Lyra Helikon and Phd owners please

Hello my friend, I have privately emailed you, and the advice-suggestions which were given to me by Chad at Acoustic Sounds.

To just give a brief rundown here, so that it may benefit future PhD owners in the Archive, Chad recommended to check that all batteries are properly installed on thier respective Battery Holders. As you know, these Battery Holders have to clamping force of a Pit Bull's Jaws, and thier could be the possibility of one, or more not being properly positioned on the Holder.

As I added in my letter to you,the other possibility of tired Batteries. Remember that previously, you had issues with the Unit staying on for very long periods, you mentioned for periods of 24 hours straight on occasion.

This could have possibly exhausted your Batteries somewhat, even though Sutherland claims a 700-800 hour Battery Play Life on average.

The other variables, are what brand-quality of Batteries you used, high enviornment temperatures where you live, age of Batteries, etc.

I recommend again trying another 16 fresh Batteries.

Lastly, I am unsure if Gain at the boards Plays any influence of increasing-decreasing the Sentry's sensitivity. Apparently Chad indicates that Battery quality-voltage does.

Again my friend, I hope this helps you, Mark

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.
