Retubing the Bogner Shiva


New member
Hi everyone! This is my first post here. I've been a lurker for awhile, but finally joined. This forum has been the BEST. Lots of tasty amps out here I've been scrolling through.

I'm about to retube my Shiva for the first time, and have been considering trying the Tung Sol EL34-B's with Tung Sol 12ax7's, and a Sovtek 12ax7LPS in the PI. I was just curious if anybody knows if the Shiva will take kindly to the Tung Sol EL34-B's. I know Bogner says to use Wing C EL34's, but he also said some newer production power tubes might work as well.

Any tips or suggestions? Thanks again, and it's good to be here! :rock:

Sorry I can't answer your question but I just re-tubed my shiva for the first time also.
I went with
v1- penta 12ax7
v2,v3,v4,v5, reverb- Shuguang 12AX7 8th Standard Test
pi- Sovtek LPS Balanced Triodes
Ruby EL34BHT Matched Pair

From everything I've read and heard the Shiva does best with the chinese 12ax7's and LPS tubes.
I'm happy with how it sounds so far, no problems.
