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

While we are on the topic of the Sutherland phd, does anyone know were to buy the blank cartridge loading cards? The places I've checked don't seem to carry them.
Willster, As far as I know, Acoustic Sounds is the main distributor here in the USA.

You can find thier site in the agon manufacture's alphabetized index, and contact them either by phone, or email. Ask for Chad, he will surely know, and can no doubt provide you with the Blank Loading Boards. Mark
I've already tried Acoustic Sounds. Sent several emails without a response. Finally, I called them and talked to someone who took my contact info and said they'd get back to me but never did. Since my last post I've been told that these boards are only available directly from Sutherland. Problem is, it seems to be impossible to contact Sutherland directly.

I'd also be VERY interested in service manuals and schematics but everyone I've asked assumes I want them because I need repair and just tells me to send the unit to a repair facility. I've been working on a design for an external supply utilizing rechargeable batteries but I need additional configuration details that a schematic could provide.
