Item: Image by Nelson Audio EL34 Power Amps (Mono blocks) Location: Melbourne City Price: SOLD Item Condition: Great working order Reason for selling: Space constraints /Simplifying system Payment Method: Pickup only (Melbourne CBD) - Cash only Extra Info: Punching well above their weight, Image by Nelson Audio are based on the Marantz 9 power amps. 75 watts output based on 4 x EL34 tubes and each unit weighs in at about 35kg each so I'm afraid local pick up only. These mono-blocks made a substantial difference to my system in terms of texture, resolution, speed, attack and the general warmth especially with vinyl source material. Priced to SELL to clear up room in my limited space so please, no negotiation. Since purchasing this, I have had the switches and new tubes fitted with about 100 hours on them. The units have some very minor cosmetic blemishes as indicated in photos and functionally they are a joy to live with.
