Lyra Helikon and Phd owners please


I have recently upgraded the cartridge from a Sumiko Blue Point 2 to a Lyra Helikon on a Rega RB 300 arm and Michell Gyrodec TT. The phonostage is a Sutherland Phd.With the Sumiko cart getting the Phd to wake up was a non issue :gently stroking the stylus, perhaps once or twice was enough and the Phd was ready to sing. With the Helikon nothing seems to work other than letting the stylus ride on the lp for 30/45 seconds.This is bothersome but not a big deal.Have tried setting the sensitivity control on the Phd( counter clockwise to increase it)but this only results in the yellow light (indicating that the cart is searching for a signal) coming on in the middle of a record and refusing to go off.
I wonder if any Lyra/Phd owners have encountered similar issues and what the possible soloution could be.
Many thanks and cheers

Mark, My mistake as well! I see now that the Installation Instructions that came with my standard Helikon states .5mV output.
Thank you again for the clarification.
This is such a wonderful forum which has helped me more times than I can count. It's a great feeling when you can sometimes return the favor to others with sound, helpful advice.

I hope that my educated "guesses" will help "sunny", so that his Phono Amp gives him the pleasure that it should bring. I reckon we'll know in short time.

He's on the other side of the Globe from me, with me in the Southwestern US, and him in New Delhi, India. Mark
Hi Mark/All,
Many thanks for all your advice/suggestions. Immediately after installing the Helikon, there was a big drop in gain. I had to crank the gain settings on the Phd to max, ie 60db. Currently(sic!) and I don't have any issues with loudness or gain. The best that I have managed to do with the Helikon is to reduce the wake up time to around 23/30 seconds or so.If I tweak the sensitivity further the yellow light stays on which I assume is not good news for the power management system in the Phd.
As I said earlier this is bothersome but only for the first lp.The cart loading is set at 47k ohms as recommended in the Lyra manual.
As an aside the the Helikon sounds heavenly.
Wow this is a great feeling sitting halfway across the globe knowing someone somewhere is concened and willing to invest the time and effort to help find a solution.
Cheers and bye for now.
My friend,
I have written to you privately, and as I mentioned, I will try contacting Chad at Acoustic Sounds for you ASAP, and try getting accurate information, if Gain plays any significance-coorelation to the Sentry's Sensitivity.

Since you a 1/2 world away in New Delhi, it will be much easier, and less expensive for me to make the callto him, and I will inform you of the findings-opinions from Chad.

It is hard for me, or anyone else to determine if 60db through the Sutherland is properly adequate for the Lyra Helikon? perhaps other Helikon owners can comment of what gain settings they seem to be typical for the Helikon.

I could drop my friend Tom Back a letter, as he's using his Sutherland PhD with a Clearaudio Master Reference Table, and a Lyra Titan, which I "think" has the same output as the Helikon? (Seems darn tough getting proper spec info on these Lyras!)

Perhaps he can remember what gain settings he's using with the Titan, and if he had to resort to the High Gain Boards? Mark
Hi Mark,
Many thanks for all your help and advise. As I mentioned in an email, I not sure how a higher gain board will help given that the output of the Lyra is fixed at 0.5v(I checked the manual).A higher gain setting on the Phd will only make life easier for the main preamp(CJ CT5).
Cheers
