We support and service all products we've ever made. Owners Manuals are available; email us your model and serial number.
Shipping items to us -- Contact us for our ship-to address prior to sending anything to us. You will need a RMA number from us; we will need a Tracking Number from you; Shipping Insurance is mandatory; please carefully verify that our correct ship-to address appears on all shipping receipts and labels affixed to packages sent to us. Triple-check the address. Items sent to incorrect shipping addresses can be lost. Use the original packaging to prevent damage during shipping and to avoid replacement cost. Bubble-wrap, air-cushions, foam peanuts and flimsy boxes are cheap but can end up costing much more.
Terms for warranty repair service or additional work -- All shipping and insurance charges, customs duties, etc., in both directions, are the customer's responsibility. For repair/returns, customer should use the original box and original packaging materials to prevent damage during shipping and to avoid additional cost for replacement box and packaging. If necessary we can send an empty shipping box and packaging materials. Any loss or damage incurred during shipment in either direction is the sole responsibility of the customer to rectify with the carrier. Any necessary parts for repair will be invoiced together with shipping and packaging charges. An initial Estimate / Work Order / Proforma Invoice can be provided to customer upon request. We prefer Fedex, UPS, USPS, DHL/other in that order. Customer may arrange for pickup by alternate carrier, but we must be alerted prior to pickup date with approximate time and carrier service.

MADE IN CHINA means "offshored to be made as cheaply as possible. Your purchase helps encourage other companies to move their production to China, whose government may eventually choose to nationalize (take over) all of it in the future, leaving the rest of the world enslaved to China. Communist governments are evil, but not stupid, subsidizing labor costs today to help gain control of the world's means of production tomorrow. You've been warned."
We sometimes receive local requests for service of miscellaneous audio equipment.
