This is the largest amplifier Heathkit ever offered. Includes manual, schematics, illustration booklet, and original receipt. All paperwork is in excellent condition. The amp uses two line cords to protect the system preamplifier from having to switch the high currents required by the amplifier. It is in great operating condition and looks great too. The builder was a talented engineer that took his time with his builds. I will remove the power transformer prior to shipping and pack it separately as the manual recommends. I ship FedEx ground fully insured. Also, I wanted to note that one of the speaker terminal plastic coverings is cracked.
