Title: UFO2 tube rolling Post by Tooppy on 04/03/23 at 15:01:32 As of now, tubes rolling hasn't really get into my room. I have the original tubes + the Decware coke bottle 5U4G I have the EL84 WC + ECC88 WC Wathen cryo Which of the - Rect - Power - Pre - that you all have tested and used has made the most significant changes, not slight changes, something blatant right away from the originals, with you comments on each tube "flavours". |

Title: Re: UFO2 tube rolling Post by ArtMan on 04/03/23 at 17:56:13 From my experience, the rectifier tube has a major contribution to the sound. Think of it as the foundation for the preamp and power tubes. With your amp and tubes, the Wathem 5AR4-WC rectifier tube would provide the superior synergy with your EL84 WC power tubes. That would be the choice I would recommend. The highs and especially the soundstage are excellent with this rectifier. |

Second that! Once you have the rectifier in place and have allowed enough time for the burn in you may consider trying the CryoTone 6SN7-WC in place of the ECC88-WC. In my CSP3-A I have the 5AR4-WC, ECC88-WC outputs and the 6SN7-WC input. Next I'm going to try the 6SN7-WC in the input of my UFO25 when I get it back, it has just been processed at Wathen Audiophile. A word of caution... an immediate discernible difference may not be to your liking at first. Give it 25 hours especially with the 6SN7-WC. Then try a couple of different adapters. The adapters can make a huge difference as I've discovered. I hope to have my UFO25 back in a couple of weeks then I'll be in a better position to comment further. |
