Turrets vs Eyelets

[surfsup]

Is there a specific advantage to turrets rather than eyelets? they seem easier access at least.

Also, I can see that Michael's crafts sells em for 100 at $2 (eyelets), the amp supply houses are charging 5 times more, and the turrets are $0.22 each. That's $1 for 5. I work with CNC shops and this is really steep. Is there a less expensive source? The turrets alone would be $30-40 for an amp for the casual builder.

I've always bought eyelets from Hoffman Amps, they also have a much better deal on turrets then what you're quoting. Not sure what the Micheal's eyelets are made of and whetther they'd be the best option for your work. Mouser is another source you should check for eyelets and turrets.

I second Hoffman's turrets. Just got some in the mail yesterday. Hoffman is cheaper than 22 cents, for sure. Plus, his are chamfered on top. Makes it easier to insert components.

It depends on how many you want to buy. If jut a few then Doug's make sense. If you are going to be building a lot then buy them from the same place that Doug does.

Personally, I would rather use turrets that eyelets. I find that changes, repairs and component placements are easier. If there are any cons, I think they are harder to install and of course cost more than eyelets. I get my large double turrents from Watts Tube Audio. Now Mouser carries that same turret, but you don't really get a good price break unless the quanity is way huge. I've also used other Keystone turrets that I have purchased from Mouser as well.

Applicable eyelets are cheap, a nickel a unit from Mouser when purchased in quanties of 100, larger quanties are even better. Therefore, why would I use a craft eyelet and contaminate a solder joint with paint, plastic and other chemicals just to save a few pennies.

I found that eyelets would not let me stick-in as many leads into the same turret. Like, the phase inverter for example: four components into one connection point....no room in that turret for all the wires. So, I like eyelets better. I am just a beginner at building amps FYI.

I've used both extensively. Turrets are good for some builds, especially Hiwatts (mandatory!) and also prototypes as it's easier to change parts out.

Lately I've been building Dumbles, and used eyelets. Turretboards use up way more space if you stick to the parallel compnents '50s military style. Do not use turretboards in tweed chassis! You will quickly run out of space. Ask me how I know.

Currently roughing out on paper a Martin 112T circuit with an extra pair of 6V6. It is going in a Weber high power tweed twin chassis.

The circuit is an interesting take on a 5E3 that was made around 1960 by DeArmond & Rowe for Martin durin Martin's foray into electrics at that time. Much bigger iron than typical 5E3.

That will be using a Watts 5E3 eyelet board. Which is not the way D&R did it. They actually used little eyelet boards with the parts gooped in thin epoxy! Almost twenty years before Dumble did it. One for preamp/PI, one for tremelo etc. See pic below.

I looked, but couldn't find them at my local Michael's. I asked for help too. Where are they supposed to be -- near what other stuff?

Yes, it's nearly impossible to stick more than two leads into the average turret hole. There are large turrets available, but the beauty of using turrets is that you can also wrap leads around them. You could expect to connect up to 5 or 6 components to a single turret if you had to.

I've never had any trouble getting four even five leads through a regular sized eyelet.

Here's Mouser's current catalog pages for Keystone eyelets and turrets.

The eyelets at michaels are brass, unfinished. I don't see why these wouldn't work, there's no paint, etc on them or anything.

The eyelet bouard supplied with the kit from ax84 worked well for my HO build, and on some I got 5 leads in there but it was tight. With 5 redoing stuff was a hassle but it was ok. With turrets I can see a problem with unwrapping leads on top of other leads when you have 5 on there, or more.

I'll check mouser, etc. Anyone use the michael's eyelets? These seem by far the most economical.
