Tim's Livingroom/Theater

Well since we have gotten a little off topic & are talking a bit about analog audio & idler drive turntables, i thought id show a few updated photos of my Lenco L75.

A lot of Lenco owners will purchase a second platter to stack on top of the original, therefore doubling the rotating mass to increase inertia & reduce transfer of vibrations. Well unfortunately i was unable to locate a second platter...so i designed & had something similar machined out of solid aluminum. It is 1" thick & is approx 11.75" in diameter. In order for the "platter extension" to line up with the original platter I had a brass spindle extension made as well. The brass is press fit into the aluminum platter & has been turned together for a seemless blend. The new platter fits like a glove over the original spindle.





Once the new platter was finished & installed i then had to raise the tonearm...no problem, raise the cradle...no worries...raise the arm lift...big problem! The original arm lift will not reach the tonearm once it has been raised 1". So i had to order some parts from McMaster Carr (large hardware company) I got a 3M coupling nut, 3M threaded rod & 3M smooth rod. These were perfect in getting the arm lift to the proper height so that it could reach the new tonearm level.

So after all that designing...machining...polishing...etc. I finally have a complete Lenco L75 rebuild that sounds great & is being used on a daily basis!! This has been one of the most fun projects that i have undertaken & the results have been nothing but pleasing. Here are a couple pictures of the final product. The aluminum record clamp was also made to spec at the machine shop that i use.









There are more photos of the turntable project in my photobucket acct that is linked in my signature if interested. I hope you enjoy the photos!!

Beautiful! How does she sound?

That looks amazing , but yields a negative reaction from me. I work at a machine shop in Ventura, when work and hobby combine......I get slightly annoyed.

On a sidenote you mind sharing what machine shop you use? I don't think my shop takes any public orders [we're oil manufacturing] and I doubt they'd even make something for me .

Afterlife: she sounds fantastic to me!! I don't have a lot of experience with TTs but as I made progress I could definately hear a very nice improvement. The biggest improvements coming from the new cartidge, trying different tubes in the phono stage & adding the platter & weight. It has really changed the way I enjoy music now!!! 👌

Grador: Well good thing I don't work at a machine shop because I enjoyed custom designing some of my table & seeing it all come together. The shop I used is a very small, owner/operator shop named VDJ Machining in Cerritos CA. The office I dispatch from is in the same bussiness complex so Ive known the guy for a while. He does all my machining. Sometimes he hooks little stuff up free & I'll get him gift card or something. Hes a good guy!!

Im hoping TLS Guy checks these pics out...I know he loves this side of audio equipment!!

I kid, I kid (mostly). I really like the look of the press fit brass spindle insert, and think the overall design is very attractive, hats off to you.

Grador:
Haha no worries!! Thank you for the compliment!! I know what you mean though...& I hope my response didn't come across sarcastic!!

DAMN YOU, you're costing me money. So your talk of bass transducers finally got to me, got a pair of aura pro bass shakers in my loveseat and am really enjoying them so far.

[timoteo]

Haha that's funny!! Yeah hang around these parts & talk with us & your bound to spend more money than you expected!! Well actually that's not true because a lot of times we save others money with good suggestions...it goes both ways I guess!!!

Shakers are fun actually & as long as they aren't turned up as to be distracting they can add a good effect to movies!!! Glad your enjoying them!! Make sure the phase is adjusted correctly so they are complimenting the sub & not fighting the tactile effect that the sub is producing!!!
