It's been maintained! This is a set of QUAD first transistor preamp 33 and power amplifier QUAD303. Both are well maintained, such as replacing condensers. The warranty is 2 years so that you can use it for a long time, so you can use it with confidence. A warm and thick sound that I don't think 40 years have passed since production. It goes well with European speakers, and you can enjoy a glossy and sexy tone. The appearance has a feeling of use over time, such as floating rust, scratches, and dullness. (Tomoho Asaine)
