Verified PurchaseHighly recommended
Each came with a written test report and also checked for noise.
Thank you for the feedback. We invested in our own custom equipment because standard AVO type testers could not check for noisy valves.
Verified PurchaseMuch better materials from the OEM boards, and sounds just as good, but a lot quieter!
Hey thanks for the feedback. Looks like our efforts going well beyond just making a copy paid off 🙂
Verified PurchaseArrived safe and sound thanks.
