Although, I'll have to ask a few more questions because my skill's in electronics are limited.
I can use a multimeter, make basic measurments and tests, I can de/solder through holes but that's it.
The M5213L is a 7pin IC and your suggestions are 8pin IC's. What should I look for in their datasheets in order to make it work? It's for a preamp's tone control section.
Should I make any other mods in my amp or it's ready to go?
Pin 8 on the DIL chip is not used so match pins 1 for 1, 2 for 2 etc. Pin1 is out a, 2 inverting input a, 3 non inverting input a, pin 4 -ve supply or ground if single rail supply. 5 non inverting input b, 6 inverting input b, 6 output b.
Hope that helps.
Just to be clear, I can substitute the M5213l with a TL071, right? No other mods needed?
Because I can easily find the TL071 locally (and super cheap! less than 1euro each). Finding the M5213l is impossible.
If you look at the circuit diagramme of your unit with the faulty M5213, you can confirm this. Otherwise it is basically from memory as there is no information on the M5213 to confirm it the other way.
What is the make and model of the faulty machine?
Hello there ! Have u replace the M5213L with TL071 with success? Have you made any adjustments? I have an AKAI AM-U55 with M5213L on preamplifier board and it makes very nasty noise on pause. And i want to replace that chip with a TL071.
