This amp replaced the Klangfilm KL-V502
EL34 amp in the the Eurodyn racks. Output power is 25 Watts into 15 Ohms.
The output is transformer coupled with a very good output transformer.
Beside the sonical qualities of this design, it is very stable and
protected against shorts. There are very few transformer coupled solid
state amps for HiFi and these are highly regarded.
The output stage works in a classic
2N3055 design and the regulated power supply uses another
transistor of this
type for regulation. As used as direct replacement for the KLV-502, this
amp also offers tone controls and a high quality input transformer.
