Circuit, help me please

dinorhino · #1 12-04-2007, 08:05 PM

Hello, I've a Diagram of a yamaha TRB 5P, prima series, I'm wondering if anyone who knows or someone who is an expert of electronic stuff, could give me a hand to draw the Printed Circuit Board, If some one could do it, I'll appreciate it. thanks

This is the Scheme/Diagram, pic

And this is the component list, pic

Thanks

It seems fairly simple, why not just put it on some stripboard or matrix board?

yeah! I've tried on Multisim Utilboard, but, the problem is that I couldn't make a diagram, and I can't import to the program 'cause is an image, but I'll try your tip, thanks.

In the manuals for all of yamaha's basses, the print of the exact board that is inside, both sides, is right there.

I'll also save you the time, unless you have those pickups, it doesn't sound as good as you think. I've tried.

thanks for the comment but the manual of the old TRB's does not include the print of the exact board, that's the point that I need the help jejej.

And about the pickup issue, yes I bougth on ebay the single coils, from a TRB-4P.

I hope someone can help me.

If the opamps are TL062's, it's never going to sound good anyway.

+1. no point in getting a pcb layout done when you can mock up this circuit on perf board.

not to mention the shear amount of time and effort it takes to make a circuit layout from a schematic.

That's where some software comes in handy. . . . autoplacement of components and autorouting to populate a circuit board.

well, first you have to learn how to use the software - both schematic and layout. Depending on the software you may have to create footprints for the parts.

Then you either have to but all the stuff necessary to prototype your layout or pay to have a quick turn house manufacture the board for you.

...it's just easier, cheaper and quicker to get the parts and perf board.

I agree. If you only need one or two boards, perf is the way to go. not expensive, and easy to prototype a circuit.

You could try adapting the ESP Universal Preamp/Mixer (Project 94) to your purposes. It's a tidy little circuit board, and not too expensive either.

Otherwise, learn the ExpressPCB software or something similar yourself and have at it.

PCB: yuk.
I almost never use them unless I'm using someone else's design and they supply the gerbers or it's an RF project (bben a while) or a commercial profuct, but I don't do them any more. I can have most audio ccts built warm and being tested before the PCB design will be finished.

I've never heard a Yamaha with good electronics, and that includes the pickups.

The wood working is good though.

I agree. I make these on a regular basis and it doesn't take long at all. I may be going to PCB soon, just because it looks better.

I'm with you there. I've had ExpressPCB on my 'puter for at least 6 months, but have barely ever even opened the app up yet.

I have used Protel a few years ago, but recently acquired Promethius and it is great. lay out a schematic, click the export button and components will be auto-placed on the ckt bd (to your dims), and then it will automatically rout the circuits. Protel does that too, but I like promethius due to the mixed mode simulation capability. Of course, like you, I rarely use it for simple stuff anyway.

DavidRavenMoon · #17 12-07-2007, 12:29 PM

I've been learning DesignWorks and Osmond. I have Eagle as well.

So far it's quicker to use perf board.

dinorhino · #18 12-07-2007, 07:09 PM

yes, I've tried the Express PCB, but that circuit have paths and pins on both sides of the board, I've already tried Multisim Utilboard but doesn't recognize all of the components of the schematic, later the Orcad but it's too difficult to use well I didn't understand it, well I'll been expecting for more helpful comments

jackson_bass · #19 12-08-2007, 07:01 AM

Sorry guys, just in case anyone decided to look for the software that I mentioned it should have been named "Proteus". I was typing that from work and I didn't remember the name of it.
P.S. you can tell the software to use a single-sided board to get away from the paths on both sides issue.

Thanks! I did throw a few minutes at looking for Prometheus with no joy...
