DIY kit, SE class А tube amplifier, cascade structure with a capacitive connection between the inlet and outlet tube.
The input amplifier is 6Э5П a lamp with a huge potential and opportunities, and the output G807 ( Г807 ).
Regarding power: It is made with two separate independent „circle.“ NOS Svetlana 5C4S a very good rectifier tube. For each „circle“ filtration is standard for this type of amplifiers “CLCRC”.All components are considered to assist and better efficiency of the amplifier.
Choke – 2x8H – 200mA (150 Оhm)
Power transformer is made from Bultraf made with high parameters and additional requirements to better performance and results. http://www.bultraf.com/index.php
Output transformers:
High quality, Italian, silicon steel sheet for transformer cores.
TECHNICAL SPECIFICATIONS:
Ra = 5K / 4Ohm; 8Ohm
R1 = 270Ohm
L=10H
Ls<15mH
Ia(max)=80mA
Sockets: The package for each lamp – 6 pieces.
Lamps: The set 2х 6Э5П , 2х Г807 and 2х 5ц4с.
Filtering capacitors: Mundorf, F&T, Simens, Roe and ather depending on their purpose.
Resistors: Mills, Kiwame,Tesla and ather depending on their purpose.
Volume control 24steps: One piece 25 Kohm included in the set. https://momchil.wordpress.com/#jp-carousel-417
As a whole amplifier is the result of a lot samples and attempt gained over the years.
The output power is close at 7W of channel.
Power supply: 230-240V 50-60Hz 280W
I offer it with diagrams and parameters .
