Maintained including 24 resistors, 4 capacitors, and 2 silicon diodes replaced! It's a rare 100V specification this time too! 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. There are scratches, rust, etc. appropriate to the model year (Oikawa Tetsuji)
Maintenance information: 2026.1.7 Maintained (all soldering defects fixed. Replace deteriorated parts (12 1/2W carbon resistors, 12 1W carbon resistors (partially replaced with metal oxide film resistors), and replace 2 750pF phase correction capacitors. Preventive maintenance (replacing selenium rectifiers with silicon diodes, replacing 4 bias electrolytic capacitors) bias volume cleaning, and cleaning of MT tube sockets and input terminals were carried out. Operation and characteristics have been confirmed as a 100V specification product (8Ω resistive load output 52-55W)
Accessories: none
