Model: Classic 6N1+6P1 3W*2 stereo power amplifier finished board with 6E2 cat's eye indicator circuit
The finished board contains 5 tubes (two for Shanghai 6P1-J, one for Shanghai 6N2-J, two for Shanghai 6E2
Size: 200MM*110MM, board thickness 1.6mm, double-sided tin-sprayed board, copper thickness 1 oz.
The filament is powered by AC 3.15V-0-3.15V, all ground wires are grounded at one point, and the noise floor is extremely low. If a choke coil is used, the low noise is basically inaudible.
The finished board is connected to the power transformer and the output transformer to work.
The finished board contains 5 tubes (two for Shanghai 6P1-J, one for Shanghai 6N2-J, two for Shanghai 6E2
Power transformer (No. 764503) requirements: 220V input, output: AC: 230V-0-230V 100mA, 1 set of 3.15-0-3.15 3A filament input voltage.
Output transformer (No. OP573001): EI57*30, output power 5W, output with 4 ohm-8 ohm tap, 3 clips and 2 windings. Although the power of the whole machine is small, the vocal effect is very good, and it is a good product to hear the ear oil.
Mainly using imported components to assemble:
RF107 Fast Diode Full Wave Rectification*2
330U/400V Japanese brand electrolytic filter*1
220U/400V Japanese brand electrolytic capacitor secondary filter *1
22UF 400V Taiwan electrolytic tertiary filter*2
Hong Kong TE MKP 0.22UF Copper Foot Film Interstage Coupling Capacitor*2
Metal Film Precision Copper Pin Resistors
Silver plated ceramic socket
copper pin terminal
The components on the board and the electronic tubes can be welded on the same side, which is suitable for installation in the chassis. We call it the positive welding method. It is also possible to weld components other than the electronic tube on the reverse side, which is suitable for protruding the electronic tube out of the chassis. We call it the reverse welding method.
