ADD HINGES to existing removable DUST COVER

Hi Elliot. Don’t do it! It will hurt the sound by acting as an acoustic feedback generator feeding amplified noise back into the plinth.

You could add self-adhesive felt or something to the underside edges of the lid to prevent the scratching concerns.

Over the tube amp in my living room I use an antique silk scarf as a dust cover. The scarf has had more compliments than the amp.

I have to agree with noromance.  Continue to remove the dust cover when listening.   All the discussion about vibration control on many threads argues against it.  

Agree the dust cover is a sonic nightmare. Good luck on your search - how could three tonearm be wrong !!!!!!!

Hi Elliott, I know where your coming from. My place is dusty as well. My solution is going to be to drape something over it as someone stated.
I'm not concerned about acoustic feedback as my tt is behind a short stubwall separating the living room from the dining room.
The main problem your going to have is finding hinges that will give enough support. The covers are heavy and front to back they are deep giving more leverage to make the lid want to close. It may take 4,5 or even 6 hinges to give you the support you need. Instead I would use two good hinges and build a nice prop rod like you would find on the original Pioneer PL-41 tt.
I assume you have been to Yahoo Japan, that will be the most likely place to find a 3 arm plinth but shipping is going to be expensive.

Dust cover when turntable is not in use, fine.Dust cover during LP play, no.Hinges for dust cover, no, no.  When it's off the turntable during its use, you want it OFF the turntable.
My opinion borne of experience, only.

Never play a turntable with dust cover on as its a static magnet.You don't really need hinges but this of course is up to you.Good luck.

I've never had a problem playing with the dustcover on unless I'm blasting the music. At normal levels it adds nothing.

Yeah, bad idea, I didn't think it thru. I don't ever play with cover in place, never did.

I used to leave my smaller TT's dust cover up/open while playing, lift it fully off for real listening sessions. It was also about 7" lower than this one is.

This one, larger and starting higher would be HUGE looking when open, that's unacceptable.  

Which of Lily Tomlin's characters said 'Never Mind'?

That was Gilda Radner on Saturday Night Live

Good point Elliott. How about a system of pulleys so you can raise it straight up to the ceiling when your using the TT. Think the better half would approve? LOL

My current removable system works now as you know, but as I approach enfeeblement, a crash down upon my Blackbird would put me in the hospital with apoplexy whatever that is (doesn't sound good).

Yeah, Gilda, I often confuse her and Lily.

I should have been more clear, it was the character Emily Litella, an old woman with a hearing problem, played by Gilda Radner
