Hi everyone,
I have just acquired a really nice vintage Teac CD-Z500 cd player that uses two TDA1541A DACs, it sounds really nice in stock form but I would like to do some simple mods to get a bit more out of it like change the op-amps and install new capacitors.
It uses 2x Mitsubishi M5238L op-amps in the first stage and also 2x Mistsubishi M5238L in the second stage nearer the output rca's, would there be a drop in replacement that would sound better than these ancient op-amps? I would need to buy an adapter though and solder the op-amps onto them.
Also surrounding the 2x TDA1541A are many resistors which I find strange as there are usually capacitors surrounding them.
If anybody has any idea's I would be very grateful thanks.
I have uploaded a few pics of the dac board here:

Many thanks everyone
