Hi Turnip,
my English is not the best ,but I will try to explain.I'm talking about the microprocesor board eprom software.I own this Seleco SVD500Plus ,and it's happened to don't start the tubes.The diagnostic said the problem is with this eprom sw. the eprom was overwrited with the sw downloaded from the Seleco400+.Now the PJ is usable ,but is not the same as was before.So ,this is why I'M here.
