Wizard Modern Classic EL34 Tube Rolling

[Techdeth]

Which model of Mesa tube? I have a few to try.

Shit I’ve used all of them and been cool with them fr . I put mesas in my diezels too

First thing to note. My Sovtek LPS went haywire in the phase inverter. I just pulled it from the Ecstasy working perfect. Tube was lighting blue with the top and bottom looking like lightning flashing. Was audible aslo.

First test for EL34s is Sovtek EL34g. Pretty nice. As mentioned before these seem to have a little less compression. I like them.

Yeah LPS won't work in some phase inverters and it's best not to use them there in general as they can be finicky I hear.


Worked in my AC15 and it can handle but YMMV and I moved mine to V1 for good measure.

Yep, that's what I remember reading 10 yrs back when I had a 2010 MC1 100w. That amp came with the JJ Ls, but I also tried Siemens, Winged Cs, and the GT EL 34LS....the Groove Tube LS is basically a JJ L but the heat wings are big like a Siemens 34. Those actually sounded best to my ears. Not made anymore, but you can find them from time to time on eBay for cheap.
Pre tubes, the MC1 liked all Chinese to my ears.

The EL34-M/GT/Shuguang also has big heat wings and is available at Ruby Tubes.

I prefer the JJ e34l over the JJ el34s

I’ve tried a few other types including SED and EH and some Chinese. I think the differences are subtle. I just stick with the JJs as they’re cheap and that’s what Rick uses.

I do prefer Chinese high grade or 8th gen pres over the JJs. I use a sovtek LPS in the phase inverter.

The gold pin gold lions and RFTs sound good too, but more $

All that aside, you get more tonal variations with swapping speakers/cabs IMO

I'm really digging E34L's again..

The JJEL34II sceens are only rated for 450volts. Might want to check what the HR screen voltage is.

Aren't specs the identical on JJE34L, EL34, and EL34II?

They must have changed them. The El34L used to be 500 on the screens EL34 was 450 and the ii used to ba a lower output el34. They must have redesigned the II, the original version was not good when I tried them.

E34L, JJ Electronics Vacuum Tube
The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.


The JJ Electronic EL34 II is a different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. This tube has a thick and tight bass response. The mids are balanced and harmonically rich with pleasantly smooth highs. The JJ EL34 II is stronger than the original but not harsh sounding in any way. When overdriven, this tube has a warm and dynamic distortion that rivals many vintage tubes.
