Dared VP-845 Bias Adjustment? 845W Tubes?

Brian..No mods. None planned. Love the sound just as it is. I run a Melos Phono pre amp into one of the line inputs. If I ever got a sub..I'd run it off the speaker level, so not concerned about a line sub out on mine.

I saw your other thread regarding 6SN7 input tubes. Ive rolled Tung Sol Tall Bottle GTB Black base...To polite for me....RCA 5692 Red Base were very airy and smooth as silk, but bass was way too light....Ken Rad Black Glass had killer bass and mids and wasn't bad on top..I could live with this tube, but I found that the stock Chinese 6N8 is by and away the best so far. It has drive and dynamics and very good bass. Halographic more so than any other Ive tried..so I keep coming back to these. I figure they knew what they were doing when they used this tube. That said, I have a pair of 60's Raytheon Short bottle clear glass on the way to try.

My biggest change came from the 845M's and a pair of 50's Tung Sol 12AX7 that came from a Fender Tweed amp. Really textured and musical. This is my current and best sound so far.

Best,
Ken

You suprise me by saying the china 6N8 is one of the best you have heard considering all the rave reviews the Ken Rad's and Tung Sol's get. Would you be willing to sell your Ken Rad's or Tung Sol's? Email me at: Brownmakkles@yahoo.com if you would sell them. I'd offer you a fair price or just let me know what you would want. Also, I read that there is no such thing as a Telefunken 6SN7 so what are people selling on ebay??? Two places stated that Tele never made a 6SN7 tube EVER. Makes me wonder. It looks like you have tried about all the tubes I want to try. If you are not interested in selling them to me, maybe rent/loan them to me? I could pay you and use them for a day or two just to see how they each pair sounds. That way I can base my decision better. I'd take really good care I promise! White gloves and all! :) I know it's a long shot but let me know. Thanks.

Brian,
Both the KR and TS are already sold..But im curious regarding the Raytheons when they arrive I'll let you know what I think of them..I also tried RCA Gray Glass VT-231 and some Short bottle Sylvanias some time ago..sold them too. Just wasnt right in this amp. I sure would like to try the famous TS round plates, but I wont pay that kind of money just to try them. Dont know, but seems the stock 6N8 are good enough leaving alone as long as you change the other tubes. as I did..this works for me. YMMV of course. What PC are you using on the back of the amp?

[GT: ??? GTA: top getter, white labels on glass, black base, round mica with diamond points scattered around it]
GT: This tube certainly lives up to its ‘legendary’ status. Why? Because it never existed. 6SN7s were NEVER made by Telefunken.
This tube is always sourced from Philips Holland (which in turn sourced from 1960s East German or Russian factories) Also occasionally rebranded as Ultron and Hoges.
GTA: This tube, while labelled ‘Made in West Germany’, was almost certainly not made in West Germany. Most who purchase this tube have been disappointed with its sound, describing it as ‘boring’ and ‘dry’ (AA).

This above is from Head-fi site..Yes, tele did not make a 6SN7.

I'm using a Miova (canadian) power cord. It cost me $50 plus shipping and is quite impressive. I have other more expensive power cords that don't compare. The locking interconnects are also very nice and sound great. Thanks for letting me know the status on your 6SN7's. I'm looking at a matched pair of KR and TS on ebay right now. The TS's are NOS and the KR look nice and are possibly NOS. I'll test them when I get them to be sure they are in good working order. Check out this ebay auction (Item number: 230112569253).

Also, whats YMMV???

Thanks,
Brian
