Electronics Engineering Major, Multisim

[soloist4hire]

Hey everyone, Im currently working on my electronics engineering degree, and learning a ton. Unfortunatly though, we cover nothing about vacuum tubes. I can pretty much piece all the info together, so thats not my problem, but i was having trouble looking at a schematic and figuring out how to arrange the components on the board. How do you know how to layout your components on your board based on the schematic? Im sure we will get to that eventually, but we are focusing rightnow mainly on troubleshooting and replacing parts... Second question.... I am using multisim to design my circuits, but it doesnt offer any tube components to put into your circuit. Does anyone know of a free program that lets you design circuits, with things such as tube sockets, heaters, and so fourth? Thanks for your help everyone!!!!

I believe Multisim 10 does as well as the earlier ones. It is under misc.

Here was the process used by an experienced builder– obviously not me

Hey everyone, thanks for your help thus far. I read through that document, and got a little bit clearer of an understanding. Is there anyone that might do a picture tutorial of a really simple circuit, or maybe like 1 stage of a circuit? That way I can reference it to my build? Thanks everyone, your all amazing!

Wow....Thank you very much....I am using multisim 10, and couldnt find it for the life of me! lol. You just made my day! haha. This has got to be by far the most amazing website in the world. Allynmey= My hero! lol Thanks again!

Check out the first Fender Champ ampm the 5c1.
Probably one of the simplest schematics out.

How do you get multisim on the cheap? Pro version is beyond what I'd need, use, or want to pay.

I've used TINA in the past for stompboxes, but it doesn't do tubes well.

Best way is to look at many existing layouts and their schemes. This way you can learn from osmosis. Some are point-to-point, some are boards and some are PCB and all combos of the above. Also learn some of the “verbal rules” from reading (e.g. cross wires at 90degrees instead of parallel when possible, mount grid stoppers on the pin, etc.) I still cannot layout a board merely from a scheme and have used only PTP for my builds.

I don't know all the capabilities of Multisim, but it would be really cool if you can enter the Trainwreck schematics into Multisim. Then run a simulation and see how the amp behaves. See how the amps freq response, gain, distortion characteristic, tone stack behavior etc (kinda like how Richard Kuehnel did his analysis on his Bassman book)... I think everyone in this forum will learn a lot from it.

Wow- that would be killer...... I could certainly use this as tool to record mod values to voice the amp....

I too would like to see where a reasonable version of this might be available....
