TOPPING PA5 II Destop Amplifier Fully Balanced Power Amplifier with TRS/RCA Input
Aliexpress UK
The only thing I did was open the amplifier and clean the input board because the input channel selector wasn't working properly. I cleaned the outside a bit but it still needs to be cleaned both outside and inside.

The SPEC RSA-717EX Integrated is a powerful 50w amplifier designed for vintage values using modern technology. Please research the in-depth reviews available to understand why this is such a special piece of equipment and rare opportunity. Some case marking is reflected in the asking price but operationally it is in perfect condition. The wooden side panels which the unit rests on show signs of wear but the front panel is unmarked. The company design goals for musicality and realistic sound reproduction are immediately obvious. As an example, a singer I am familiar with, both performing and in conversation, now shows the detailed character of his spoken voice in recordings.
