Has anyone compared tunsol of old against the modern type , I'm currently running a pair of ming da monoblocks , 6sn7 6sl7 and el34 power vale
jinvina 805 , I have replaced the new tungsol el34 with rtf and it has slightly more body and less edgy top end than the modern tungsol , its better I
think , I have never tried swapping the 6sn7 and 6sl7 , I have read that the melz is a great sounding valve , I have had most 12au7 12ax7 and like
the old rca and tungsol , finding mullard to coloured and lacking top end , I'm not a lover , but tend to like the usa type valves especially old tungsol
has anyone gone down this road , cheers phil.
