    OCD OCI

    These engines don’t drain the filter until you remove the filter cover which pulls a plug from the center of the filter. Or bolt in my case (S52). New element comes with the cover o ring, copper washers for the bolt and drain plug and the o ring for the center bolt (or plug if you have a...

    OCD OCI

    You’re probably fine at two years if synthetic. Dino oil forms a lot of paraffin. If you had a turbo I’d say 3-5k max. Best thing to know is to have the oil tested.

    M300 Gauge Clone

    A good machinist is mindful of the order of operations… But jig plate is very flat and very stable. If thickness was right it could probably be used off the shelf and meet .002 across the corners of such a small piece. I think it is sold at .003/foot max deviation. Bronze is another option...

    M300 Gauge Clone

    I’m sure the main piece could be made from aluminum jig plate. And it could be Blanchard ground if needed. That small part would be flat within a few tenths easily.

    How do you clean your heads?

    IPA puts the contaminants into solution and then it evaporates, so they get re dispersed. We ran into this at a former employer who had the habit of ultrasonic cleaning grit blasted samples in IPA to remove the grit before coating, but when they did they would apply a micro film of oil over...

    M300 Gauge Clone

    Flatness is usually total, not +/-. Like TIR. Some shell dimensions are not critical but others are critical. They have different tolerancing on different areas of the same part.

    M300 Gauge Clone

    I don't see any tolerance on the first drawing... That's the problem with reverse-engineering: you don't know if what you are referencing (copying) is at mid-tolerance, or top/bottom of allowable tolerance.

    Any thoughts on S.E. to balanced signal conversion?

    Any thoughts on S.E. to balanced signal conversion?

    I discussed this topic at length with Wyn Palmer because a phono cartridge is intrinsically balanced. It also is a very low level signal that could benefit from all the noise rejection it can get due to the upcoming gain stage… But adding the SE to balanced conversion within the main board...
