Review JJ E83CC 12AX7 Low Noise & Microphonics

By: on 28 October 2023
I'm using this valve in Audio Note stereo phono pre-amp kit. A two-stage design using 12AX7 in V1 followed by 6922 in V2, gain is around 40db typical of moving magnet phono stages. I have read great reviews of this particular valve on the Audio Asylum forum and whole heartily agree this valve is as good as any treasured NOS 12AX7 in which I have a few off which are currently sitting on the shelf. The highs are sparkling, the mid-range is to die for and the bottom end when required is sub terrarium. This valve is a modern-day bargain and I hope JJ can continue manufacturing as the Russian equivalents sound very pedestrian by comparison. And EVATCO did a great job in packaging combined with great service from Australia Post.

New JJ twin triode

I've tried to like them but have never been a fan of the standard JJ 12 AX7 as they dull most amps I have tried them in. I am glad to report these are, to me, a vast improvement in tone quality. I replaced two 48 year old RCA 7025's that my old Twin Reverb came with and was shocked at the sparkle the amp now has. Admittedly, the old valves were well used and I don't think I've noticed the gradual decline in tone over the years that much, but these E83CC's really livened things up. They seem to have plenty of gain. The amp has a bit more growl to it now. I'll certainly get some more of them to try in other amps as they seem like a winner to me.

The BEST new production 12ax7....

So excited, I own two JCM2000 TSL100 heads, and one DSL20HR. I have received the brand new JJ e83cc frame grid valves to try in V1 of all my heads, so excited to try these too, as I have seen great reviews and the EQ curve of the valves have a mid boost... HOLY HELL!!! Not are the only super quiet, BUT, the boosted mids is soooo DETAILED, RICH and un-fizzy, and NOT harsh!!! Perfect for a Marshall TSL100 and Marshall DSL20HR for Thrash Metal. NO BOOST PEDAL REQUIRED ANYMORE!
