Eyett fiberboard vs turret boards - BYO vs. Weber

[chuckulaa]

xtian, that looks like a nice build. Looks like you added some features to the circuit.

Yea, again, I am going back and fourth.

I want to just use the fiber board, but i'm trying to be patient and do the right thing. I'm thinking I may try to make a G-10 board with turrets and eyelets so that I can avoid the jacks hitting the board.

Hi Chuck,

You may want to check into some shorter spacers for the circuit board if it is too near the input jacks.

You will learn a lot during your build and if you are they type that learns as you go by your mistakes or triumphs, you will succeed.

Maybe a good alternative would be to coat the board in some kind of sealer.
What that would be, I'm not sure.
Noting real flammable like lacquer.
But maybe some poly coating.

Those large Spragues will require wider spacing of the eyelets of course.

Best course is to draw a scale template of the board and check the components to it to make sure everything fits, according to lead lengths and component size.

The thing I don't care for on that Hoffman board, and I hope he doesn't get miffed at me, but I don't like to see bare wires passing under other bare wires or components.
I didn't study it real carefully but if it were me, I would put some sheathing or shrink tubing on those leads that pass each other.

How come nobody has mentioned tubedepot as a source for turret building materials?

They seem cheaper than turretboards.com, although they only offer G-10 board with 3" width. That should be fine right?

Any reason not to use tubedepot?

Heresnthis haven't used one so I don't know

Well they's in Memphis

I have bought a lot of items from Tube Depot. Have never had a problem with them. Their board is actually 3 1/8 " by what ever length you want up to what they can ship. They have their natural color board on sale right now for 0.45 per inch. don't think they sell eyelets.re: the black boards..some have had problems with the black material being conductive,(so I hear)

Two comments.

I have had black fiberboard from Mojo go conductive and bite me in the ass hard on a AB763 build. Had to rebuild the entire thing on G10. It's quiet as a mouse now, but Never Again.

I have also bumped the input jacks against the turrets on a 5E3 kit build. And I can tell you that there is enough room in that chassis to move the board south 1/8" and everything will fit just fine. It was inconvenient, but once I drilled new holes in the chassis to mount the turret board all was good.

[chuckulaa]

There is also Hoffman amplifiers.

they seem to be the best, and most well rounded supplier of everything one may need.

they sell a pre-drilled 5E3 board for 12$. Granted, I'd like to drill my own to accommodate large coupling capacitors, but 12$ is very reasonable.

they also sell eyelets and turrets, one could maybe a turret/eyelet hybrid with their supplies, and you also get the neat looking Hoffman 5E3 layout.

I'll have to figure this out by the end of the week, because I am itching to get soldering on my amplifier.

I bought a bunch of that board from TD last month when it was on sale for supercheap. It works just fine. Grab their staking too while you are at it. Nothing wrong with collecting boards, eyelets, turrets, pre made, roll your own, etc. that's the only way to figure out what you like, and you will use it all one day anyway . Yep the TD precut is wider than most boards one would use so here's what I did :

Smokebreak, that looks nice.

You using orange drops... 715s?

I have used them before, but the options for widths and length are limited. Also, the checkout does not allow mulitiple quantities of the same board color. For example, if I wanted two red 3.125 x 6 boards, checkout sums it as 12 inches. If you only need a 3.125 width board with a length on whole or half sizes they a fine.

On the other hand, Ken will cut boards to any excact size I desire.

I guess if you did that first, it might prevent moisture absorption; kind of what Fender tried coating every damn thing in wax. But what about boards that already gone silly?

I've been experimenting with Minwax Wood Hardener, which is designed to dry, seal and harden rotted wood. Drives out moisture and fills the material with resin. Seems to help, BUT is astonishingly flammable and you don't want to breathe it, so we're not recommending it just yet. It also may not be a cure since there's been a lot of materials science research on conductivity in "insulators" that have carbon in them and it appears that a high enough voltage differential will eventually change the dielectric properties and establish a permanent current path. Bummer.

In The Soul of Tone the process of waxing the boards-ever so California, right?-is done by immersing the boards in a vessel with molten wax and then pulling a vacuum that pulls all the air out of the boards, which is then replaced by wax.

Sounds plausible. But the boards should have no carbon in them to begin with (fatal error with Fender vulcanized fish paper). Current is like a good sports team; it will find a way.
