I have for sale a truly unique high end amplifier. The NAT Symbiosis SE is a 100 watt SE(T) where the T = transistor. What is unique though is that this is a hybrid with tubes for the input and driver stages and a SINGLE large industrial FET for the output stage. That's right, think of that big FET like it was a big 833 output tube because that is the kind of single ended power we have here. The only other companies I am aware of to have ever made a similar design was Blue Circle Audio (BC2) and the outrageously expensive Ypsilon from Greece.
The amp is massive, weighing a good 140+ lbs. (65kg) with a 45 lb (20Kg) power transformer!! 4 massive heatsinks (2 for the output and 2 for regulation) and 4 chokes coupled with 100,000 uF capacitance makes it work well into difficult loads (it is 4 or 8 ohm switchable...not output transformers it actually adjusts the power supply!). It is also fully remote controlled with a nice all aluminum remote. I also have the original shipping crate (big wooden one) and the owners manual.
The amp has many features including:
Class A zero feedback operation
2 tubes per channel for input/driver
Full regulation for all stages
Fully direct coupled, no caps or transformers in the path
Choke filtered power supply with 100,000 uF capacitance
adaptive bias for lower consumption when not used hard
Please see the attached photos to see this magnificent beast!
I will ship anywhere but be aware that the amp is very heavy and so shipping will not be inexpensive. I am willing to drive it around Europe to interested buyers.
