Amplifier is in immaculate condition. No issues period. Less than six months old. I have all original boxing, all original paperwork, and it has upgraded pre amp tubes. The amplifier underwent a complete Skunkie Design Modification bringing its performance to a another level comparable to amplifiers costing five times as much. I have included a Skunkie Design modification list. This modification can be viewed on youtube. Its an in depths modification that must be seen to be appreciated. The amplifier is basically new...upgraded, and ready for use. The 300b tube amplifier is known as the Holy Grail of low wattage tube amplification. It boasts 8 watts per channel......so please keep in mind that a very sensitive speaker will mate with it nicely. Lesser sensitivity will result in pooer performance in terms of bass control and overall volume levels achieved. It drives my Usher CP6311 Speakers well....but I do not listen at high volumes. Keep in mind that the amp delivers 8 watts per channel. Again, I have all original packing, paperwork and of course the Skunkie Designs checklist. Amplifier will be double boxed for safe transit. It comes from a smoke free/pet free home. Thank you for your consideration. I ship to lower 48 only.
