Received my Ref 250SE amps
 

Hi,

I just received my Brand New Ref 250SE Amplifiers today. Before this I had REF 250 in my system and tried REF 75 and GS150 before buying REF 250 SE. Will upload some pics.

Now i have to go through long burning process.

Congratulations, beautiful amps.

Congratulations!

Congrats. I'll be very interested to hear your thoughts on the difference between the 250 and the 250SE! I plan to upgrade my 250's to the SE once my tubes are in need of a change.

Sure. I will hook the amp tomorrow and keep updating the thread.

Congrats! Look forward to your comments. And, be patient! Enjoy the journey to 600 hrs.

I wonder if one could use a set of older or "less desirable" used tubes, such as KT120s to break-in a new SE amp?

I look forward to your considerations VP, I think! :dazed:

I would think so, even tho a couple of resister values germane to the KT150's in the SE are undoubtedly optimised for the slight difference in draw, I would be surprised were the circuit to operate outside the safety margins of KT120, crank the bias by 10>15% or so just to be on the safe side!

However, as in all these matters, It would be advisable to seek the official line on this via Kal at ARC Central Command!

congrats!
am much looking forward to your thoughts and impressions as well.
