 Sound quality:


A similar electronic tube power amplifier, power amplifier, audio and mellow, sweet vocals, bass clean strong, free, strong sense of sound level, the overall effect is better than the quality of class AB amplifier.

 

1969 AMP finished machine parameters:

1 audio input: dual channel audio signal input;

2 audio output: a 15W+15W dual channel audio output;

3 working voltage: AC 220V  ( 110V version ,Need to be customized, about 7 days to complete .)

4 input power: 100W

4 input impedance: OHM 10OK

5 output impedance: OHM 4-8

 

The main materials are as follows:

1, the chassis: the use of all aluminum chassis, on both sides of the heat, the appearance of simple and beautiful (size 228X78X295MM, finished machine weight about 5KG)

2, power amplifier board: 1969 gold seal Gold Edition, symmetrical design. A full set of original gold seal Motorola (or ST) transistor (the tube must be used to seal the tube, such as the replacement of the new tube to replace the sound quality will be poor), the German WIMA capacitors do coupling (make up the lack of a high pitch).

3, high quality integrated power board & speaker protection board: ON Schottky barrier rectifier MBR20200CT rectifier, 20A current output, 2 35V 22000UF have a fever Panasonic capacitance, a total capacity of 44000UF. speaker protection, imported OMRON silver plated contact relay protection horn, no impact switch, do not add 1969 horn protection, when starting up capacitor charging current a few A, enough to damage the horn. No horn protection, switch machines have a serious impact on the sound of the horn, timid people switch to the ear!!! Bold, also easy to get the boot phobia.

4 transformer: 100W copper wire toroidal transformer.

5, volume control: the use of Japanese imports of original ALPS potentiometer.

6, the power switch: 19MM high quality metal with lamp power switch, feel good, beautiful and beautiful blue light ring.

7, the whole design is rigorous, the line after several improvements, no noise, no current sound, the whole assembly is good, the interior is very neat and concise.
