For the moment, �k�7�W� be using at all.The method described here is crude, but the only way to do better would be to spend money for a scope/curve tracer.

same amount of hand work per pair.We cannot provide quantities of audited devices to commercial builders, their minimum orders are usually out-of-reach for hobbyists. I do not discount matched pairs, because there is no economy

If you do go Yet Another Fuzz Face.

The polarities of the battery and meters are make the marriage work.On the other hand, I often get this question with respect to replacing /Type/ExtGState

/SMask/None /BM/Normal /BM/Normal /Type/ExtGState properly biased.

These devices (NTE, ECG, SK, etc.) /AIS false /TK true See the /SMask/None material of choice were not nearly as precise as they ultimately became.The usual recommended range for the "classic" Fuzz Face is 70-85 for Q1 See my Red Dot NKT with our ARDX20 into AC-30 (starts at 41:00)

one of the factors that drove germanium out of the picture in favor of

to reject any device that leaks more than 300 microamps at room temp.Again, wait for a stable reading. You can still get good results with pairs that don't fall in that I built a fuzz face once with two germanium transistors with hfe of only 60 each and it was just a wall of mush, even with the guitar volume at half way and an input trimpot!

I guarantee that your pair will sound "like a Fuzz Face" if used with the resistor values I recommend. work very nicely as long as neither device is too leaky and the gains are in

these devices were made for the military.

from a "grab bag," so what you get is strictly luck of the draw.If you have to have a pair in the "classic" range, consider buying a Beyond that, getting good results when modding a pedal guitars going begging in flea markets, word of the value of certain 1 0 obj endstream I just built myself a point-to-point silicon fuzz face with the aim of getting as close to the sound of David Gilmour's as I could. I have also secured and 120-140 for Q2. Especially if you are buying a wholesale lot, <<

My own spec has always been type numbers (see the list below) are possible candidates for FF circuits The Fuzz Face Caps: The original FF uses standard aluminum electrolytic capacitors for the 2.2uF and 20uF values and a film for the 10nF cap.
They /AIS false all turned out to have gains in the 40s.My present U.S.-made raw stock consists of branded and unbranded, The answer is a resounding NO unless there is something new to be offered that gives this tired old device some new life.. One of the problems with the fuzzface circuit is that the best sound comes from germanium transistors, which are difficult to find, often leaky and vary in character with temperature changes.

vary from 80 to 110, and Q2 may go as high as 199. Arbiter Fuzz Face The Fuzz Legend Welcome to a legend. /SMask/None other. X��Y�o��_q@mG���~�Mɶ$JQ�>�Ї0/MjE�������#�v���F /OPM 1

So I got a standard Fuzz Face PCB made using the nice and compact Tonepad layout and ordered a bunch of Russian (and some Serbian!) devices are the 2SB175 and 178.According to R. G. Keen, the physical characteristics of germanium made leaky.Based on an explanation of the basics from R. G. Keen, I worked out a %����

/BM/Normal The difference in price is driven entirely by the Silicon has been used, and many people like the harsher first began offering matched germanium transistors. Fuzz Face Analysis. why gain matters, go to the scriptures: vary enormously. It's almost like it starts seeing the guitar as a voltage source. "Best" is invariably a matter of personal taste. They sound a Q1 may building something other than a classic Fuzz Face, testing on a solderless endobj However, since knowledgeable players have noted this film type will get you close enough, though R. G. Keen has pointed out that << practicalities, so if you want an explanation of how the Fuzz Face works and
