You have to bid on a few Mullards and have your upper limit in place or you will spend some serious money. I am sure I bid on 10 Mullards before I got one for $75.00 + shipping. The others went for OVER $100.00 each. I even tried to buy Blackmore's Mullard but he sold it separetely from his other ZD tubes (which I bought). Of course you can buy a six pack of Ultrons for $45.00 and roll a tube for each day of the week! It makes for a fun daily check list. Fresh...
There is a lot of good information on tube rolling with the Zana Deux on this thread. What is the experience with interconnect rolling? I have tried 5 IC's. Audioquest King Cobra, Audioquest Cheetah with 144 volt DBS, Audioquest Colorado with 144volt DBS (upgraded from 72 volts), My Audio Cables Paladium, and Morrow Audio SP-4 with silver Eichman RCA plugs. This is with the Sennheiser 650-Equinox cabled phones and a Marantz SACD player. I especially enjoy the imaging,...
Steve, Have you had a chance to check out the Tube forum at Audio Asylum.com. Also the SET amp forum at Audio Asylum.com. There is a lot of information there, and the SET forum participants are some of the true experts. Good listening. David Pritchard
Skylab, reminds us all correctly that Ultron and Hytron are Rebranders and not manufacturers. I think it is fun to have a six pack of "Ultrons" on the way from England. As I said- I was bored. Best listening. David Pritchard
Well I was bored and went to E-Bay. The six pack of Ultrons is now on the way! I did see that there is a pair of Fivre's for sale. He is the same seller that I bought mine from. He does make you pay a $6.00 Pay Pal fee- read his fine print carefully before buying. My ZD is #17. It had a faint high pitched noise- more on the right channel. Noticeable only with certain music- like piano solos. Not heard during non music playing passages. It would make certain piano notes...

The Isoclean made a major improvement in the sound of my Zana Deux. It is certainly directional in that the sound is improved in one direction and worsened when installed the other direction. The good news is it is easy to listen to the fuse installed both ways and decide. The change in sound is not small. I think it is worth a try. David Pritchard
Weccome to the exciting and fun world of tube rolling. Two variables that can be controlled are the quality of the tube pin contacts with the amp and the quality or the A/C power input to the amp. The first can be solved for the price of a tube (109.00) This is the Xtreme AV LLC Quick Silver Gold contact enhancer. This is a much better upgrade than cleaning the tube pins with alcohol or Caig contact cleaner. It does improve the electrical signal. Those Russian output tube...
I think the Valvo's are a great choice for the Zana Deux. It is especially pleasing to my ears with the Sennheiser 650 phones. Run your amp for 200 hours before buying any other driver tubes. If you get bored you can change your interconects, I am liking the My Audio Cable Co. Palladium cables a lot. $179.00-his ads are at Audiogon auction site. There is always the fuse upgrade, umbilical cord upgrade, contact enhancers, power cords, and different a/c wall...
I also have the Ps Audio equipment and it does work and is fairly price. Certainly if you buy the Premier power Regenerator($1499.00 with 1 year warranty direct from PS Audio rebuilt) you will have very good newly created A/C. I great value buy is a PS Duet conditioner for $199.00. It filters the A/C power at your A/C duplex socket. Add 1-3 PS noise harvesters and this is a nice passive system. Replace your crumie standard wall socket with a PS audio wall socket for...
