Re: Is This Diode Germanium or Silicon?

1N914s are absolutely silicon. For all intents and purposes, the 1N914 is identical to the 1N4148, which is pretty much the most common small signal diode on the market today. There is also a pretty big difference between germanium and silicon diodes, as germanium diodes have a lower forward voltag...

Is This Diode Germanium or Silicon?

I'm onto my 2nd and 3rd DIY projects after completing my PNP Germanium Fuzz Face - an NPN Silicon FF and an MXR Distortion +. I've already bought most of the parts for the D+ from this Tonepad schematic ( http://tonepad.com/getFile.asp?id=6 ). I am having a hard time finding out whether the 1N914 Di...

Re: Ground and Metal Enclosures?

Okay, thank you. I had a ground wire giving me grief, and wanted to make sure the issue wasn't ground related.

Ground and Metal Enclosures?

I'm finishing up my Fuzz Face project, and want to make sure I've got the ground working correctly. If I test for continuity from the sleeve of one of the jacks and the inside of the metal enclosure I get a beep. Is this normal? Am I understanding correctly that a metal enclosure by nature will be c...

Re: Transistor Pinout?

Thank you for the help! I didn't update but actually found it online. The specs were in Russian, but someone suggested using Google Translate to figure out which was which. Finally got it, although unfortunately I fried them both :( . I picked up some cheap PNP Silicon transistors at Radio Shack and...

Re: First Time Build - No Sound

[smilie=dancing_cow.gif] [smilie=muffin.gif] It works!!!!! [smilie=muffin.gif] [smilie=dancing_cow.gif] Tonight I checked everything over once again, and got a magnifying glass out to look at the soldering work. I noticed the wire on the tip of the input jack looked precarious, and also last night w...

Re: First Time Build - No Sound

Update: I haven't ordered any new germanium transistors, but I was at the local Radio Shack tonight and bought a bag of 15 PNP silicon transistors for $3. I knew they probably wouldn't be great FF transistors, but I was hoping it would tell me whether my germaniums were bad. And my board has a 330k ...

Re: First Time Build - No Sound

There's no rhyme or reason to the black wire, it's still positive ground :)

I keep holding off having to order new transistors, but I may just have to do that. Will try a fresh battery first.

Re: First Time Build - No Sound

Thanks so much for explaining continuity to me. Knowing that helps a lot :) Before I re-installed the transistors because I realized the pinout was wrong I tested them in the hfe sockets in my multimeter and got a good reading from both. Does that mean they are both good? Or could I still get an hfe...

Re: First Time Build - No Sound

I hope I didn't breach some forum etiquette by going somewhere else. I certainly appreciate all of the help I've received here. I wouldn't have been able to get this far without you guys.

Re: First Time Build - No Sound

FYI, if you're looking at the picture of the underside of the board here's how I've wired it (holes on the right of picture, top to bottom):
1 - input
2/3 - ground to ring of input jack
4 - lug 2 fuzz
5 - 9v black in
6 - lug 3 fuzz
7 - lug 3 volume

Re: First Time Build - No Sound

Yesterday I got everything wired into the enclosure, realized the polarized capacitors were backwards, fixed that, plugged everything in and still nothing when the fuzz is engaged. I have a perfect bypass signal though. I tested the continuity into the board to the output and there's nothing. When t...

Can I slip some wire shielding over one of the legs or is there a better way?

Re: First Time Build - No Sound

Quick question: Can the transistor legs touch each other? The pinout is funky and I have to bend the base over the collector to make it fit, and they are touching.

Re: First Time Build - No Sound

Once you've got everything wired-up in the new enclosure, you should use your multimeter to check the voltages on the transistors, Q1 (the one with it's base connected to the 2u2 input capacitor) should have about -.5V on it's collector with respect to ground, Q2 ( the one with it's emitter connect...

Transistor Pinout?

I am building a DA Fuzz Face clone with 2 1t308b transistors (PNP Germanium). I'm having trouble finding accurate information about determining the collector and emitter. There is a red dot on the top, and I had read that that would be the collector, but then I read somewhere else that that is rever...

Re: First Time Build - No Sound

Ordered a larger enclosure , smaller switch (at least I thought it would be) and 5 feet of 4 different colors of wire from PedalPartsPlus and got it today. I love that place! I ordered the "Translucent Gold" color and it is just gorgeous! I drilled out the enclosure tonight and put in all the hardwa...

Re: First Time Build - No Sound

I'm not concerned with an LED or power. Just wanted my first to be as simple a build as possible. I just got some unexpected money today (Thank you God!) :applause: , so maybe I can get an enclosure and a switch. I'd like to keep the current enclosure and maybe try a treble booster or something for ...

Re: First Time Build - No Sound

Well, seeing as you need a bigger box (sometime when you can afford it), there's no harm in you driling extra holes in the existing box, right ? So, you could re-position the jacks away from the footswitch (or just move the footswitch away from the jacks), and then see if you can get a bypassed sig...

Re: First Time Build - No Sound

A good solder joint should be nice and shiny, with just enough solder to flow smoothly between the two parts being joined. Bad joints are usually dull looking, but you can also have a bad joint under a big blob of solder. You should be able to detect an open joint with your meter, but if it's an in...
