Frankiealverti. Houston...We have a problem!!!! Are you certain the tubes are 7029's. I have never heard of a 7029 designation. Perhaps you are confusing it with the 7027 or the 7027a. If it is a 7027.... Yup, the 7027 is electrically similiar to a 6L6 and should be fine in the supratek. That said: Am I missing something here? No offence but I would be "highly suspect" and immediately ask myself why anyone one would go through the exercise of relabelling tubes,and for what reason other than financial gain. Flat out Fraudulant if you ask me! The original old stock 7027 is a rare breed indeed and I have only come across this tube once or twice in over 30 years. A local musician brought in an old Ampeg guitar amp that employed the 7027 tube. I could not find replacements for them and had to retrofit his amp to operate with the 6L6's. Rumour has it, that the 7027 is the King of Tone and the cats meow in the this old Ampeg. The gentleman I am referring to is an incrediblly talented blues player and quite a famous recording artist. His comments were....What the f_ck did you do to my amp man! Well sir... " I put some [old stock] 6L6g's in it man as I couldn't find the 7027's anywhere" I could only imagine that the guitar amp crowd would probably trade in their back up guitar for a pair of these! Frank...I don't doubt the original old 7027 sounded better in the Heathkit W5's but I would be willing to wager that they are probably new stock chinese or russian metal base 6L6's with the labels washed off. Why take the chance in your Supratek anyway? Regarding the preamp making noises when your using the phono stage. Have you tested the rectifier? I would hazard to guess that your Mullard GZ-37 is either very weak or has grossly imbalanced halfs.This artifact you describe is really not that uncommon particularly in the supratek with phono stages. Yes, I believe the GZ34/5ar4 would be the safer choice. By the way: WOWZA and well done man!... You have one fabulous rig there sir and a very fine ear. To this very day I am still kicking myself for selling off my Radford ST-25. Over the years....I have had my share of highly regarded amplifiers paired with the Quad 57's and I can honestly say I have never heard a better amplifier than the STA-25/quad combo. Outfitted with the Genelex kt77 is pure magic with a capitol M. Now add the mighty supratek into the mix....sigh. Can only imagine!!!!
Preamp Deal of the Century
If anyone is looking for a true "World Class" preamp at a very fair price..heed my advice. I just recieved a Supratek Syrah preamp that was hand built by Mick Maloney in Western Australia, and it is absolutely beautiful! This preamp is the best deal you will ever find. I would put it up against any preamp out there for both looks and sound. Price? $2500 for the Syrah (includes Killer Phono stage). Not into phono? Try the Chardonney line stage for $2100. Don't get me wrong, I am not associated with this company. I am just a very happy owner! This preamp is VERY dynamic, yet liquid. It conveys the sound of music better than any other preamp that I have ever heard! You can check out the Supratek website at www. cantech.net.au
