Well, for me, selling a BS line and calling a matched quad would cost them a customer. Sad thing is that most folks are quite short on measuring equimpent. If they challenged my measurements, I would have responded with a demand for their test proceedure and match criterea. If it did not meet their spec....God help them.
thanks for the warning, for what it's worth for me...I don't do much volume in the traditional valve market.
cheers,
Douglas
