Hello....I'm seeking some words of wisdom from you experienced builders.
So far in the 3 amps I have built, I have used fiberboards with eyelets....but, I really like the classy, vintage look of turrets....The Amps I have built with eyelets have been extremely quiet....so my question is....Is there any difference in noise using Turrets vs. Eyelets????

What I like about turrets is you can connect wires through bottom hole below board, wrap around turret post and also through top hole. IMHO you have more connection options with turrets. Plate

I kind of like forks a tad more than turrets. With forks, there's no need to deform the component leads. Just lay them in the slot. And you are generally making a smaller solder joint, applying less heat to the part. (Doesn't really matter, but from my some-tube, some-solid-state background, I like using the least amount of heat possible) True, you cannot feed the terminal from below, but I don't like to do that anyway because I want to be able to readily see all the wires going to the terminal. And if you make a mistake, it's massively easier to desolder the part without bending up the leads. And during troubleshooting, it is much much easier to simply lift one side (or all of) a suspected bad part out of the fork, swap in another one, and test. If you are a believer that component leads have to wrap around the terminal for a better mechanical connection (I am not) they can still do so.

I like eyelets but use turrets for some applications. Turrets take longer to install and cost at least double an eyelet.
Forks... got to have holes. (IMO)

A well designed eyelet board will make a great amp. A well designed Turret board will make a great amp. A well designed PCB will make a great amp. Any of them, poorly designed, will make a poor amp.
I don't know that it really matters which one you use, but it is probably easiest to use something you are familiar with. Or, you could try them all and use the one you like the best. Myself, I like PCB's, but they do take more effort to design, and getting them made professionally (which gets you several quality improvements) can be expensive for larger boards.

The benefit I find with turrets is it is easier to keep your resistors off the board leaving air to circulate. I use a combination of both sometimes as eyelets will give you more room in tight places. Mods seem easier with turrets over fiberboard. Solder is easier to remove to me.

I agree with Gabriel's comments that done well either of those will make a fine sounding amp.
Other than working on a couple of Fender amps with eyelets, I have never built or modded an amp with an eyelet board.
I've always used turret boards, tagstrip boards, or terminals strips of various types. I want something that I can wrap wire around. Just a personal preference.
For parallel layout board designs, the tagstrip boards actually work pretty well IF you don't have to mod them much. They have two tag/eyelets on either side of an eyelet. That allows quite a few options of hooking stuff up. Problem with them is they are quite flimsy and break very easily, in my experience. IF there were some truly sturdy ones, that would probably be my first choice since a parallel board allows such variation in rewiring and modding. However, you can easily build parallel turret boards which is what I use on my more "experimental" builds now.
Never had an issue with turrets or the heavier duty terminal strips.
With respect, Tubenit

Thanks to all of your input....I'm going to try turrets on my next build....I like the look, and it's fun trying something different
