I'm noticing many people having problems here with Drip V72 and R47 pcb boards. This is partialy due to lack of experiences but also huge pcb (for what it is), having all sorts of solutions which could be a lot simpler and effective. Good build guide and support are also lacking, i haven't check those for years but questions here are still the same. Parts are pretty expensive because of mentioned approach, for example many big and expensive film caps probably after lytics don't make sense ime, if it should be quite simple build.
Making such preamps or other simple gear p2p would be simpler, despite requiring a bit more drilling/cutting and learning groudings which is also needed for pcb. Since documentation isn't good even for pcb, making it p2p might require less hassle and provide knowledge for further projects.
I wouldn't use meters, make Gyraf like psu if beginner as i was 20 years ago when making first p2p (it is class a where diodes, regulators or zeners sound the same without problem associated with tube psu), pads/attenuators could also be simpler while functioning properly, etc.
