In Reply to: RE: New preamps in the mail - EH 7025EH, JJ E88CC, and Pref Series 7025 posted by TubeAcolyte on March 16, 2021 at 14:16:02
Being a dealer, I'm surprised you don't know the difference between a tube and a preamp?Also, you have E83CC's not E88CC's...

Wow, what a cantankerous response to a minor wording detail I'm sure NO ONE cares about, and a very small dyslexic error of a single digit.
Woe to anyone who actually makes a real mistake in your presence, for they will suffer a wrath surely no one deserves.
Go be angry elsewhere.

Buy Chinese. Bury freedom.
I'm sure there are a few here who notice as there are some nasty people with a weird sense of humor. Nice tubes
Indeed! What preamp are you using them in, and how do they sound?
I love those JJs in my Mac pre. Never tried any 7025s...
It's my first time trying the JJ E83CC! I'm actually more into guitar amps and such, so these are going into V1/V2 stages to gauge color, tone, and reliability. I have a good feeling about them!
So far, the 7025EH is actually pretty good in my buddy's JCM2000. It was on a single JBL E120 8ohm load (which is SUPER sensitive and great ear-checking noisefloors). I see why it's a good one for high-gain applications. They're have a bit less gain, but not drastically so, which is nice in my opinion. Tonally, it's definitely an upgrade for the money spent over a lower-priced tube. I found cleans played warm and smooth, and it remained cohesive once the gain was cranked. Microphonics are essentially none-existent in my vigorous finger-tap-test. The real show stealing quality here is they're REALLY quiet - incredible noisefloor! Just... dead quiet!
I'd need to test the Preferred Series 7025 again, but I remember it being kind of like an upgraded Shuguang on steroids. They have a "forward" mid-to-upper-mid range character last I recall, which can be good and bad depending on the amp. I'm giving them another go to see how they do in a variety of amps to see where they fit best.
I'll be testing the JJs soon enough!

....why the JBL?
Well, I admit it wasn't exactly my first choice. Years ago, it was going to be installed it into a combo, but that idea fell through, so I had an E120 hanging around.
Now, I use it as part of my repair bench for listening for sound faults, blips, bops, and dooply-dos. It's loaded into a small 1x12 cab, which I bought empty locally. The back panel of the cab had two jacks; I wired one jack to the 8ohm E120, and the other to an 8ohm 200W dummy load resistor.
It sounds excessive, but it's very useful. I deal with a lot of vintage 100W RMS heads, which notoriously blow right passed their rating. So, it's a lot of power handling in a very small package that I can tuck away very easily.
The main drawback is that the E120, when pushed, is freaking insane. My brother loaded a 4x12 with E120s... And WOW... Loudest damned thing I've ever heard. That was the day I understood the effects of a decibel sensitivity rating...

That JJ frame-grid 12AX7 is a fantastic tube.
I use ten 12AX7s between all my gear and that E83CC is all I use. That's how much I like them!
A really excellent tube.

Well enjoy them! I'm afraid guitar amps are beyond my scope. But it's always good to hear about quiet 12ax7 type tubes.
