Need advice on this configuration

[CitizenCain]

Can someone tell me if these two are functionally equivalent?

When laying out the filter board for my amp project, I noticed that I have the parallel resistors for two of the 80mFD caps placed on the other side of the cap compared to the schematic. Is there going to be a problem with the resistor being placed between the 1K/10W cement and the pos cap lead?

What I'm wondering is did I accidentally create a voltage divider that's going to affect the reading at the + lead of the filter cap?

As designed:

Did I screw up?

Lookin' for a little help.

If I understand the question, the answer is yes they are equivalent.

The schematic is not a layout diagram. It is not meant to show where components are located in relation to each other. It merely shows electrical connections. If 3 components are connected by a line on a schematic it only means they are connected to each other by some conductive material. There is no hint as to where the components are located or how they are connected together (although there are exceptions: for example shielded cable but that is actually a functional part of the circuit)

Thank you! Yes, I understand the schematic is not a layout, but I second-guessed myself into confusion when I read about voltage dividers and realized that the layout I created looked like the example I saw.

You can tell I'm new at this.

Thanks for easing my mind :D

I usually mount power resistors away from the circuit board and other components that would be affected by their heat. But given the temperature ratings of newer electrolytics I concede it isn't normally a problem.

CitizenCain (http://www.thegearpage.net/board/member.php?u=2911), In looking at the layout it seems there is something you should be aware of. It is generally good practice not to rely on the PVC sleeve of standard aluminum electrolytic caps for insulation. In other words, it is best not to let other metal come in contact with the caps. The exception are caps designed to be held in with clamps (as opposed to those only held in place by their leads). The clamped type have additional insulation compared to most self supporting caps. I know many people do not follow this practice, but it is followed by most manufacturers of high quality electron gear.

http://www.chemi-con.com/guide/pg5_ms.php states it clearly:

"2. The outer sleeve of a standard capacitor, made of polyvinylchloride or similar material, covers the aluminum can and is used only for marking. This sleeve is not designed for insulation purposes."

Looks like I have a couple of reasons to rebuild the filter board. I'm going to fire it up like this just to see if it even works, but I believe I'll be redoing the filter board soon.

Thanks for the heads-up, antik.
