This is a Hi Fi setup of a Trilogy 902 preamp and 2 x Trilogy 958 mono power amps. This was the very top of the range hi-fi that you could buy at that time in 1994. The chap who bought it, sadly died that year and it was immediately put into storage. It has been in there for 20 years, hence it is a bit tarnished and needs a really good clean. I haven't tested it with speakers, but the valves light up and LEDs are on. One of the smaller valves might be blown as it looks a different colour to the others. Some of the bigger valves had the plastic tab missing, but the shape of them is still there so you can tell which way to insert them. This will be for collection only, as it is extremely heavy, but delicate at the same time.
