the real difference between NOS 5Y3 or any NOS tube for that matter and a new one is that the newer ones usually are not what they are labeled. a russian 5y3 equivalent tube was not the same as a real US made one. most tubes you can get now are from russia or china and follow the russian specs for the closest tube to what they are labeled. also if you want to try a solid state rectifier but dont want to chop up your amp you can find solid state rectifiers on ebay that plug right into an 8-pin socket.
