    Hi

    I blew the tubes on my V4B so I need new ones. I read all about 7027A and how the new ones are not so good. Also about how good the 7581A are for this amp but almost imposible to get and expensive.

    Finally I was deciding on 6L6 winged C until I came across this site:

    https://www.watfordvalves.com

    They claim to have 7027A as good as the original ones and also they carry 7581A that are as good as the discontinued ones

    Does anybody can give me any input?

    thx

    You are putting too much thought into this. Old tubes vs newer made tubes are hardly any different. Blind test the same amp with different tubes and you most likely cant tell a difference.

    Wouldn't quite go that far with it, but yes, new tubes have gotten much better and the differences are often quite subtle at best, though not always. I'd at least give them a shot. Beats paying ridiculous money for NOS or rewiring your V4B for 6L6's.

    A quality 6L6 will plug and play in a V4B, no mods.

    There was a time when the 7027A was in really short supply, for that time period it was suggested that one could use a 6L6GC as a substitution, here is a link that will explain the differences between the 6L6GC and the 7027
