Tron Seven Phono

Hi there!

I have a standart Tron Seven Phono from 2006.

I´m am quit happy with it, i think........ I havent tryed others on my current setup, so i dont know "better".
I have read that many others is quit happy with the Tron Phono, so why shuldnt i be?

But i have the past mounth been thinking about what it can and can not. It sounds great with my Lyra Delos, but the Tron is a pluk and play phono. There is NO settings........ So how can i be serten that i get the full out of my cart?

Can any explain me how the Tron Seven Phono works and why it has`nt any setings. Other Phonos are packd with different settings so you can set the recomanded load or any other settings.

That why i`m beginning to questions the Tron Seven Phono..... But do i have any reasent to question it???

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:

Moonglum Pierre. There is an easy fix, just earth the motor. Perhaps Thomas will do that to all the Ravens now.

I agree that it is a great table, best I have had and it is taying forever.

Even if there are problems, a company and it's distributors providing that good a service, is reassuring.
