Tube Amp Archive

When you'll try it tell us your opinion about it. Finally I bougnt Eminence RAMROD (100dB) and now it sounds really great. Is louder and has more bottom because (I suppose) low frequency starts form 80Hz instead of 100Hz with Legend. Thanks to your mod Mikka I have great full valve combo for only 2...

Yes, it would be great to place Red Fang but it is twice more expensive I paid for GA15

I found that Eminence Legend 10516 has 100dB, difference between 1058 is only resistance.

Unfortunately there is no Govervor 10"

If the efficiency rating sesitivity (SPL) is lower, it will take more power to reach the same volume.

Hi,

Do you suggest the stock China speaker has better performance than Eminence?

Yes it's true, running power tubes with less voltage get down power with more class A sound result, but in the same time the sensitivity of your new speaker is not particulary high.

Thanks for quick answer. In a few words, what can I do to get more power?

Hi ! Here is how I upgraded a friend GA15. It's here. Hi, I'm new on board. Thanks for the modification. I did it this weekend and the GA15 sounds great, I changed also tubes and speaker for Eminence Legend 1058 but i feel it was louder before modification. Can that be true? best regards, Adam.
