So, I looked into building the LPB1, which is meant to be a beginners build. Schem looks simple enough... It's the parts list that has me lost!

I've tried locating the partss online, but I as I delve into the components section of the websites listed in the pedal building thread, it all gets confusing.

Parts list:

Resistors

1 - 830kohms
1 - 10Kohms
1 - 100Kohms
1 - 360 ohms

So I look up resistors... and I get sub-categories like "Carbon film" and "Metal film". Niether is dictated in the parts list, or the schem. So which do I need!?

Capacitors

2 - o.15 uF (electrolytic or similar)

Again, same problem. I look up electrolytic, and I get many a sub category. And I can't for the life of me locate a 0.15 uF capacitor.

Transistor

1 - 2n5088 (commonly found)

Okay, I've had very little trouble in this department. 'Commonly found' probably was a true statement.

Potentiometer(s)

1 - 100kohm log

No problem with pots, either.

Other

1 - Hammond 1590BB Alluminium Enclosure - found an enclosure.
1 - Switchcraft Mono 1/4" Jack - Jacks are easy to locate.
1 - Switchcraft Stereo 1/4" Jack
1 - DPDT Heavy duty Stomp switch - Found
1 - 9v Battery snap - I want to run it through the mains. Where can I find a DC jack?
1 - Perfboard
1 - Knob
? - Wire. 22AWG, solid core makes for easier soldering, buy colors! '22AWG' means nothing to me. Can anyone enlighten me?


I'd really appreciate it if someone could look through the list, and point me in the correct direction! I'm wanting to purchase it all from one site, but that's not looking likely. If you could locate them on www.maplin.co.uk or http://www.rshelectronics.co.uk/, that'd be bloody awesome.

I don't know if you guys have the British equivalent to Radioshack over there in England, but in the U.S.A. I would just take the list to a Radioshack and have them find everything for me.

I guess this is somewhat of a useless post . . .

Haha I'm having the same kinda problems, I'm planning on making the Little Gem amp, I Got my soldering iron, solder, wire, multimeter, perf board etc today from Maplins but they couldn't help with the components that I wanted.The guy who helped me said to either find them online or through the Maplins catalogue :/
I've already looked online and couldnt really find much

Heres the parts that I need:
Resistors:
10 Ohm Brown/Black/Black
Potentiometers:
5k Linear Taper Pot
25 Ohm Rhetostat
Capacitors:
0.01uF (Film)
0.047uF (Film)
100uF (Aluminium Elecrolytic)
220uF (Aluminium Elecrolytic)

Looks like we'll both have to get a Maplins catalogue :P
Good luck with your build

this place should have pretty much everything you need for you build. for resistors carbon or metal film will work carbon film resistors are usually cheaper, but it's up to you they both work. For the capacitors if you need electrolytic there would be a + on the schematic on one end of the capacitor in question otherwise a mylar/film cap will do the trick. All the other stuff should be on that site you just need to search for it.

metal film resistors usually have 1% tolerance, and are smaller and quieter than carbon comp/film. (if u want to be more vintage-correct, get carbon comp, but u probably won't notice any difference..).

for caps - try to avoid ceramic caps in audio.. so unless u can ONLY find a certain cap value under 'ceramic disk caps', get another one.
i use mostly polly-film caps.
electrolytic caps are mostly polarized - they have a + and a - lug, which means it matters how u put them in the circuit board..

uF means micro-farad. some sites use 'mF' - it's the same.
0.01 uF/mF = nF (nano farad), so u might bumb into 'nF' sometimes..
as a general rule, you can easily get a polly film cap for values up to 1uF.. so i'd avoid electrolytics for values under 1uF.

have fun

Yeah, I thought the futurelec site was awesome, till I realised it was american and im in the UK

I'm in UK too, they ship worldwide.
There's a United Kingdom option in the order form:

I don't see why those wouldn't work if that's what it calls for. I personally like these kind of caps better http://www.futurlec.com/Capacitors/C01UM.shtml but the ones you listed will work.

Either will work, but metal film ones are less susceptible to noise and closer to their written value.

Between Axial, and radial, right? You'll probably want axial, as the leads are on the ends of this cap.
Some sites refer to uF as mF. It's essentially the same value in this instance.

Any kind of wire works. 22AWG is the gauge, and it just means fairly thing, as thinner wire is more pliable and easier to solder.
