Thorens TD150/160/166 plinth solid or hollow
I am going to either build or buy a new plinth for my Thorens TTs and wondered if a high mass one like the ones for Lencos would work,
i.e. plywood and veneer
This is in Cherry
This is in Rosewood Venner 17kg
Here is a hollow box plinth in Santos Rosewood
Here is a solid ply and Rosewood veneer
here's a solid one with a TD150
layers-of-beauty - gallery
or would it have to be the simple box frame?
Here is the traditional plinth in solid mahogany from the same guy
Can anyone explain what type would or wouldn't work and why?
I have no commercial interest or link with the above company apart from thinking about buying one of their plinths.
Any advice welcome
Suspended tables like the Thorens TD150/160 don't seem to get the "high mass" treatment like other "non suspended" tables like the TD124, SP10, GL75 etc. This is based on personal observation, not on actual experience building plinths. It could be that all turntables benefit from "high mass" plinths, just suspended tables less so.
I've seen some lovely lower mass plinths lately for the TD150, built from layers of Baltic Birch, and then painted with high gloss automotive lacquer. I do love the look of wood though, especially on an older "classic" table.
Take a look through the Thorens_Gallery
High mass plinths are not very common with suspended TTs. Not sure why, must be the Linn "philosophy" :). Still, years ago i built a slate plinth for a TD150 and it turned out great. The TD125 which in my eyes and ears is a better tt than the LP12 is high mass. And so are the Prestige and Reference.
I tried for years to try to tame turntables for dance music.
If you want to know what works try putting your turntable in front of a 6KW efficient PA!
For me high mass wins, but the most important thing is the support. It pains me to see someone spend all that time making a turntable, and then sticking it on a resonant cabinet.
The best support I have found is a braced wall mounted shelf. The wall should of course be solid. The referencing of the turntable to such an imovable object is what makes the difference.
I have experience of nightclubs, back in the Vinyl only days, where the simple addition of 2 brick piers, One under each turntable, referenced to solid foundations, totally transformed the fortunes of the club. All of a sudden the punters had tunes that they could dance to. Very soon the club was full every weekend;)
Here's the update,
I have emailed Russ for a quote on a cherry plinth, as that seems to be my favourite wood.
Meanwhile I have put together a solid 140mm African Walnut plinth as I wanted to give it a go anyway. I wished I had purchased American Walnut as its a lighter wood, but hey ho :oops: I am going to use it with a TD 160MKIIB that I will build with parts from ebay.
I a not a woodworker and have very limited tools and experience. The hardest thing is the mitred joints, I just can't get them as good as a factory or professional would. I did try using 'plastic wood' to fill in the gaps but its been a big mistake to be honest, I will never use it again.
Anyway comments appreciated, I have used Danish Oil to finish and am up to
3 coats now rubbing with 000 grade wire wool in between.
Any advice on finishing and the corners would be appreciated.
I have bought some rega planar 3 rubber feet of ebay as the majotiy opinion seemed to be rubber over spikes.
I have used an 18mm piece of MDF for the base.
Look forward to comments and advice :D
At least you are not camera-shy :rolleyes:
I found replacing the stock plinth on my TD-125 with a considerably heavier one made a huge difference for the better particularly in terms of the bass.. Overall noise floor seemed to drop slightly as well.
I am beginning to doubt that even a csd (constrained layer damping) plinth would be overkill for a good suspended table. The motor board is usually directly coupled to the plinth and the heavier plinth should act as a more effective sink for low frequency motor vibration IMHO..
Here is the plinth with my TD166MKII in African Walnut
I have just done a strait transplant without any mods for now, as I want to get it fully working, and modify it over time. I already have some parts ready to go such as metal inner platter to replace the composite one.
I fired up the TT and was immediately struck by the level of base in the music however the left channel is much quieter than the right one so that everything sounds as though its coming from the right. Any ideas? Its not the amp as I have swapped back and forth between my Systemdek IIX and the problem lies with the Thorens.
It has a Nagaoka MP-11 cartridge on the original arm, could it be a knackered cartridge near the end of its life?
Here are the pictures
I had a bit of a disaster assembling when I scratched the front of the plinth :oops: and will need to sort that out
I have the plinth sitting on 3 rubber Rega Planner 3 feet I bought off ebay
As I mentioned the base is preety deep and musical much deeper than my Systemdek IIX
