Jj tubes/valves.

Post by Philbit » Thu May 20, 2021 5:14 pm

Hi all newbie here.I currently own a Mesa Dc-3 and a Rectoverb 25.I’m wanting to reduce the harshness on the gain channel by using something like a 5751.
I’m located in New Zealand so only have a limited supply of brands of tubes here.So my question is can I use Jj’s in the pre amp stage or do you have to stick with Mesa own tubes.

You break the warranty by using other than Mesa tubes.

5751 has about 70% of the gain of a 12AX7. Not sure it would reduce harshness....but does reduce gain.

Some of the Mesa tubes are rebranded JJ tubes.
The fact that Stephen appears from nowhere, is sentenced to death in an emotional public trial without anyone interfering at all and is then altogether forgotten as if nothing happened, is already suspicious.
