In Reply to: Evaluation of the change by replacing lytics with 100uF ASC caps for the B+.. . You're missing the boat! posted by John PA on September 21, 2004 at 19:48:51:
As a fellow Six Pac owner I wish I had your electrical know how. I would love to be able to tweak mine like you have tweaked yours.BTW, I have to disagree with you on the stock tubes. I get much better results from Svetlana EL34's. I have some EH's on order to see how they sound, but this last weekend I again went back and forth between stock and Svetlana's and it was really no match.

that they were poorly matched and as they aged they got worse, which I feel in this amp shortened their life. I spoke with Cary Audio and they get the tubes matched from China, and leave it at that. I bought another set of 12 from The Tube Store and they burn the tubes in and then match them. They have found that the "matched" tubes from China are no more matched than random tubes. The tube I got from The Tube Store sounded better, as they are truly matched, and have been running for quite some time. I can check current draw on tubes and the original ones were horrible with regards to being close to each other. The second set are still very close. This would take the strain off of each tube and allow for the best life of each one.ja in clear, sunny and a nice cool night, Tucson, AZ

I thought it would be no contest between the two so I ordered 12 nice new Svets. I let them burn in and listened and I just do not get the scope of sound I get with the EL34B's. Dennis actually tuned the opt's to the EL34B. I am not sure of why there would be a difference between what we hear but maybe it is the rest of the system. I have the true Svetlana and not the Sovtek version.ja in clear, warm and sunny, Tucson, AZ

Mine are the new ones which is most likely the difference. I'm getting the EH's next week. I'll post my thoughts after burn in.The six pacs are great right out of the box. But, at some point, I will send them back to Cary for any and all upgrades they can do. I sense their potential.

I spoke with Kirk the other day and asked if there had been any changes and stated that there were no changes to the amp at this time and they do not expect any because it is selling so well.ja in clear, cool and dark outside, Tucson, AZ
