a very nice and clean layout, and it places the dual mosfets and VAS transistors very well now.
The 470R which was in paralel w the two diodes is absent, so I assume you are planning on a fixed voltage spread. I would not have a problem with that, but it may be worth noting for other people.
The diameter of the largest electrolytic is 16-mm (?)
That's all from me,
Pete

Sure, I do not see a big issue, but since I have a bunch of parts sitting here, I thought I would post some dimensions, so we can all plan ahead.

Hi Shaan,
Do you have the official BOM for this double MOSFet PeeCeeBee V2 Amplifier?
Btw, given the lengthy threads, how did you implement this for a subwoofer amp?
Thanks again for the nice PCB design.

Now PeeCeeBee has the option to run on higher voltage, say 50V. This is in fact as using double die Latfets but much cheaper as double die Latfets cost 10 Euros each. Also the cooling will be better than single double die Latfet.
No doubt that the builders will have fun!
My pleasure.
I haven't built the dual FET PCB yet. But I intend to drive it with ESP subwoofer processor.
Correct.
Hi Evette.
You can ask guys in this thread who have built it successfully and are close to your residence, through PM. The dual FET PCB hasn't yet been built by any.
Or, if you are in a hurry, then how about etching it yourself and show it off here, will be great.

Important: Non-critical error in Silcscreen of Dual FET PEECEEBEE V2
The 10R and 470R resistors at the positive VAS got swapepd. Apologies. I'm still a fresher in this field. 😱
Please note:- The devices will not fail if someone places them in swapped positions following the faulty silkscreen.
What will happen:- The VAS and Output stage simply will not turn on, there will be no danger for the circuit or speaker(if connected).
The corrected silkscreen is in the next post.
