Nikko TRM-500

1970’s Vintage Integrated Amp

One of the first of the Nikko amplifiers to arrive in the UK, this one is in mint (perfect) physical condition (see close-up pictures) and full working order. Designed and built in Japan in the early 70’s, this is a really sweet-sounding vintage amplifier.

Discrete design (so no nasty chips or IC’s), excellent built-in MM phono pre-amp with inputs for two separate record players, ‘Pre Out / Main In’ switchable - and many more facilities often found on Japanese amps of this era.

User switchable mains voltage (see picture 14), so this will operate in any country.
