Silbatone L-106 power amplifier is very interesting Single-ended Pure Class A tube amplifier, with 10W output per channel. It uses 45 output tubes and copper output transformers with permalloy core.
Very unique feature is it’s “hybrid” design that combines a solid state circuit, that supplies current in order to bring much higher damping factor and power output.
The result is a refined tube sound, full of musicality, but with lots of drive, bass impact/control and the ability to drive more difficult loads.
