Moderators Kindness Posted February 8, 2009 Moderators Share Posted February 8, 2009 In preparation for our amp build, I have prepared this short tutorial on reading schematics and layout diagrams. I don't expect it to be very easy for a new builder to use this thread to go from zero to expert, but I do think that looking at the information in this thread, it will help make more sense when you have the diagrams and parts in front of you. Consider this an introduction to help you from feeling overwhelmed when you first sit down with everything in front of you. This is the schematic of the 1959 Fender Bassman (version 5F6-A Link to comment Share on other sites More sharing options...

You're welcome. The FAQ is where good threads go to die, but I'm sure it'll make it there eventually. In any case, I'll keep links to these in my signature for a while and eventually they may be hosted on another site (http://picofarad.info/).

Members solderjunkie Posted February 8, 2009 Members Share Posted February 8, 2009 ooo0OOO0ooohhh.... your amps are so clean inside (they are yours aren't they?). My oldies always look to have been assembled by Leo's acid-trip buddies. Tons of extra wire, {censored} that's crooked, big blobby solders, etc... I dig the "layout" diagrams... always have. They are cued more to the lowly repair tech. The "schematic" diagrams always seemed more of an "explanation of the circuit". Link to comment Share on other sites More sharing options...
Members Pickdust Posted February 8, 2009 Members Share Posted February 8, 2009 Good stuff K! All the toots have been nicely presented and logically thought out. I'm going to be studying this one for a while. Thanks for taking the time mang! PD Link to comment Share on other sites More sharing options...

My oldies always look to have been assembled by Leo's acid-trip buddies. Tons of extra wire, shit that's crooked, big blobby solders, etc... Thanks. They are mine and they are generally clean inside because I built them. Of course, these were my first two a while back so I look at them and think they are a mess inside.

Members Casey4s Posted February 20, 2009 Members Share Posted February 20, 2009 I assume these are both your builds in the photos. Nice neat looking work Just curious why you use eyelet boards, I find turrets a lot easier to work with, trouble shoot and make modifications. I hope everybody's projects go well for them. I'll be watching the thread Link to comment Share on other sites More sharing options...

Members Casey4s Posted February 20, 2009 Members Share Posted February 20, 2009 These weren't just the first two amps I built, they were the first two I'd been inside. My mentor extolled the virtue of eyelets over turrets and it also made sense to use eyelets for Fender designs. My current build is a 100 watt Marshall and it is my first experience with turrets (after spending most of my time in Fenders, Ampegs and the like). You can see it here. Or just see the pictures here. Kool, I am not sure why eyelets are better suited for Fender layouts but whatever works best for you is the important thing, I guess it's just preference. I've used turrets for everything Fenders, Ampeg, Gibson, and a lot of other stuff. Nice looking job so far (in your picture links) this should be a killer when you're done.

I'll get back to it again a little this weekend. Maybe have her fired up next week. There is a big part of me that is delaying the build because I enjoy the process and don't have another one right in front of me when this is done.

You do realize at this point that amp building is habit forming and highly addictive. If it weren't for the $$ I would always have something on hte bench.

Members zoomzilla Posted February 22, 2009 Members Share Posted February 22, 2009 Kindness, that is so cool of you to post this stuff. Ironically, a friend of mine is sending me a Bassman in pieces so it is incredible that you have the bassman layout here. I don't know how to read a schematic, but I sure as heck can read the layout. I will most likely not have all the parts I need, so the layout is priceless to me. Thanks! Link to comment Share on other sites More sharing options...

When it is time to reconstruct the amp, first figure out which Bassman it is and make sure you are looking at the right layout. If you need help figuring out what you have, just let me know.

Cool, I will hit you up when I get the amp. The question is WHEN will I get it. The dude that is sending it to me is pretty reliable, but he might be slow.
