I also have globe 27s, they test strong but the noise is audible when playing. They are really microphonic. I wonder if anyone had used tube dampers with the globes. |

6BL7, never heard of it. I know it could replace the 6SN7 in our amps, but not too popular since these are quite rare NOS's. I think I'll follow your suggestion this time around too Last edited by Musica Amantem; 06-15-2017 at 08:30 AM. |

What dampers are you using? I'm interested in trying them myself.

The 6BL7 is like a 6BX7 with more gain. They are not expensive.

Sorry! Seriously, the amp works more freely and bass lines improve tangibly.

With my little Inspire, an SE EL84, a subwoofer is an absolute necessity. It produces little output below 70Hz. I roll in a sub at 100Hz on it. On my 17wpc KT88 HO, I run it into full range speakers and it does a good job through the lower bass. Not great, but with fair power, definition, and presence. A bit loose & warm, really nice with some types of music. But not as much slam, definition, and really deep bass as with a good SS amp. My speakers -3dB point is around 26-28Hz, so they can reach down real low. I don't usually employ a sub in this system, but I can and have.
Running either Inspire amp into any of my smaller monitors, I own bookshelf speakers from Focal, Von Schweikert, and Spica, I find that a well-integrated subwoofer can add a nice deep bass balance. |

I run 2 REL subs from the same era…a Q150e 10", and a Q108e MKII 8"…and since they utilize the amp's output it would seem there's plenty of bass generated by the Fire Bottle. Without the subs my mains are fairly flat to around 40hz (Sonist Recital 3s) and the amp gets to that area just fine, but with the subs it's sublime (sorry).

Bombadil: "I find that a well-integrated subwoofer can add a nice deep bass balance."
I used to do that, but a SUB that merely reinforces the full range does not have the same effect. Replacing those lower frequencies with the SUB alone, and allowing the amp to work everything else out without that burden, makes a tangible difference. I strongly suggest you try that filtering approach. |
