nightyj · 20th December 2011, 10:21 PM

Up for sell is mono block amplifier with 300B. Input tube is JJ ECC99 it gives a lot more detailed and fast sound than 6SN7. Each mono block consist of 300W power toroid, 5C3S kenotron, ASC X386S first capacitor, choke made from output transformer iron followed by JJ power tanks. Power line for first stage is stabilised with tube which is the most important part in this amplifier and make it sound a lot better compared to the regular CLC power supply. Power resistor are Kiwame, anode resistors are Takman Carbon film for input tube and Takman Metal film for cathode bias. Cathode capacitors are silver tantalum military grade, interstage capacitors are Mundorf M between input and driver section and Jensen Copper foil paper in oil for connection between driver section and 300B. Output tube is Full Music 300B solid plate, loaded with output transformer from Gerd Reinhofer model 35.30. Volume control is made with 12 position switch with high precision nos Philips resistors which helps for the perfect channel matching. All the parts are matched. Output power is arround 5W, load of the 300B is 5K at 8ohm. Price for amplifier is 1800$ you can contact me at 00359896755833. Here are some pictures:

This is my GM70 tube amplifier. It is to heavy that is why I was not able to move it away from the picture, sorry for that.
