Luxman luxkit A3500 vacuum tube amplifier power amplifier Custom used. This is a Luxkit A3500, but it is different from other A3500s. First of all, as you know, the OY-15-5k is prone to disconnection, so the transformer has been replaced. This time I used CSZ-15-5k, which is made by Lux and has the same shape.It is a good transformer with similar sound quality, UL connection, and does not spoil the appearance. In addition, we replaced the MP and OIL capacitors, which were gradually becoming suspect due to age-related deterioration, with new film capacitors.
All diodes were also replaced with new ones. The primary input of the output transformer has been replaced with an additional 100 ohms to prevent overcurrent. The circuit has been restored with a lot of time and effort.
Basically, we have faithfully followed the original circuit diagram. However, due to the secondary terminals of the output transformer, only 8O and 16O are wired. The tubes used are three Sylvania 6GC7s and a matched quad of GT EL34s. The 6GC7s can be replaced with 6FQ7s or 6AQ8s without circuit modification.Because of the fixed bias, it is necessary to adjust the bias using a tester when replacing the EL34s. As expected, the preamplifier-power amplifier compatibility between Luxman is outstanding and handles all genres with ease. 465mm (width) x 168mm (height) x 206mm (depth) Weight Approx.
