With this Expanded Range MN6042 Upgrade, holding down the reset button for ~2 seconds will cause the pitch display to start flashing, indicating you are in ER mode.  While in ER mode pitch changes are x10, e.g. 1.1% is 11%.  The available pitch range is -40/+20%.  To exist ER mode simply hold down reset for ~2 seconds and the display will stop flashing, indicating you are now in normal mode. 

This functionality is desirable for archiving LP's as slowing down replay will increase traceability and decrease distortion.  Pspatial Audio is adding wind-up from -25% for 33.3RPM records feature to their Stereo Lab software to facilitate this, as 25% slow is the sweet spot for the SP-10. 

Being early MOS technology, the Technics MN6042 Pitch Synthesizer IC is by far the most failure prone IC in the turntables that use it.  Further, at their current age, even working MN6042 ICs typically are not working well due to gate damage sustained over their lifetime.

In our testing of three different Technics ICs, we found all three exhibited an average frequency variation of 8Hz, which directly affects the Quartz Lock frequency of the turntable, leading to increased flutter.  With today's technology, we can do far better.

The Fidelis Analog FA6042 Pitch Synthesizer is a drop-in replacement for the original Technics part, designed for absolute reliability and vastly improved performance.  Our Pitch Synthesizer is stable to +0.1/-0.2Hz, making the Quartz Lock reference stable to +/-0.00003Hz as measured in our SP-10 MK3.

INSTALLATION NOTES: For an SP-15, replace R214 with the included resistor.  For an SP-10MK3, jumper R301 and lift R212.  The white dot on the board denotes pin 1.

Great Replacement
The good. A perfect fit for my left turn signal lamp. 2003 BMW 330XI. Works and looks good. Has weather seal. We will see how it stands up to the Florida rain and car washes. The bad: As you can see in the picture the right lens retainer clip came in broken, Probably damaged in shipping. No big deal I just needed the left, I'll probably just super glue it and store it as a spare. Overall I got my moneys worth and I'm happy. Product was as described and arrived on time. I will buy from this seller again.

Cheap enough to not really worry about
They fade to yellow pretty quickly, and get moisture in them. But they look good at the beginning!

Fit isn’t 100% but they do work and look pretty good.
The fit isn’t 100% it about a 90%. The light bulb doesn’t click and lock into place but not so loose that the bulb comes out, I’ve driven just a little serious with these on and they have held up. Moral of the story. Its definitely aftermarket and you get what you paid for but for what it is im pretty dang happy with them and maybe you will too. It does the job pretty well.
