This is the Luxman luxkit A3600, a famous model.
This amplifier is a KT88 push-pull specification A class power amplifier with an output of 30-50W (8Ω load resistance).
The circuit has evolved from the A3500 and A3600, with the first stage being KT88 EF86 (Sovtek made) and the driver stage being 6AQ8 ECC85 (Matsushita made), making it highly reliable.
It seems to have been maintained once in 1995, and then maintained again including a review of the circuit.
Specifically, the main capacitors are Nisshin's audio laminated metallized polyester film capacitors, the smoothing capacitors around the power supply are ELNA's Cerafine, and the bias volumes have also been renewed.
Everything works as should. All inputs ,switches, controls have been tested before listing . It's Japanese domestic version AC100V 50Hz/60Hz.
Cosmetically all in good shape. Reducing my audio collection.
