Hi!
We have several customers with Lampizator DACs who use the 300B after the major improvement in the filaments in January 2016. None of them have reported any issues. The tubes should be operated like any other 300B. Especially the 45 has a much lower filament voltage than a 300B. So use the 300B setting of your DAC
best regards
Thomas
