The disposal price has been reduced. Member prices are not applicable. 2025/9/16 sales price 148,000 yen ※The power supply specifications are different between the 2 units, but maintenance is performed according to the 117V specifications. Sufficient output is produced even at 100V. Maintenance includes replacement of 6550A4, 42 5ARs, 2 capacitors, 9 resistors, etc. 117V specification DYNACO's tubular mono power amplifiers are highly popular. The sleek, straight, and energetic sound that comes out of the small body is attractive. Combinations with Altech and JBL are a staple, and they make jazz and rock sounds powerful and full of realism. The color of the transformer is different between the two cars, and there are rust, dullness, small scratches, etc. appropriate for the model year (Oikawa Tetsuji)
Maintenance information: 2025.9.15 Maintained (all soldering around the vacuum tube socket and block capacitor terminals corrected, wiring to the preamp power socket was implemented, selenium in the bias power supply was changed to silicon diodes for preventive maintenance, electrolytic capacitor replacement on the bias power supply unit (2 pcs/Ch), lead wire soldering correction to the board, bias volume cleaning, soldering correction around the speaker terminal, mica Confirmation of capacitor insulation and capacity (Ch.A specific repair) US socket cleaning, cleaning, exchange resistors with different values from the circuit diagram due to resistors on the board (3 positive: 47k, mounting: 51k), replacing those synthesized with resistors on the board and matching the resistance values with 1 resistor (2 locations 1.5m and 270k), board pattern peeling correction (Ch.B specific repair) power supply and output transformer cover changed to 4 points, operation test)
Accessories: none
