Ratings & Reviews
Great Fender Phase Inverter tube
by Dennis Mecham
This tube give a sound with greater dimension more that any other tube I've tried in the V6 position.
A great, clean sounding tube. I put one of these in the PI position of my orange or15 head and it sounds fantastic!
I had JJs in the pre amp section and replaced with these guys. Wow what a difference! Total softening of tone. These run with two 12au7 which were also replaced with the JAN-Philips 5814 what a team together. More and better sound than the JJs. NICE!!!!!!!!!!!!
FENDER 65 SUPER REVERB RI v3 v6 PI
I brought 2 of these at first for my reissue fender SR, and had the triodes matched. I read that having them match in the phase inverter makes a big difference. THEY WEREN'T LYING. The reverb sounds so much better and the amp feels more powerful, like I'm not fighting to find a good tone. Its working for me. I also put the preferred series 7025/12ax7s in v1 v2 v4 v5 and tung sol 7581As for my power tubes. To cap it off i put a Mullard GZ34/5AR4 in and it sounds incredible. Sounds just like my 64 super reverb with more clean headroom. For this price you cant beat it. I bought them in bulk and put em in all my combo amps. Thanks again to tubestore.com you guys are the best !!!
QUIET ! in my 68 Custom Deluxe Reverb
by Paul Torres
The 68 Custom Deluxe reverb has many virtues BUT the negative feedback resistor is 1.5 - making it more touch sensitive but also noisy. The Reverb for the Custom also sends a lot of white noise. I use these in V3 and V6 and WOW the reverb sounds better and is quieter.. Use a 12at7 to Cleanup V1 in that Custom as well.
