Hi everyone !
I have the project of building a hifi amp out of scrap. So I took the famous P3A as a good choice. Unfortunatly I don't have the possibility of making PCBs... and using vero is so much fun and cheaper !
Hence today I present to you the first version of it. Behold !
This is the first time I try to populate a vero board by myself, so many dumb mistakes are to be found - hopefully not too many. The reason I decided to do this myself is simply that I didn't manage to lazily find the plan online... Why ? Is this moronic not to do it on a PCB ? Or maybe I didn't search enough.
So I basically tried to follow Rod's schematic. I noticed on pictures that his own PCB ties Q1 & Q2 together, also Q9 & Q6, which I did too. Rod's the boss, I'm the rookie. VR1 still remains at its symbolic state because I don't have the measurement of the trimpot I would use. Honnestly I don't know how to deal with it. I wish I could put it someway on the "big pieces card" near the fuses.
And that's pretty all I have to say about it for now. So if you think that this project worth the time a bit, I would gladly discuss it with you. Also please consider that I'm not used of posting on forums. I'm more the reader type... so if anything seems wrong in this post, please receive my humble apologies.
Regards,

Sure it is doable....see Shaan's vero board build of another Rod Elliott project -
Death of Zen 15 watt Power Amplifier

Good God, man, Rod's board is only $26! Is the headache of doing a vero board REALLY worth it to save that little an amount? Plus, by buying his board, you'd be helping to support one of the greatest DIY gurus we have!
Even better: I can send you stuffed PCBs as I have a pair that I built but never finished. Send me a PM if you want them.
+1. He is a nice guy which explains stuff very well. BTW no VERO board can match a real purpose designed PCB.

Hey guys,
Thanks Quadtech, I'll check how Shaan gets along with his DoZ. The few I've seen looks pretty neat !
Dotneck, of course I totally get your point. But the delivery of a PCB from Australia is expensive (same price as the PCB itself) and does not match with the spirit of my project. Indeed the big idea is to build this amp from a 3,5€ vero board and scrap from old broken devices. Plus, I've allready begun my headaches sessions, which are one of the many pleasures of diy electronics IMO 😉
If I manage to bring this project to life, I'll gladly make a donation to the Guru. I didn't think of it to be honest, but you are totally right about supporting such a good source of electronic wisdom.
So Jean Paul, I greatly appreciate your offer and I would love to receive your unfinished P3A. Because like I said, I'm positively lazy and I believe in recycling. But I still would like to test this schematic on a vero... So, when you say that "no vero can match a real puprpose designed PCB" what do you mean exactly ? I'm quite new on this forum, but so far I can see, this Shaan guy made quite a nice amp on his vero...
If the fact of making the P3A on a vero is technically pointless, I suppose that I'll try to make it on diy PCB - yes this is my way of life. But if it's doable like says Quadtech (may him be correct) I'd like to perhaps get help from interested people to find out if any mistakes remain... Again, this is my first time making such a complex schematic with this technique, which can be awfully tricky...
Thanks, I'll let you know my progression !!!
