I'm back with a new Instructable! Wheeyy!
In this 'able, I'll show you how to make a Low-Voltage (Around 60 Volts) Tube Pre Amplifier for your Guitar!
Youll need, lets say Basic Electronics Knowledge for this.
Ive uploaded some examples with different Pickups and Gain settings.
Youll' need a mediaplayer that is able to encode AAC Music Files. Apple Quick Time Player should do the Job.
Step 1: Parts Youll need
I've listed all parts youll need here.
One thing I have to say before I write further.
I cant' tell you the exact sizes of the holes etc you need to drill because it depends on which parts you use and what kind of housing you choose.
So, Youll need :
1 12AX7 or ECC83 Tube
1 9 Pin Tube Socket + Screws
1 200V 470uF Electrolytic Capacitor
1 1M Ohm Logaritmic Pot
1 100k Ohm Logaritmic Pot
2 Switches, 1 DPDT and 1 SPDT
2 35 V 2.2uF Electrolytic Capacitors
2 6.3mm Jacks
1 400V 0.68uF Polyester Capacitor
1 100V 1uF Poly Capacitor
Lots of wire.
2 4.7k Ohm 1/4 Watt or Higher
1 68k Ohm 1/8 Watt or Higher
2 100k Ohm 1/2 Watt or Higher
3 10k Ohm 1/4 Watt or Higher
1 1.5k Ohm 1/4 Watt or Higher
1 100k Ohm 1/4 Watt or Higher
Wirecutters + Strippers
Needle Nose Pliers could be helpfull
Drill to drill holes in your Case
