Default aleph - any point-to-point builders?

I've noticed that most people use PCBs when building Aleph amps. Is this necessary? I'm more comfortable wiring circuits point-to-point. That's how I built my BOSOZ too.

Is there any sonic difference between a PCB-based aleph and a point-to-point one?

Well for what it's worth, I'm building my A30 point-to-point. It's not difficult at all, but then again I haven't finished yet so...
Will post pictures later.

Have you looked att www.passdiy.com in the gallery section?

Regards

I decided to wire my Alephs point-to-point after seeing these pics in the PassDIY gallery:

Default My Aleph3 p2p picture

It is very simple to make it p2p.

very impressive work but I was referring more to using perfboards.

I most always P2P when prototyping, and I've made a point
(pardon the pun) of comparing the P2P version with the
later PCB version. On a couple of occasions it has revealed
errors in the artwork, but in general I've never notice degradation
going to a PCB board, provided that the layout and board
quality is good.

If you're only building one, the attraction of P2P is obvious, but
when you're in production you're way better off with the
consistency and reliability offered by a well made PC board.

By the way, I only use plated thru holes - I like to solder into
sockets.

After switching to Teflon isolated plugs with MU metal shielding and Teflon isolated wiring i figured i might step over to Teflon PCB's too.
The Teflon boards i make myself, my dad was a great DuPont aficinado.

I think i hear the difference compared to RGF PCB's, same with Pertinax compared to glassfiber, who's to judge.
Repairing is certainly easier with a PCB mount.
But hey, i like the artwork on the picture.

Through-Through soldering will never get you a cold spot and it looks so breathtaking.

Ever tried to debug spaghetti code? Programmers wince when looking at computer programs that use lots of GOTOs and other obscure references. There's a reason for that--it's a nightmare to maintain. Can you write a computer program using spaghetti code? Of course. Will it work? Well, it can be made to. The problem is that adding new functions or fixing a problem is seriously difficult.
Point to point wiring--at least the way solid state people approach it--is the electronic equivalent of spaghetti code. It can work, but you might want to think in terms of whether you'll be able to make modifications or repairs later.
If you feel that you simply must do point to point for solid state gear, take a moment to ponder the layout of a well made piece of tube equipment. It's not about making a three dimensional jigsaw puzzle; it's about making an artistic statement that will be easy to deal with later, should the need arise.

Phew. After having spent the entire day behind my soldering station I finally got on channel of my Aleph30 upp and running. I guess it wasn't as easy as I initially thought it would be. I also found out that my heatsinks were way too small... Or how does 80 celcius at the MOSFET sound to you?

Also had a bit high offset, ~0.6V, probably because I omitted the input cap in my paranoic serch for perfect sound. Well in it goes! By the way, what is considered to be a too high offset voltage?

And lastly on Greys note on spaghetti...
