HELLO ALL,  have had my zen and csp 2 for over a year now and the only tube rolling i have done is the rectifiers.  bendix 6106 are my favorites.  have been wondering about el84 outputs.  bought amperex and was very disappointed.  maybe buried under a quilt would describe the result.  hooked those tubes up with my dynaco st 35.  all good.  within limits of that amp.  have lots of russian 6p15p ev.  they sound as well as you know they do.  question:  what quality tubes sound well?  is there a known problem with amperex tubes re our little zens?  better choices?  hope someone out there  has had an experience in this matter that guides me to better out put tubes for my little zen which i would die for.  don

hi again,  i guess your last post would mean you have not had good results trying different output tubes.  the reason i wanted to try better nos tubes was because in place of the 6p15p ev we now use i had tried some old sovtek el84s and liked the result.  reasoning that high quality el84s should sound even better i bought the amperex and was very disappointed.  so, again, i ask has anyone had decent results with trying other nos output tubes in our little zens?  i have obtained a lifetime supply of the military  6p15p but i am always up for a new direction if someone suggests it.  thank you,  don pettit,  long beach, wa

The Zen was designed for the 6P15P-EV (EL83; SV83) tube. Therefore, using an EL84 in there is counter intuitive.

The TABOO was designed for the EL84 and using the SV83 is less than optimal. I liked the TABOO with the 6P15P-EV with the CEE mod but liked it more with the 6P14P-EV, which is a souped up EL84

it's me again.  i did have the cce mod done about 9 months ago.  slight improvement.  not nearly as much as when i started using the 6106 rectifiers.  all good, don

hi again ranch,  my intent is to try all options.  i started with 6dj8 for no particular reason.  will be trying 6922 in due time.  have gotten chinese 274b.  and 5v4.  and 6 6106.  and 6 gz32.  the gz34 i have seen are priced way high for my skinny little budget at present.  but time will improve all things, right?  have cryo'd my wall socket fitting,  power cords and my russian input tubes.  looking to do more in the future.  if enough improvement takes place i may be able to purchase a taboo in the future if the republicans do not cut my social security too much.  lots of luck, right?  don pettit

thank you,  RUSH!!

exotic tube rush, RUSH!!!

hi terry,  it is refreshing to hear that el 84s work will in my little zen,  particularly in light of steve's mentioning that they work well in in that amp.  but that little guy is now in a small room in the rear of the house into which i retreat somewhat rarely as it is not a really good venue.  i obtained second hand an se 34.1 which has barged into the front room and taken over.  came with el34 ruby tubes; very nice.  but spoke with ron at cryoset and ordered tung son el34s, cryo'd of course as i believe in the tecnique absolutely  probably will arrive tomorrow.  hopefully will have them "burned in" by monday.  but terry, must inform you i have not the skills to do the adaptation you have done.  admire your skills!  thanks,  don pettit, long beach, wa.
