At this time, we do not sell to online tube vendors.

If you are a tube amp manufacturer, we can provide OEM price for factory matched pairs only. Please provide your business license information and use the contact form to contact us directly for a quotation. Minimum quantity applies to commercial orders.

All sample orders are at regular retail price – once you are satisfied with the quality, you can proceed with a commercial order then we will retro-apply the discount to your sample order in your new invoice.

Thank you for your understanding.
