I have a Ming DA MC34-A07 SE Integrated amp which I am more than happy with.
The rectifier tube is a 274B. Does anyone know what replacements are available?
I have seen a few amps with Mercury vapour and Argon filled tubes. They look cool and would like to use one in my amp. Is it possible to plug and play with such tubes?
Cheers
Mike
