Recently 2 of my pre amp tubes on my RG50TC stopped working on me. I just wanted to know if anyone who owns this amp has ever went with different pre amp tubes and how did they sound compared to the stock?
Hmm interesting topic, I recently upgraded the power tubes on my Randall RG50tc to JJ's. I have never thought of replacing the preamp tubes, i dont know if you will notice a difference, but i am definately keen to here of the results, good luck!
RG's & Mesa's
I was recommended a combination of a jj, tung sol reissue, penta labs, and JAN phillips by Doug's tubes
