How to create/design a layout from a schematic?

Post by joel_ostrom »

I'd like to build a clone of my Fender Blues Jr., but all I can locate online is a schematic. Some amps have specific layouts that really help with building an amp from scratch, but this one has been hard to find.

Is there some good methods to designing a layout just from a schematic alone?
Anybody ever done this before?

Thanks,
Joel

yes, there is...it's what I do for a living (among other things)..and JazzGuitarGimp (Lou Rossi) as well...among others here....
all we need is the mechanical constraints and your choice of I/O hardon-ware :lol:

You need to understand the topology of the circuit to build a layout.

In this case you can take a traditional fender design/layout and substitute parts. They are all layout out about the same.

That's pretty cool man. How might you recommend to me to go about doing it myself?

I realize that's probably a very broad question, as I assume one needs to have a lot of experience in electronics to do such a thing. But i'm interested in learning.

What's the first thing I should do to learn to translate schematics into layouts?

sigh....take a basic electronics course is your best bet. if you can actually 'read' the schematics and 'see' what is happening electronically....yer halfway there.....like selloutrr recommends....start w/ a known layout and substitute values for starters

With apologies to the OP, this type of question always makes me think of this:

Download a bunch of the classic fender layouts and schematics (the old amps had both). Study them until you understand what's going on. Then, you'll realize that they're all very similar. Take what you have learned and layout your Blues Jr. Of course, at this point in time, you probably will realize that you don't really want to build a Blues Jr. :.)

I just sold mine Fender Blues Jr for $300 going rate and it was in good condition. But there is a non-reverb layout and schematic from Hoffman's forum to go by called Bassman Blues jr. Doesn't use the EL84 power tubes rather 6V6's. Hard to build a amp for less then the price of a used Blues Jr.

I did the "monkey see monkey do" gig with Bill Dunham's Dumble Steel String Singer schematic and just used the Overdrive Special layout, inserting the local negative feedback caps & resistors where necessary. Works fine. See below, I did not put in the reverb.
