I am using a different 12" arm, but it has identical pivot to spindle specification. Why do you think its too long?

I am not familiar with the ceramic coating process, but I do have several corroded Japanese DD turntables. Is the coating difficult to apply? What it the process?
Post a picture. I'd like to see a 12" arm on the DK-300.

Thanks. Does the dustcover still operate correctly (don't see the hinges, etc.)?
Well............... when I think about a tonearm fitting on a plinth I'm thinking it fits with the stock dustcover. But, perhaps that's just me.

Hi Legrace, as I am sticking to the accompanying dk300 bought to avoid more $ spent, my understanding is that unlike 12" DA-308 that is actually 11.1", sme and some are true 12" and the dustcover will not closed up.
Will be most glad if advised otherwise.
Cheers.

Hi Belyin, after polishing off the oxidisation and wipe down with disinfectant wipe or any iso alcohol, it is just a light wipe down of the accompanying specially designed applicator (sponge top layer and hard foam bottom) and wait for 48hrs to be cured .. full curing may that a few weeks but fine to touch.
When wiping down the ceramic coating, it will be smooth and even but if there are any area missed or uneven (check at angle with some light or in daylight) since transparent and a quick touchup will make it perfect .. use enough of the coating and hard to go wrong.
Cheers.

Bought the DA-50 tonearm and looking at good condition UA-5045 at usd100 but aware of bad rubber damping material which I may not be able to repair... still not sure why the other available sme IV tonearm is hardly used with dp80 and without users' shared experiences in all forums

In my case, physically the cover clears the arm. I could introduce a small clearance hole into the armboard to allow the cables to pass through the plinth, versus draped over the back. But I'm with the crowd who prefer a coverless asthetic, so it's perfectly fine as is. The Dual you will note is also sans cover. I cannot vouch that every 12" arm will fit, but I suspect many should.

Bought the excellent looking UA-5045 TA with cable san headshell ... <usd100 hard to pass and having 4 accompanying armboards with the received dp-80/dk-300 has its temptations.Bought the DA-50 tonearm and looking at good condition UA-5045 at usd100 but aware of bad rubber damping material which I may not be able to repair... still not sure why the other available sme IV tonearm is hardly used with dp80 and without users' shared experiences in all forums
Hope the NOS unused AV-101S bought decade ago will work or the PLC-3 and PCL-7 that came with the DA-50 do so.
Cheers
Thanks so much for the info. I have a Victor TT-101 that could really use this treatment. Now to see if I can rub out the corrosion . . .

Most welcome ! Do take care to try polishing at less conspicious place when even using fine grit 3M maroon scotchbrite .. just in case it is anodised else the finishing will be damaged and wun look any better.
The platter edge of dp-80 is not anodised and already brushed finished for the similar fine grit 3M maroon scotchbrite and hence looks new after polishing.
Cheers.

Usd20 excluding shipping .. no hassle to hunt for individual ones and probably higher cost due to multiple shipments

Bad news
Installed the platter and found that motor is running at high speed i.e. not locked and electronic brake is not working when stop button is pressed. Checked the platter on its inner brown magnetic strip to be in perfect condition and adjusted magnetic head gap with both biz card and A4 paper as googled on such issue but to no avail.
While Japan seller reportedly was using it without problem after being serviced prior year, I had stupidly not checked with platter mounted when received and only noted the spindle was moving.
Will disassemble tmrw to check on any wrongly soldered capacitor, poor soldering etc. Any idea on fix(es) to try out as this is certainly being me without knowledge nor equipment to diagnose ?
Any contact for repair at worst case as I do not believe there is anyone in Singapore who can do so ? TIA.

Hi Mark, Did you encounter motor running in crazily high speed and pressing stop button seems to have electronic braking not working like what I am experiencing now as shared above and adjusting VR1 and VR2 solves such issues ?
Kindly note that recap also already included changing out 6 transistors per kit from ebay seller.
Thanks and cheers.
