    This is just a heads up on the cheaper Chinese tubes that are being sold today.
    This is my own picture depicting an issue of a 572 tube that is too long for one of my amps being its vertical mounted, it actually grazes the top cabinet. This equals DANGER.. This is from a first hand experience. Measure each tube even if they are a matched pair. This is just a heads up. Click on the picture and see for yourself.
