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???

Moonglum, Speed control went haywire,it stated revolving about 500RPM, very alarming. evidently it can be due to static build up, though it has'nt happened to TW before. So Thomas sent a new motor and controller free, worth over £1000 and Graham fitted it free. You can't say fairer than that. graham earthed the motor, so it can't happen again.

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. :)
