Sale Price: £3,375.00 Original Price: £3,500.00

Melos Triode Plus Mono 400 Series Valve Monoblock Amplifiers – 240V (Pair)

A pair of Melos Triode Plus Mono 400 series valve monoblock amplifiers, 240V version. These are powerful high-end tube amplifiers from the respected American manufacturer Melos Audio, known for their dynamic sound and excellent build quality.

Both amplifiers have been tested and are fully working. They present in good overall condition for their age, with some cosmetic blemishes and marks consistent with normal use, as shown in the photos.

The original user manual is included. Notably, on the front of the manual the printed “MONO 400 GOLD” has been replaced with “402”, which may suggest these units were upgraded to the 402 specification at some point. However, no documentation or further evidence is available, so this cannot be confirmed.

A rare opportunity to own a powerful pair of classic Melos monoblocks.
