For sale: GPC-TQ, manufactured by Voltampere. This is a clean power conditioner, a must-have for any recording studio with good equipment. It needs no introduction. This is a discontinued older model, and it has a 120V step-up function that the new model doesn't have, making it very convenient. I think the price will continue to rise in the future. I no longer need it due to equipment changes, so I hope someone who needs it or is looking for one will buy it. Operation has been confirmed. There is one stain on the top panel (see photo). Accessories include the instruction manual, power cable, key for step-up switching, and rack mount ears. There is no original box, but it is a very heavy item, so I will pack it carefully for shipping. Hand delivery is possible in the Nagoya city area. In that case, I will discount the shipping cost, so please comment. I am also selling this on other sites. I will remove this listing as soon as a bid is placed.
