Default OPAmp replacement

Hi im new to all this but have really got the bug. Ive already upgraded the caps and opamps in my quad 405. I am now trying to upgrade the parts in my mitsubishi pre amp. If someone could spend a little time helping me i would be most grateful. The opamp in the pre is a m5214L is this chip any good or should i replace ?? if so what with. Can you still get this type of chip or would i need an adapter? and lastly would i just be able to swap them over without any mod to power supply??

Cheers, JP

According to the datasheet the m5214L looks like an amplifier in a SIP package. Not many modern opamps are available that way. You could either find something in a TO-39 package or wire up a small adapter board with a DIP/SOIC chip.

Hi,
the minimum you need is a schematic for the amplifier and the datasheet for the chip.
Then you can see what the manufuacturer recommends and what the assembler did with it.

Without that you are groping in the dark.
