Vacuum tube amplifier, integrated amplifier, vintage, parts, audio, analog

Please consider this item only if you are able to replace parts and perform maintenance yourself, as a circuit diagram is included.

I believe I purchased this amplifier from an amplifier specialty store in the Kansai region several years ago for around 70,000 to 80,000 yen.

I haven't used it much, so I tested it for about half a day before listing it, confirming that the pilot lamp lights up and that sound is produced from the speakers.

The vacuum tubes are 1626 and 12AU7.

There is some crackling noise when turning the volume knob, but no noise when it's fixed.

The RCA connectors may not make good contact with my cables. This could be due to my cables, but the sound works fine if I wiggle the cable connectors.

Although a circuit diagram is included, some parts have been replaced with audio-grade components, so the values of the capacitors, etc., in the actual unit may differ slightly from the diagram.

The coupling capacitors are still in the aging process, I believe.

The vacuum tubes will be removed and packed separately.

I will pack the unit with bubble wrap, but there is a possibility that solder joints may come loose due to vibration during shipping. Please consider purchasing only if you are able to solder.

Due to the nature of the product, I may not be able to provide support other than for shipping accidents.

Please purchase only if you understand the above conditions and that this is a used item.
