Dynaco ST70 poor bass
Hi everybody, I have a pair of ST70 as mono driving my JBL Jubal L65
speakers. I´m not satisfied with their bass response, 500Hz bellow... it seems that its very weak... what can be done to really resolve this problem? or the ST70 is only good with de mids and high? |

If it is connected up and working properly, and you are still not satisfied, then you may wonder what impedance your speakers present at the frequencies you are unhappy with. cheers, Ian |

Dynaco ST70 poor bass
How is the bass response with only one channel and then the other? How
do the output tubes check out? Are the coupling caps original? Is the filter cap new, or in good shape? How about the rectifier tube? Many things can affect the sound. My ST70 has great bass with the original cap amounts, plus another 20 or so Uf wired across the output tube filter cap.
