Due to a change of plans, I am selling this item. This is an unused, unpowered STAX vacuum tube driver unit "SRM-700T". I purchased it as a B-grade outlet item from Fujiya Avic. ■Product Condition • Unopened after purchase, and has never been powered on or used. • Refurbished / slightly scratched ■Warranty • I checked the contents of the x9000, which is also listed, and it seems that a postcard needs to be returned for the warranty to apply. Therefore, although the box is unopened, the warranty is likely not applicable for this item as well. ■Other • Although it is a new item in the same condition as unused, please purchase only if you understand that it is a B-grade item. ■Set Purchase Information (X9000 is also listed) If you purchase both items together, the total price of 786,000 yen can be adjusted to a set price of 778,000 yen. If you wish to purchase as a set, please comment before purchasing. The price will be adjusted on a first-come, first-served basis (no holds or reservations). ※ The set discount will be discontinued if either item is sold first. Thank you.
