Question about opamp, resistor and capacitor?
1.Im going to build a ROG Tonemender (http://www.runoffgroove.com/tonemender.html).What the 10M resistor do in this schematic ? and its ok if i use a smaller value like 2M or 4M7 ??
2.If a opamp rated output 10W with 4 Ohms speaker, how many W i can get if i connect it with a 8 Ohms speaker ?? can i have the formula for this please.
3.My amp have output power is 100W , can i connect a 8 Ohms 26W speaker to the amp ?
4.I want to find an opamp like LM386 but use lower supply voltage (5v) can you give me some suggest please.
5.What type of capacitor in the picture bellow ?
Thanks for advance.
sorry for my bad English!
