Members hangwire Posted December 2, 2012 Members Share Posted December 2, 2012 ??? title says it.i know resistors dont, but do the capacitors? or do they just all need to be the same direction with the printed values facing the same way?how about the transistors? on the PC board the outline makes it look like the side that has the middle leg out in front a bit should face that waythanks Link to comment Share on other sites More sharing options...
Members tedmich Posted December 2, 2012 Members Share Posted December 2, 2012 yes, many caps are polarized, many aren'ttransistors are not only directional, they're chiral! Link to comment Share on other sites More sharing options...

Members echodeluxe Posted December 2, 2012 Members Share Posted December 2, 2012 Oh can tell if a cap is polarized by looking at it usually. There should be a stripe indicating the negative side.I'm on my phone otherwise I'd provide photo evidence. Link to comment Share on other sites More sharing options...
Members Reaganomics! Posted December 2, 2012 Members Share Posted December 2, 2012 you really need to just post a picture of what you have. I'd say most brown caps aren't polarized, but if they're tantalum or really old oddball paper caps they might be brown and polarized.Transistors have three legs and they all need to be in the exact right place in the circuit or they won't work. If you have metal can (silver) transistors that means you have Bipolar Junction Transistors so the three legs are the Emitter, Base and Collector.You really need to figure out what exact model/kind you have so you can figure out the pinout. They're mostly the same but you can never be totally sure until you've researched it. When beginners are building a circuit, having the transitstor oriented wrong is maybe the most common problem in a non-working build. Link to comment Share on other sites More sharing options...

Members hangwire Posted December 2, 2012 Author Members Share Posted December 2, 2012 also, a 0 ohm resistor that is just serving as a jumper... is it a resistor that is just 1 black line, or could it be a blue cyclinder with a black line ?

Members Faldoe Posted December 2, 2012 Members Share Posted December 2, 2012 whats the kit?Also, radioshack probably has IC sockets - not sure if they have transistor sockets. You could buy an IC one and cut it up to work with the trannie. Link to comment Share on other sites More sharing options...

As for the transistor, on the board D shape really more indicative of how to orient a black silicon transistor in a TO-92 case. Your transistor is in a different case and I don't know if it's PNP or NPN so the symbol on the board might not be helpful. In pretty much any transistor the middle leg, then one that sits "forward" is almost always in the middle pad on the board so the whole transistor could really face either way. It's the outside ones you have to be sure about. Who makes the fuzz kit? If I could find more info about their board layout or the schematic I could tell you for sure. If it's pretty close to the original mosrite fuzzrite circuit it's using an PNP germanium transistor with this layout . According to the circuit the emitter (e) goes to ground. If you can see the traces on the board and figure out which of the transistor pads connects to the ground then orient it that way. If we're trusting that the "D" shape follows the traditional silicon NPN layout then the forward leg of your transistor probably faces the curve of the D and the two 'back' legs face the flat part of the D.

Any 0 ohm resistor I've seen is probably a brown resistor with a black line in the middle of the cylinder. Link to comment Share on other sites More sharing options...

Members hangwire Posted December 3, 2012 Author Members Share Posted December 3, 2012 Q1 and Q2 they are 2n2369a that part under the transistors is that o ohm resistor? looks more like a diode from memory of what a diode looks like... Link to comment Share on other sites More sharing options...
Members echodeluxe Posted December 3, 2012 Members Share Posted December 3, 2012 A 0 ohm resistor would be a piece of wire The thing on the bottom of the picture is a diode. That absolutely must go in the correct direction. The caps in the picture, however, are not polarized. Link to comment Share on other sites More sharing options...
Members Reaganomics! Posted December 3, 2012 Members Share Posted December 3, 2012 OK so the 2n2369a is an NPN silicon transistor so that circuit is modified from the original fuzzrite. The metal tab that sticks out of the case indicates where the emitter leg. That still goes to ground. You can't see it but the ground is at the bottom of the board as pictured so make sure the transistor leg nearest to that tab is facing down; the 'forward leg' is going to be facing to the right.Edit: the blue cylinder thing is probably a diode, but GGG website doesn't indicate any diode in that kit so I don't know why it's there. If you want to be super sure, just save one of the resistor legs you snip off and put it in the jumper spot on the board. It's the same difference as EchoD said.

Members AluminumFalcon Posted December 3, 2012 Members Share Posted December 3, 2012 Originally Posted by Reaganomics! There's no diode in that kit so that's probably the jumper. If you want to be sure make sure the jumper is the last thing you put in, and that blue thing will likely be leftover.

It looks like on the PCB there's a spot for "D1" which should be where that diode goes. Match up the stripe on the diode with the stripe on the PCB. Easy peasy.

Easy peasy. its not in the bill of materials and not in the wiring diargam [the board is only half populated] Link to comment Share on other sites More sharing options...
Members cryptosonic Posted December 3, 2012 Members Share Posted December 3, 2012 It appears to be a polarity protection diode based on the wiring diagram showing the PCB traces. Go ahead and toss it in there. Link to comment Share on other sites More sharing options...

Go ahead and toss it in there. does it matter which direction since it is just jumpering? also, seems tab side should face down as the pic shows as emiter would be lower leg Link to comment Share on other sites More sharing options...
Members Reaganomics! Posted December 3, 2012 Members Share Posted December 3, 2012 That seems to be an "all purpose board" that GGG uses for several different circuits. The D1 is not anywhere in the kits bill of materials/layout. I mean, I guess it is a diode on second look but GGG doesn't seem to include it on the board so I'm not sure I'd put it at D1 Link to comment Share on other sites More sharing options...
Members cryptosonic Posted December 3, 2012 Members Share Posted December 3, 2012 It sure does. That isn't just a jumper it's a diode meant to protect your circuit should you hook it up to a PSU with incorrect polarity. The striped end matches up with the stripe on the PCB.
