file has the parts list along with the circuit board layout. This is not a RatShack project so you will have to order online from Small Bear Electronics or another reputable electronic parts dealer such as Digikey
, or MCMinone
if you are not lucky enough to live in a city with a decent electronic parts store. I use metal film resistors instead of carbon film due to there tighter tolerance range (10% or 5% for carbon vs. 1% metal film margin of error) and if you buy an assortment online you can get them in bulk pretty cheap.
You can cross reference the IC's and transistors online at NTE
to find the "generic" NTE version, which are usually easier to find locally. Audiophile types frown upon using NTE parts for high-end projects such as amplifier rebuilds do to inconsistencies in part specs but for projects like this I haven't had any problems so far.
Not stated in the schematic but is assumed knowledge is: All resistors are 1/4 watt , all capacitors need to be rated for 12 volts or higher. (a 12V .01uF capacitor and a 50V .01uF are the same except the 50V can take more voltage and will be bigger in size in case you were curious.)
In addition to the parts listed in the PDF file, you will also need:
- Qty. 3 - 100K-A (Audio or Logarithmic (same thing) Potentiometers - 17mm diameter fit better
(careful not to get Linear taper Pots.... big difference!)
- 3PDT stomp switch (Small Bear Elec, or Ebay)
- 9V battery snap and battery Clip,
- LED and LED holder (if you want a status indicator)
-1/4" Stereo input jack
-1/4" Mono input jack
-22 Gauge stranded hookup wire (preferable 3 different colors)
- 9V "wall wort" power supply (center conductor is " - ")
(this can be a salvaged one rated around 500 milliamps or so)
- power supply connector (female, that matches the connector on the power supply)
-Suitable case (preferable metal for strength and shielding.) Check the web.. Hammond cases are the most popular. I found mine at my local electronics part dealer.
*edit* My last trip back to the store I found out the company and the part # of the case...
The company is: LMB Heeger (they have a website also) and the case is # MDC532
Other Supplies & Tools:
Soldering iron, Solder, Drill/Dremel, Drill Bits, Clothes Iron, Plastic Containers, Rubber Gloves, PCB etchant (Ferric Chloride), Multimeter (for testing/troubleshooting), and cold beer.
