I said I would never buy another Turntable...Argh !!!

[Lagonda]

I remember the car well when it first came out we were living in UK and my friend got one of the first 10 off the production, it was difficult to service it back then how do you do it now?

david

Used to have it serviced in Palm Beach, until they told me the guy that could fix it was retiring ! A couple of times they had to call England and check with the
people that had hand built it, the engine has a brass plaque with the builders
name engraved, and he would know where he put the relays and such.
These days most of the stuff that breaks has been fixed before, and i know
where everything is now. Keeping the relays and connectors rust free saves
you a lot of headaches. Most parts are shared with other cars, brake part, and rear axel part are Jaguar, transmission parts are Mopar, aircon is GM.
Sometimes you run into a part that is out of production, and there is actually
a club that share information on repair and parts, and meet once a year
for Lagonda Fest, this year in Holland ! Driving dining and comparing cars !

Christian, where is the TT located in relation to the beam? I have a thought about what might be happening, and an approach of direct correction is better than just throwing reinforcements at it, unsure.

The TT is between the new beam and the wall. Only about 2' inside of the new beam. We shall see what my General Conractor has to say.

 

[rockitman]

The issue...there is 32' of floor (running from speakers to the other side of room/house that has no beam support under it...only the stiffness of the floor joists which are flexing. Removing the floor bounce will go a long way to solve the problem with the AF1. The AS 2000 stand will be sitting on 3/8" steel plate 36"x24". Some have mentioned shelves on the walls....not really feasible for me(setup logistics)...nor the heavy AF1.

 

[rockitman]

I know it will deal with the floor while tt is playing and the resonance from the bass won't affect it either but we have see how it deals with Chris stomping around.

david

This is where RTR tape really shines....foot fall all you want !

 

[microstrip]

Well I learned something new today....Wood joisted floors are springy...so much so that heavy walking makes the AF1 stylus skip. Looks like I will be adding 32’ of support beam to stop/reduce the spring in the fooor. Since going Vinyl again in 2010, I was on concrete basement flooring and clearly never experienced this problem.

David will probably veto it, but are the ideal candidate for an active suspension system!
Footfall on old labs having bouncy floors is their specialty!

 

[Kingsrule]

This floor deal will be interesting..I've had several go arounds with suspended floors. The flex never goes away.

Your GC should have addressed that 32' while building the house. Don't pay him anything to fix it. I hate GC's and their afterwords up charges for their mistakes. Or point to architect ....

My GC didn't build the house....not his fault. Prior homeowner.

Have my tt w highly sensitive linear tracking arm on a Stacore Adv platform on a non specialist springy 35x30 floor, floating new floor on existing 1861 floor joists.

In my old apartment, in a converted industrial lofts building, the floor was wood on existing reinforced concrete, zero flex, my tt was on my Symposium rack, yet I could never quite isolate the tt fully, esp re freedom of linear tracking arm action.

Here, with the floor more an issue structurally, and the tt/Stacore unit directly floor mounted less than 3' from my floor firing subs, my analog has never sounded better, arm skipping a thing of the past.

I cannot extol the virtues of Stacore enough, esp re comprehensive tt isolation duties.

Hey C,

Lovely new home and what a wonderful listening room!

As you know, you have gone all-out and there is a lot of weight hanging out there .

Since you do not know how the original floor loads were calculated and designed, along with the as possible above-mentioned builder directed variances, it might be prudent to bring in a licensed mechanical engineer to evaluate, calculate, design, and directly supervise any corrective requirements that might be necessary.

...otherwise, you might be unexpectedly back to listening in the basement....

Happy Listening,

That was my point as well a few days ago. It was very inexpensive and I too had the worry that may floor wouldn't support the load.As stated as a result my sub floor was built for a tolerance of 1500 lb/sq ft which is way in excess of the residential and industrial norm

I have wood floors on Kinetics Noise Control blocks sitting on a slab. This did not work for my turntable. That's why my turntable and other sensitive equipment is in another, completely decoupled, room!

And where are you in relation to the beam when you can make the needle skip?

I thought they only made barrier walls. Isolated floors are a whole level of bounciness by design thankfully we're not dealing with that.

So I think definitely there is a way for horns to do psychedelic .
Tang

I think you meant "you definitely need to do psychedelics to listen to horns".
Been there. Done that. in my freshman year a guy down the hall had Klipshorns in an 8 x 12 cinder block dorm room driven by Marantz 9's. Listened to everything on psychedelics including "the sound of one hand clapping". Imaging? From a galaxy far, far away. Nobody cared.

 

[rockitman]

Contractor on it...the floor wasn't done right support wise...situation will be rectified.

Great news, Christian. I would love to hear specifics if you can describe them as the project continues.

It would still be helpful for me to know, for my own personal reference, where walking causes a problem in relation to the beam.

 

[rockitman]

It would still be helpful for me to know, for my own personal reference, where walking causes a problem in relation to the beam.

The newly supported floor section gets cantilevered (moves) when the rest of the not properly supported floor deflects. You could feel the vibration in the beam when walking briskly on the floor in the room above. Once more support trusses and blocking is added along with screwing floorboards from underneath, I will have a much stiffer support that should be reasonably foot fall resistant.

 

[Folsom]

That's what I thought was happening, but perspective and measuring from photos in my brain wasn't sufficient data. You basically created a teeter-totter. Can you ask about putting some rubber between the beam or rods and the floor joists? That'll help some even as you add more support to stop the effects you have now.
