Hi Chris, See http://www.leapsecond.com/pages/tbolt/power.htm and http://www.leapsecond.com/pages/tbolt/noise.htm I use a Condor / PowerOne HTAA-16W triple output linear. Technically it low on current for the +12V, but as full current is only drawn during warm up and the -12V is virtually unloaded, it copes well and is nice and quiet.

In the end I realised why connecting to the BT master socket with an extension cable to the router stopped the issues, yet connecting the original twisted pairs BT cable brought it back.... I had installed a Thunderbolt on the roof and its SMPS was behind a studded wall in my upstairs office, right near the BT jack, with the cable running *right* by. I *THINK* either the TB itself, its power supply that came with it from China, or just possibly a 5V SMPS I use to power one of David Partridge's divider boards, also next to the TB power supply is the culprit. The 5V SMPS is just a wall wart, but regulated and branded. I can easily find another, or even build a little linear supply for it. I don't think the divider board itself is the cause. However, I am unsure just what, and how critical, the demands of the TB are. Has anyone had this sort of issue with a TB power supply, or had cause to either find another, or find an alternative? I am not yet sure if the PS is a sealed up box, or if a repair may be an option. Any advice please? Thanks. -- Best Regards, Chris Wilson. mailto: [email protected] _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
