Sorry to see this a little late. The PSU runs at 160 mA, so you need 2 x 160 mA = 320 mA minimal. You need 34 Volts on the regulator input (or a bit more, up to 40 Volts will be o.k.). The power disipation will be 34 - 24 * 320 = 3.2 Watt minimal ans 40 - 24 * 320 = 5.2 Watt maximall. More information can be found in message 5650 Mpp.

Regards,
Frans.

Alfred, The 6 Volt's is the minimum value, for absolute top performance I would like to see a bit more (10 Volt's would be nice). P.s. I am a bit late also

I worked as a repairman too. That was in the 80th in the High Tech industry.
We made power supplies for Sputtering up to 90kW. That was not only frustrating, partly because there was no complete documentation ( specs could change in a minute and Engineers left by the week ), but it was also dangerous because i had to short circuit them to test them for safety. That was with a 2m long Bakelite "Arm". The sparks i made that way could be a meter long.

Maybe not as dangerous as living in Japan today. I was just skyping with Stig Björge when i witnessed a 5,3 earth quake right in Tokio. The epicenter was only 30km away, but 620km in the ground. No person was serious hurt, thanks god.

Maybe that does not belong here but i designed an analog filter-buffer that comes behind the new compact DA converters from ESS and Burr-Brown that have inbuilt Opamps and can be used without anti aliasing filters. My filter-buffer is based on coils so it is inductive. I thought that putting a filter in series is better then shunting the potential junk over 20kHz to ground. It is of the aperiodic type so it is a bit softer then Bessel to have a good time domain behavior. The buffer is the same then in the new Paradise but build in SMD by Euvl and his team. I am looking forward to test it in my system.

Update: The numbers above for power consumption are the minimal's the maximum's are (when the RIAA is disconnected) 34 * 320 = 10.88 Watt or 40 * 320 = 12.8 Watt.

Frans.

Last warning to ATL lab from Brussels :
Reduce your power drain for your whole High End Audio chain to under 20W !

We will debate this, and ask for 20W per qubic CM ... or else ... My friends at the ATL say, 'The Borg' are never far away
