I have a Wurlitzer 1015 with the SuperSound preamp and cartridge installed. I am also using a set of the Rhino 78 RPM reproduction "micro-groove" records. My question is which replacement needle is recommended for these micro-groove 78 RPM records (78 or45)?

It depends on the stylus that was used to cut the masters. Since I believe that these records were primarily produced for jukeboxes, you would "think" that a 78rpm stylus would have been used! Also if the grooves cover most of the surface area of the records (like a typical 78rpm record), that would point to a 78rpm stylus. Are you using a 78rpm stylus at present, is it a Stanton cartridge you're using?

Thank you for responding. It appears to be a modified (A dab of silicone between the needle and plastic housing)Stanton needle. It also has a blue rectangle marking on the front.

I would GUESS, that if the Rhino records are marked "Microgroove" but no "stereo" markings on them, a 1 mill needle should be used ? FYI-- &78's were made with 3,2,1, and .07 grooves, as far as I know. Ron Rich

Hi all,
From what we know the repro-78 rpm records get played with a 2 mil needle.
If I remember right we did sent a 1 mil and a 2 mil needle (for Aststic 51-2 cartridge) to a customer a few years ago. I mentioned that the 2 mil should be the right one to use but wasn't sure. So I suggested him to send both and give me a feedback.
Luckily he did so and confirmed that the 2 mil sounded better on his repro 78s (vinyl).
Victory Glass lists the 2 mil needles also for repro 78s.

I appreciate all the responses. I opened up a brand new SuperSound kit that I have been saving (for 30 years!) for my next project. The paperwork doesn't mention anything regarding needle specs. Having purchased the kit and records from Victory Glass, I contacted them and Steve assured me that the SuperSound needle, part #10-2275 for 78’s, was indeed the proper one for the Rhino 78's and it was 2.3 mil. So I ordered it. The needle sent was manufactured by Pfanstiehl as a direct replacement for the Stanton D5127. Victory Glass modifies them(A dab of silicone between the needle and plastic housing) to match the needle shipped with the SuperSound Kit. The label on the needle package states the tip radius as 3 mil. The needle itself has a green rectangle on it. Both my original Stanton 500 needles have a blue rectangle. Don't know if the color codes mean anything? Sounds like between a 2-3 mil needle is acceptable? Last thing I want to do is ruin one of these records.... Thanks again for all the help.

I have played these records in all my boxes (500, 800, 750, 1015, 1100). Most have Astatic cartridges with either original needles or the Pfannstiel replacements. In some of the boxes I have a mix of shellack and Vinyl reproduction, using 2 mil. More important even than 2 mil. maybe 1 mil. when playing the vinyl discs, is to reduce the weight of the tonearm. As they used to be calibrated to play shellack, which takes more weight than vinyl, you should reduce that. On the 1015 this isn’t much of a hassle.
