2n5306 Transistors pinout or DOD?

I'm building a scrambler clone from the kit on General Guitar Gadgets.
On the transistors I have a problem testing. After triple checking every
solder joint and resister and cap. The pedal does'nt work. I moved on to the transistors...
My multimeter(radio shack) does'nt read any ohm's on any on the
10ea. -2N5306 transistors I purchased. I tested them on the circuit and unsoldered.
I tested 2N2309 and some diodes (1N4148) with success but are the 2N5306 dead?
Can anyone help? The pinout on fuzzcentral for 2N5306 is:

1: Emitter
2: Collector
3: Base

But on the Guitar gadgets website the callout is:

1: Emitter
2: Base
3: Collector

I should be able to test these before soldering to the board.
But I get no readings! What Im I doing wrong?
Any help would be very appreciated greatly.

Looking at the flat side from left to right it is E,C,B.
Make sure the right legs go in the right places is all.

Good luck,

have you tried plugging in more than two tranistors and trying them?

Does your meter have a diode setting? if so go to this site and read"how to figure out your mystery transistors" and it will show you how to go about figuring out your trannies.

Best of luck~!!!

Hey man, I recently built a Scrambler and had quite a time figuring out what was wrong with the thing.  The sound always got grounded out at the transistors.  What I finally figured out was that I had put the 2n5306's in wrong because I thought their pinout was E B C, but was actually E C B.  Apparently, putting them into the circuit like that and powering up killed them dead.  If you got the trannys from Small Bear, then they are definitely E C B.  So what I did was buy more transistors and triple check their orientation.  Now it works like doom.

I also put the 2N5306's in wrong on my Scrambler project and got no sound when the effect was switched on. I checked the pinout diagram at General Guitar Gadgets, bent the pins to get the right orientation, and when I fired up the effect, no fuzz, distortion or octave could be found, just a slightly weaker guitar signal. Does this mean that the transistors are probably fried?

When I found out my trans were in backwards, I switched them around and still got nothing at all.  I eventually found some other med-gain transistors at my house and stuck them to see what would happen, and then it worked.  It didn't sound as good as it does now, but you could tell it was Scramblerifying the sound so to speak.  Later I ordered the trans again and now it works perfectly.

This forum rocks...the help one can get is incredible...
I love this stuff!

Veeery old thread, but I just had the same problem:
There seem to be two different pinouts for the 2n5306, both from Fairchild:

Very strange!
