Rega Planar 1 Plus

[davidf]

For mechanical reliability - there are Regas that have been around for 40 years that are still with us. I doubt any Crosley bought so far will be around by the middle of this century...

Point taken but there are working Garrard AT6's that have been around 20 years longer, so their argument it was for reliability reasons doesn't stand up to scrutiny. It was omitted just for cheapness, and sold to gullible hifi enthusiasts as a deliberate simplification to improve sound quality.

True, but then Garrard (like most manufacturers back then) built things properly - I was more referring to the mechanical speed change that is built into many modern day decks, mainly the ones filled with 5,000 cogs that are made of the same material as the turntable.

But those original Rega Planar 2 and 3 turntables provided a lovely, clear balanced soundstage.

Hmmn. Just read my post further up in the thread how to do this, or google 'variable frequency synchronous motor drive'

I am aware of frequency reclockers. I don't really call that 'easily'.

I have no idea what a 'frequency reclocker' is.

I am not suggesting you need to design a VFD from scratch, a nice man in Shenzhen has done that for you. What I had in mind was something along the lines of:

While it is not really ideal for the job, (and I wouldn't suggest you buy one to change the speed of your Rega) it gives you an idea of what is available. What's not easy about that?

Edit: I had another look at the VFD on eBay. The blurb doesnt say it, but I suspect it is designed for a 3 phase motor given the wiring diagram. So not suitable at all for the Rega, but I hope it illustrates my point.

What would that device be designed for? Just curious!

I realise it's one of your long-standing and oft-repeated gripes but it's not ever going to go away while people keep buying these kind of turntables by the droves. If I was buying a new budget turntable I'd probably gravitate towards something like an Audio Technica LP5 rather than one of these formica-worktop turntables from Rega and Project, and this is at least one of the reasons.

+1

If you bought a turntable that doesn't suit your requirements then bigger fool you.

Speed control of AC induction motors was the holy grail. In the days before electronic control, it was very difficult to change the speed of an AC motor. In the 60s my Mother had a Hoover 'keymatic' washing machine that had the most convoluted reversing motor with directional clutches, multiple belts and a step down gearbox to control drum speed. These days the tune your washing machine plays to you as the drum speeds up and slows down is the 'Variable Frequency Drive' chopping away. You find these devices in everything that needs to control the speed of a motor - from a Tesla car to a washing machine to your commuter train.

In a washing machine, the drive will be part of the control electronics and not a separate box like the one I linked to. The stand alone box would be more suited to low volume industrial machinery, production equipment and so on.

Thanks, Andy, that’s very illuminating.
