turretts and eyelets

[jim]

I am building Sluckeys AC-15 board. It is very complex.  I cant seem to get more than two components wires into the turret.  It is especially difficult when an under board jumper is hooked over the top.  Should I wrap the additional components or parallel solder to adjacent leads?  I have made eyelet boards and this is never a problem.  Its a basic question but I need to know before I solder.  Thanks Jim

I believe Sluckey used 1/4w R, IIRC maybe 4 or 5 leads per turret 

[sluckey]

That's why I use 1/2w metal film resistors. I can easily fit 4 leads in one turret. I also use 22awg jumpers. You'll find that all my later layouts are arranged based on using skinny leads.

Well I have plenty of carbon comp resistors with extra long and fat leads.  Ill tack em in the best I can.  Jim

This is where eyelets work way better if you are trying to stuff many leads into a terminal

Do jumpers and hookup wires around the base of the lugs
I do under the board jumpers into the under side of the lugs

In my board build instructions, there are some pics of how I like to wire boards

Exuse me for the hijack

Just to have confirm

the little ones on this board are 1/2W metal film resistors ?



Thanks

Yes, the ones Hoffman and AES sell.

Probably yes.

But it is getting hard to tell. Resistor sizes for power used to be pretty standard. But modern resistors use higher temperature material and may be rated for higher power in small size. I have seen what I thought were 1/2W parts carrying a 3W rating (they must glow dull red at that power).

[sluckey]

It is getting hard to tell. You sure can't go by size when looking at different types of resistors. Look at the two black resistors just below the Atoms bias caps in this pic. They are rated 1Ω, 1%, 1W. About the size of a 1N4007 diode.

That's right, it's hard to say, that's why I asked by showing a board by Steve

he told (post #2)

That's why I use 1/2w metal film resistors.

So the point is if one is using many fat lead  components like cc resistors and orange drops rather than metal film resistors, Mallory or Xicon caps then eyelet construction should be specified rather than turret.Jim

Or, if you're laying out the board from scratch and it's not super cramped, then just use more turrets and jumper them together. Often looks neater that way too.

Look, for example, at Sluckey's AC15 layout http://sluckeyamps.com/VAC15/ac15.htm. There are a lot of components on that board, but Steve laid it out so that most of the components are parallel, generally no more than two leads per turret, but used a lot of jumpers. The alternative would have been to have many components going in all different directions in order to minimize he number of turrets. I think it looks better the way Steve did it.
