classe twenty five and classe fifteen

willmacc6 posts09-28-2018 1:31pmIf anyone knows the answers, wd be much appreciated.
What’s the wattage consumption on the 25?
And do they produce alot of heat?

Classe DR-25 a very nice reliable amp, sweet and never in your face, a little boring.
They run factory spec 22mV across their .27ohm emiter resistors, around 10watts Class-A per channel at idle, warm to touch.
I raised that and got better sound, so the heatsinks after an hour of idle at 28c ambient were just uncomfortable for the palms of my hands after 6 seconds around 50c, this was more like 35mV across the .27ohm emiter resistors.

Mains fuse ratings are
100v-120v 12amp fast blow
220v -240v 6amp fast blow
This is not indicative of the power consumption but more the inrush current to charge the power supply caps.

If anyone wants the service manual PM me with your email address. I’ll send it out once to the first one, but you must send it to others if they want it here on Audiogon.

IMO the Classe Omega Reference monoblock amps are still the best sounding and performing amplifier Classe ever made to date.

Thanks guys. The model I saw is the later 25 (without DR) ie after founder was stitched up and booted out.

So I take it thats's 25w consumption at standby or idle? And then with any signal/volume its the full class A monte, no matter 'watt'

The 25 in the DR25 is short for 250w into 8ohms, nothing to do with power consumption.
