Appex, thanks for your great circuits! I am going to build this ML3 preamp with ur QUASI amp for my Bass Guitar. In our country buying Hertke,Roland,Fender.... r really expensive as they include 70% govt. tax 🙁 So its a real help for me.
tell me is that volume control with ML3 enough for my setup or I hv to add one log pot to the input of my amp? The 15V power supply needs how much Ampere?

In post #35 you have bass guitar amp, ML3 is universal preamp, volume control is enough. Use PSU +/-15V 500mA.

Is there any problem if I use QAUSI amp? I was planning to make it by two 2N3055 at +/- 30V DC as the circuit seems simple to me.
Thanx.
Thanx.
Quasi amp is clone of some old DYNACORD powered mixer, and no problem at all to use it for instrumental amplifier.

hello apex
can you give me preamplifier schematic that its output should have at least 300mV with mic in and aux inputs

is this pre amp suits for 600ohms dynamic microphone does it produce any noise
how can i add one more mic and aux?
what will be the output voltage
can i use LM741 instead of TL072
sorry for too many questions

No noise with 600ohms dynamic microfone
For more channels uso more ML3 preamps and mix outputs
Output voltage is 1,5V rms
No LM741 is single OP, TL072 is dual.
Apex,
Many thanks for sharing your project with us.
I'm wondering do you have any plan to make electronic x over with phase control and parametric eq in one board?

APEX do you have a 2 band tone control made with transistors instead of opamps?
you posted a tone control circuit a long time ago with a tl074 quad operational amplifier).its working good.i attach a photo of it. do you have the same circuit with pcb but with 2 opamps? i have 2 opa2134 (dual operational amplifiers) and i want to use them.

I have several active x-overs for active speakers and subwoofers, and I will share diy versions.
