ELISE Stereo single ended

ELISElise webE Stereo single end 520B/300Bxls

Since we had gone back to less power single ended output designs for all the right reasons, we now had to search for more power from our single end designs.

The answer hence was in the new valve 520 b or the equivalent 300Bxls [email protected] watts.

“Musicality” is sometimes used as an excuse for shortcomings in detail retrieval and dynamic’s, this amp has both, the ELISE excels in these and other areas.

Again like the Diavolo same topology but with solid state high current power supply incorporating 2 pye filters and a choke filter for left and right channels.  

Also fitted our unique Sentry Circuit.

16 watts Triode with split bobbin multi section output transformers 4 and 8 ohm taps, 0 feedback speaker 89 db and above required for best results.
