Electro-Harmonix 6CA7EH | Excellent tubes!
by Chris Robinson
These EH-6CA7s remind me of the older EI's that I would use on tour with my old Matchless in the 90's when they were easier to find. I use them instead of El34-s for a touch more boldness and headroom with my old Chieftain and it does the trick. Also using old GE 5751s in V1 and the PI positions.
Electro-Harmonix 6CA7EH | It’s like an EL34 and 6550 had a baby and that baby kicked all sorts of ass.
by Scott
Beefy, full tone. The EH-6CA7 brought my amp back to life.
Electro-Harmonix 6CA7EH | Classic Rock Tube
by Mike
Have a octet of these EH-6CA7 in my Primaluna Dialogue HP amp. Much more high and mid information with a tighter low end than the Electro-Harmonix EL34's. They took about 50 hours to really come around, but worth the wait. A bargain price with performance that shines, at least in my hi-fi amp. Been running them 10+ hours nearly daily for 8 months - no problems at all & sound great. A unique sounding tube, I listen to classic rock from cd-sacd's with PL Dialogue Premium tube pre-amp & Aurum Cantus M102SE's with ribbon tweeters and they just SING & POP! I've tried KT88's & 6550's and these IMO sound much more balanced & musically satisfying. I've been told these are mainly for guitar amps, but in my system they have found a home. Check 'em out in your hi-fi rig, I think you'll agree. by the way, the preferred series 5AR4 rectifier tubes are excellent in my pre-amp, best I've tried! Mike
Electro-Harmonix 6CA7EH | Mini Silver Jubilee? get these!
by Mike
These EH-6CA7 were recommended by others for use in a Marshall Mini Silver Jubilee. Excellent, just what I was looking for. Gives the amp more of a Big iron sound like the original Jubilee series.
Electro-Harmonix 6CA7EH | Excellent in Orange Rockerverb MKIII
by John
These EH-6CA7 have been fantastic tubes, and I absolutely love these in my Orange. I'll be sticking with these instead of the EL34's I was using before.
