Tron Seven Phono

David12

What i know is that TW has a lot of static problem with the motors. I know of my own problems and 3 others here in scandinavia.
All of us, got the same messege. It has`nt happend before!!!

Now you speak of it too. So i think that static problem is a cummon problem with TW`s motor......

I have had my motor and controlor replaced, due to static problems. But i still LOVE my Raven One :-)

Pierre,
Graham Tricker builds his TRON phono stages to order. The TRON Seven has been upgraded since 2006, I believe. Whilst having multiple settings can be convenient, the dip switches could possibly degrade the ultimate sound quality like any other connection/switch. GT can modify your TRON to suit other cartridges if you like, or upgrade your Seven to current specification. The current Seven phono range has several models including an ultimate model with separate valve regulated PSU, silver wiring, bespoke components etc (at a price!).
If you’re happy with yours, why change? I have had the same TRON Meteor preamp with on board phono since about 2003/4. I am really happy and don’t see any reason to change.

Very curious to know whether this static build up problem is due to the motor unit is housed on the table base. Hard to imagine the static is from belt to motor shaft, then the problem will be all over the place.

David, Pierre...me too (2 years ago)....and yes, I was the only one to suffer from this.

No problems since then, thank goodness.
Although they didn't appear to know what the problem was at the time I suspected static was the cause. Ever since I've refrained from incidentally touching the motor housing (just in case).

Static can be very destructive. I lost one of my (active) Martin Logans for 2 months because of it. The stators are effectively an external terminal and can be used to input static as well as output it. You would think that something that normally handles 5-6kV would be immune but it isn't.
The sensor circuit was damaged, which affects panel charging. The panel still worked ok but instead of charging in seconds took more than a minute to do so.

David, many thanks for your kind response. Hope your T/t problems are history now. :)

Resistive loading is really NOT a big issue when it comes to step up transformers. The bigger concern is the appropriate turn ratio and the amount of gain provided by the step up transformer. If your Tron has the right gain for the Delos, you really shouldn't have to be too concerned about resistive loading. Tron offers several gain options for their built-in step up transformer. For the Delos, as would be the case with MOST MC cartridges other than high output cartridges or very low output cartridges, the appropriate gas is 20 db. If yours is so outfitted, I would not worry at all.

A very good paper to read about gain and loading of step up transforms can be found here:
