Report Review for product Vacuum Tube - 6CA7, Electro-Harmonix

You are reporting the following product review:

I've used this output tube for years in a Hiwatt DR504 head and they hold up very well and sound good. A friend also uses them in his Sovtek Mig 60 amp with similar results. For me the EH output tubes have been very good durability wise but sort of hit and miss soundwise the 6CA7EH is a hit.
