@romad I know the Lenco GL 75 TT, through ownership of the GL 75 and through hearing it in use in multiple design through being very socially active as a Lenco Heaven Member and having friends who were doing substantial work to the GL 75 models. I have no doubts that I have been demoed designs for GL 75 mechanics and very will thought through Plinth designs, that will comfortably be equivalents or even surpass the designs put in to the market by the individuals who have exposure for the marketed goods.
After all the experiences had of both the GL 75 and prior to this the Garrard 401, I was to eventually becoming an owner of a PTP Solid 9 > Upgrade Bearing > Custom Speed Controller. I was to learn the PTP Solid 9 with the added supporting ancillaries is the best of the GL 75's I was demoed, which was the deal maker for me.
In today's money the PTP Upgrade Bearing adds nearly $400, and the bought in Speed Controller adds nearly $1.6K as a further cost. A 20% reduction will be nearer the prices I paid.
I enjoyed the PTP Solid 9 for many years, and still do own it, but is certainly a Superseded TT.
For less than what I paid for the PTP Bearing I acquired a Japanese Vintage Model DD TT, being a SP10 MkII and this purchase extended into making purchases of a selection of different brands of JVDDTT's.
The SP10 MkII became the model of interest to be first to get the full overhaul.
The MkII has been fully overhauled electronically, has a custom design Speed Control and has had the main bearing modified as a design. Where all works undertaken has been by one of the UK's most renowned overhaulers of JVDDTT's with the SP10 MkII being there model of real interest.
The same TT over time ended up mounted on a Panzerholz Plinth.
This experience of the MkII and the extremely good impression made constantly, was instrumental in my seeking out and learning about the SP10 Mk II Kaneta design, of which I own a model today, albeit being out on a long-term loan. This design also ended up in a Panzerholz Plinth.
I can now sell on the PTP Solid 9 and the Speed Controller to reimburse funds outlaid and still have a nice-sized wad of £'s left to play with.
Through being socially active with my audio interest, I also get the chance to hear the SP10 R in use regular.
The SP10 R owner owned a Linn LP12 and a very well-designed Lenco GL 75 prior to purchasing the R. The GL 75 was supported by my Speed Controller when the R was compared to the already-owned TTs. The R superseded the GL 75, and the R and LP12 still remain today.
Today, the LP12 has a Custom design Speed Control, a later design bearing, and a custom-produced keel.
The Linn LP12 with a custom-produced keel, which, since being in use, has encouraged claims to be made stating the LP12 is notable for being very attractive as a TT. There is plenty being mentioned as a result of demos that suggest the R, has a competitor not looking to be needy.
Buying a Speed Controller is an expensive option, especially when a TT can be purchased for less money, and when overhauled and re-plinthed, will possibly still be cheaper than the Speed Controller's new purchase price.
Whether one feels the alternate Drive to an Idler Drive is their preferred experience is one I can't comment on, but my experience regarding the subject is indelible and very easy to produce a report on.
