300b get set go problems

2nd harmonics for the masses

300b heater

Postby chopdr230 » Thu Oct 02, 2008 1:09 pm

I am going over th voltages again and the 300b heater is at 8 volts . I installed te corrected resistors for r19 and r20 is 8 volts to high ?? if so would that cause the over driving distortion ? I have 2 new tubes to try but im scared to put them in now . Thanks so much for your help AL

I put the new jj tubes in and the heater voltage went down to 5.2 and it sounds fantastic so it was the tubes not the amp . Thanks for all the help AL !!!!!!!!
