Identifying something on Crate GX15R Circuitboard

[Enzo]

That is the one I have. He has a 0.1 ohm power resistor, while our drawing has ten 1 ohm resistors in parallel for the speaker return. I interpret that as a 0.1 ohm, his revision just has the one resistor for it.

Let me hint one more time that it would be helpful to have the schematic posted, since mine is not for your revision.

g1,
I checked and mine is a revision 5 circuitboard. I am a novice DIY troubleshooter that doesn't own a smart phone or any fancy computer scanning devices. Nevertheless, the ceramic resistor is very different from all the others and when I Ohmmed it out, I showed 0.0 on the DCV.

Yes Enzo,
I have very limited technical support. No smart phone, scanner, or camera.

What form is your schematic in? Most of us get them online somewhere so they are already in electronic form, which you can just post here.

[jagora]

Enzo,
I don't have a schematic of my own, I was hoping this forum had something and they did except for a minor problem. My computer operating system will not convert into a printable PDF file.

So you are not looking at any diagrams?

[The Dude]

If you found the schematic here, just post a link to it. We don't necessarily need the file itself posted.

He was just calling out the resistor as he saw it on the circuit board, not from a schematic.

the ceramic resistor is very different from all the others and when I Ohmmed it out, I showed 0.0 on the DCV.

You should be on the ohms range, not DCV. It should measure around 0 ohms.

Here is the schematic I have, it includes the "R" model.
I assumed the same as Enzo, that the .1 ohm power resistor is used instead of the ten paralleled 1 ohm resistors in the lower right of the drawing.

[jagora]

No Sir, Just looking at what I see on the Circuit Board

Hey Dude,
I see you remember me from my difficult time when, I was trying to print the diagram?

g1,
Does it matter where I set the dial indicator on the Ohm's range? The setting options are: 200, 2000, 20k, 200k, & 2000k

I see the schematic and back traced the Speaker Out Put leads. In my case, there isn't an actual Speaker Out Jack, it's simply a red & black wire..

This resistor should be measured on the 200 ohm range (because it is less than 200 ohms).

So on the front panel of the amp, there is only the input jack and the headphones jack, but no other jacks?

I had no idea they were this valuable...
