Hello again!! My components arrived a while ago, and I am finally ready to refocus attention on this project. Need to know if this is the right component, though, as what I received looks significantly smaller than what galaxiex has in his pics.

This is the 2N5457 transistor. Will it work??

Hope you are all doing well! Also hope I get this finished this year. Lol.

Thanks, as always!!

Hi Everyone! Just wanted to let you know that I finally ordered the two missing components...they should be here soon, and then I'll be ready to get back on track with this project.  :)

I just got majorly confused...please clarify.  I bought the .047uF Caps.  They look like the ones galaxiex used in his build (2 caps with large green tops).  I also bought another package of 0.047uF caps that look completely different.  They are much smaller and have an orange top.   The only difference is one is Polyester-Film and the other is Ceramic-Disc.  According to the specs, either type is fine.  Are these both the same? They look so different.

I still am having trouble getting my hands on the transistor I need and I keep buying the wrong cap...I *think* I am missing the .1uF cap at this point.  I will try to exchange what I bought tomorrow.  I am also confused that the plans list all of the components, but say nothing about a speaker.  What kind of speaker am I looking for? How big/powerful, and will it have some kind of hookup ports attached to it?

Thanks!
Thanks!

At some point, I would love to understand how you decide what goes where on the board and why.  Just throwing that out there because it's on my mind...right now, my brain is too full with trying to figure out how to build this without trying to understand the whys of it, too.  But it's something I wonder as I stare at the schematics.  :) 

Roly: Is it possible to do a schematic of the underside of the board, or is that a silly request? Galaxiex:  When you take your pics, can you take one of the underside?  I don't know why, but I feel it might help me.   :)

Can someone tell me if the second item in this pic is one of my missing components?  Thanks!

Sorry it's a little dark...I can't find my camera and have to use my iPhone. :/

OK.  So, I placed all of my components into the CORRECT side of the circuit board  :loco and would like you to look it over to make sure C2 and C5 are in the right places.  I am still missing Q1 and C3, but I did get the pot I ordered in the mail. (That sounds wrong.  LOL).  If it's all in the right places, do I have to test something to make sure they work, or do I have to wait until I get the missing components?  I bought a multimeter and wire strippers, but I am waiting for galaxiex to post pics of the next steps so I know what to do with the wires.   ;)

Seriously, those pictures are SO helpful.   <3)  What I started to do to create a system that really works for me (and I think will help in the future) is to record things in a notebook with the "coordinates" of where things go.  So, for example, "C1: 6B-6D" will help me put things together again without looking at pictures.

Hope I'm on the right track!  I will mark the spaces like galaxiex did once I get the stamp of approval that it's all in the right place.  Thanks!!

I am!  Sorry I've been MIA.  Life got busy suddenly with a sudden burst of motivation to do some work on our house.  :)  Would love to have this completed by Oct. 14 (anniversary), so I'll be working on this again soon! Have you started soldering?

Not sure if you already addressed this, but does it matter which side of the board I work on?  galaxiex is on the non-copper side, I noticed in the pics.

In any case, it will go on its side horizontally between "i" and "j", +ve to the right, somewhere between the two vertical red wires.  Its -ve end to "i3" (your i5) and the +ve end to the +ve rail "j" wherever looks good, say around your j10-12 depending on its length.


Can leads from two different components overlap?  C2 is slightly overlapping R2 on my board right now.

Also, where does my axial C5 go (specifically)?

Just wanted to share my new tool...my Helping Hand arrived today! I am unnaturally excited about it. Lol

Both Caps I have look the same (except for size).

I can't figure out the quote feature...it just takes the whole post and won't let me select a small portion. LOL. 

Roly said: "In any case, it will go on its side horizontally between "i" and "j", +ve to the right, somewhere between the two vertical red wires.  Its -ve end to "i3" (your i5) and the +ve end to the +ve rail "j" wherever looks good, say around your j10-12 depending on its length."

How do I tell the -ve end from the +ve end?  Is it by using the arrow on the body that is pointing toward one end?  I don't see +/- signs anywhere on the component itself.

Can you please tell me what color the bands are on R3?  I can't make it out from the pic and there are a couple in my batch that look similar. 

Thanks!
