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...
Headphones not for sale
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...
AudiogoN has a new listing tonight for a pair of Brimar's 6SL7GT for $150.00. Not a bad price. They are not mine. Good listening. David Pritchard
Yes, The Iso Clean fuse is still allowing the Zana Deux to reach towards it's full potential. If buying a new fuse you can use a 3.3 amp or a 4.0 slow fuse. I just tried two other "system enhancers" that have the ZD singing. First was to replace the a/c duplex receptacle with a PS Audio ultra receptacle($99.00). Other good choices are Hubbard, Jenna Labs, Porter(about $40.00). This is an easy self install-just be shure to pop the correct circuit breaker and clean the...
I thought I has my information correct. In 1911 M.B.L.E. began making incandescent lights with the Mazda brand. In 1924 they began making vacuum tubes with the Adzam brand. Phillips bought the company in 1957. According to Sibley some Adzam tubes were made by RCA for export. It is a good sounding tube. Good listening. Drahctirp Divad
Following tube linage is fun and frustrating. Adzam is indeed Mazda backwards. But , who owned Mazda? Phillips. So is the tube French(Mazda), Belgium(Adzam), or Dutch(Phillips)? It is a good sounding tube that is not often for sale in the U.S. I think I will take out the Fivre and put the Adzam in the driver seat for the weekend listening. Good listening. David Pritchard
