Ratings & Reviews
I popped this baby in and got some really cool tones. Soft and sweet tone but clear too, all at the same time. It has a nice three dimensional tone as well.
In my Tweaker 15 head as phase inverter, this amp probably needs a warmer tube but this tube is clear sounding and smooth.
Quiet, and more gain that you'd expect from a 5751.
More gain from the JAN-GE than from the JAN-Philips. These are really quiet and rugged. Make a nice V1 on a bratty Fender Hot Rod Deluxe. It stopped all the hissing and wierdness.
MARSHALL JVM 205H Phase Inverter
by D. Kidd
I had heard about the mixture of putting a Sovtek LPS in this position and thought I wouldn't notice that much of a difference... but, the JAN GE really smoothed out the gain channels on my amp. Brought back the crisp, gain attack that a Marshall is known for!!! Very happy and well worth the extra $$$.
Engl SE 670 EL34
by Not enough modern metal reviewers
After exhaustive forum research I resolved to purchase and try this tube in the PI slot after a recent lacklustre service (the tech replaced 2 worn stock engl/jj tubes with Electro-Harmonix, I don't think they are quite right for my amp)...made a noticeable difference but still wasn't quite right. I then subbed it into the gain driver slot and wowwww.....
The hedonistic saturation was reigned in to a much more articulate and focused yet raw growl without thinning the tone! The gain can be run much higher without sounding like a broken theremin recorded at a heavily clipped level and the hissy top end is completely smoothed. Absolutely love the lower mid punch shining through now on this amp and the right hand attacks on my 7 & 8 strings make me smile again. I am now searching thetubestore for replacements for the ehx tubes and a good quality long plate for the PI (and just a few to experiment with). I think after having done some research that this would be more conducive to the tone I am searching for. Great service, great turnaround from order processing to delivery (to Western Australia) and great packaging, thanks again! 4.5 stars because there is always room for improvement.
