Manley Neo 250s and Maggies

This response might be a bit late but I have owned the Manley 250's with Maggie 3.6's since May 05 and I love the breadth/depth of my soundsatge. I recently, based on Paul Fargo's recommendation, switched out the GT EL-34's for Electro Harmonix 6CA7's because the amps were going thru tubes. These are great amps and I wonder why I don't see more discussion about them on A'Gon.

Hey Xagwell,

What difference do you hear with the 6CA7s? SO far I have not had any tube issues with mine.

As usaul when spending at this level I believe the differences are minor, but first the 6Ca7's were perceived to be more reliable. They are biased at twice that of the GT's. The higher bias is at the recommendation of the tube dealer/not Manley. The tube dealer states the higher bias is needed to hear the bass improvement. I agree that there is an improvement in the base region. Second, their have been posts about these amps/tubes. This last time a resistor was blown so I sent them back to Manley at their advice for a mod/repair which was covered under the warranty. (I can't say enough positive things about their tech support) To date these amps/tubes are performing flawlessly. Also I subjectively believe my soundsatge is bigger as well. I hope this is helps.

Xagwell,

Which 6CA7 did you get?

Biased at 550ma?

I purchased 4 matched quad's/2 matched pair of the Electro Harmonix 6CA7's. The bias ranges from 0.52 to 0.55. I looked at other tubes like the "Winged C which I had heard about but the budget dictated otherwise.
