I have speakers a lot like yours and although my primary amp is the 45, I do use a Decware SE84UFO also... Dead quiet and sounds terrific!!!

Hey CJ, Check your messages..

Yes that and two guys I know have amps he built but, with mine there were problems that he even acknowledged and then said nothing was wrong with the amp.

Maybe but, I don't think he is wanting to sell his. I am also not interested in owning anything made by Oliver Sayes ever again after my recent history with him!!!

My friend Richard Gray is putting together a plan for one.

Well it's a long story but the short version is he built an amp for me that I had to send back because was bad in many ways, then after saying he would refund me he charged me a restocking fee!!! So he stole over $300 from me!!!

I would not contact Oliver Sayes for any reason what so ever, after the encounter I had with him recently!!!

PM sent...

Rich, These are what you want!!!

Hi Jim, With Your speakers you will need subs to use a real low powered amp and achieve good SQ, maybe look for a used low powered amp cheaper and go from there. If you want to really reach the pinicle of SQ with your speakers get a good DSP and go all active you will never look back!!!

I know this is a long shot but, I am looking for a single Blue Arcturus 71a tube. If anyone has one or knows where I can find one please reply. Thanks.. Jay

To the OP, while my room is smaller than your and I have Khorns in an all active system I have used a 45 type amp for over 10 years from 11 feet away and it would run me out of the room easily!!! I also have a Decware SE84UFO and I had to turn it down 7.5db to achieve the same levels as the Korneff 45 amp. Now I have a 71a SET amp that is 3/4 of a watt that's right about 750mw per channel and it will run me out of the room also!!!

Curious as to how they sound compared to other 6SN7 tubes?

Hi Jim, Ok I have a little time for this now. This whole thing started when I wanted to find variants for the 6SN7 tube, my pre amp and my Korneff 45 amp uses them. Anyway with really great sounding 6SN7 tubes being super pricey and hard to find I started my journey. Long story short I found some really great sounding variants, while in the process I was talking to my friend Mark that owns Rogue Audio and he said I should try the 12AU7 tube as sub for the 6SN7!!! Mark knowing quite a bit about tubes told me that the 12AU7 was the closest tube he knew of to the 6SN7, So now I have another option. Using an adapter I started with what I had a NOS pair of RCA clear tops, they sounded pretty good but the highs were recessed a bit kinda like in the background. Then a NOS pair of Valvo 12AU7's and they were better, thena friend told me about the 5963 tubes. I got some and they were terrific but noisy so I started looing for some quiet 5963 tubes. I got a pair of Sylvania gold labeled 5963's and they were dead quiet and sounded fantastic!!! I talked with another friend about a trade for a pair of Tele's 12AX7's for his 12AU7's, I know all about the Tele sound and I like it, I been using them in my phone stage for 10 years. Meanwhile while waiting for the trade to happen I learned about the Amperex 7316 square D getter tubes, that alot of people in the know consider them to be the best sounding 12AU7 tube ever made!!! So the hunt begins as luck would have it I bumped into someone that had both the square D and the Halo getter versions of this tube. I got one pair of each from him and was and still am blown away at how good these tubes sound!!! They are almost too good if you can believe that!!! In summary the 5963's are cheap NOS matched $50, the 7316's are high dollar tubes if you can even find them. I checked with both of my go to tube vendors and was told they are looking for them too!!!! The square D getter tubes sound the best with the Halo getter tubes so close it's hard to tell them apart. The only thing left to do is compare them to the mighty Tele's. I am told that the 7316's were Amperex's answer to the Tele 802S tubes.....

Well I don't really know nor do I really care about measuring anything that sounds really good!!! If it sounds terrific why measure???

My 77 Khorns have the original woofers in them and they sound just fine to me....

Rich, I already have a Korneff 45 and a new Decware SE84UFO!!! I will probably have trouble deciding on which one to listen to!!!

Contact me I just finished trying many different variants of the 12AU7 tube and found some awesome results with some cheap tubes and some pricey ones!!!

That's interesting he is building a 71A amp for me that will be ready by the end of this month!!! I am really looking forward to hearing this amp, it will be the last amp I ever buy!!!

Update: Both tubes test as new and close together, anyone have a pair of Tele 12AU7 's to trade????

I have a pair of tele 12ax7's to trade for a pair of tele 12au7's if anyone here has them??? I will test my pair and give results but, i already know they are good. These are my back up pair to another pair I have... Jay

Well first I have a friend that has a few of his amps and he said they sound wonderful but, his soldering skill are very poor. All of his amps had to be gone through and repaired. He also doesn't color code the wiring something that is undesirable. Then on another forum I read more of the same from others that bought his amps. With that knowing the shipping back to Japan is $300 I decided against. Even though I really want one of his amps I am gonna get it done here in the states. Hope this helps.

Thanks Randy, I was gonna have him do it but after some research I think not....

Hi Jim, No just been wanting to try one for a while now, I love the Decware amp....
