Reporting question for Vacuum Tube - 300B, Valve Art

Vacuum Tube - 300B, Valve Art

Hi. Wondering two things please 1 is there a warranty on these and Do you have two quads that match up pretty close. Each mono block requires four and if so do you ship them all together? Like combined shipping? So I guess really that is 3 questions. Thanks

All tubes have a 90 day warranty. We can provide two matched quads providing we have them in stock at the time. All international customers pay actual shipping.
