now need make service to a motor, i have rumble

hi

my 5c sounds like a bad 78rpm record fro mthe 20's.... but i think its because I only have metal stylus'.

I plan on buying a proper sapphire stylus to test. the rest of the 5C was fully restored by Todd at deepgrooves.

There are some recordings on this forum made with 5C which sound really nice...

I also use his sapphires and emboss on polycarbonate. But I use lighter fluid instead of the Turtle Wax. (Ronson Fluid) Also, I run an ionizer in the room for a while before I start cutting and then let that cook in the background. I am getting some really good sounding cuts. However, I'm also cutting with a 1C head on both my K8 and 6N.

Maybe look to upgrade the head to a 1C/1D?

I'll post a file soon to show what I'm getting out of mine, would be really helpful to compare what you guys are getting if you wouldnt mind posting audio examples of your cuts?

I use a dropper bottle: (4oz is just an example)
https://www.amazon.com/Amber-Glass-Bottle-glass-Dropper/dp/B004TS3NOO?ref_=Oct_RAsinC_Ajax_318067011_5&pf_rd_r=E0138V7VZP35TVJV1ANN&pf_rd_p=dc09bd76-2291-5906-83a9-1291fe8d0ed6&pf_rd_s=merchandised-search-6&pf_rd_t=101&pf_rd_i=318067011&pf_rd_m=ATVPDKIKX0DER&th=1

Typically I wipe it off with some kind of rag. Could be an old t-shirt or whatever.

I still need to hook up my rig to record my cut playback into digital form but I'd be game because I've been slacking on putting any effort into that piece. I've been doing it by ear and while I've gotten way better I do burn a lot of plastic. But I like messing with knobs and whatnot by hand.

About 80% of the “farm fresh” 5cs (and RCA Tombstone) heads I’ve ever found have had volume and distortion problems, similar to Maximos. The rubber armature damper has disintegrated over the years and either gotten sticky and welded the armature in place, or is allowing metal on metal contact of the pivot.

You can fix it if you are careful. You can pull the armature out, (being very conscientious of the coil (most of the heads I’ve gotten had working coils and just needed cleaning), scrape as much gunk off the armature and the mating plate, throw the armature in a $30 ultrasonic jewelry cleaner, and put it back together.

I repaired 3 of them yesterday and have one more to go today. I will post photos later today.
