I was reviewing some of my notes and noticed it has been just over a year since my original post describing my ST-120 start up issues well I'm happy to report I have had zero issues
since and I'm still using the JJ GZ34 rectifier tube installed at that time!
I do have another JJ GZ34, two spare Sovtek 5AR4 and two WZ68 Copper caps on hand just in case, If my system goes down Ill have to be institutionalized
I have 550 trouble free hours on my amp and am still very impressed with the incredible sound it produces, after a variety of tube's rolled I have been extremely satisfied with RCA black plate 12BH7 in the outboard positions and my favorite "Panasonic" labeled 12BH7 that Is my go to center tube.
I also changed out the KT88s out for some KT120 (385 hours on em) great combination IMHO for my system.
I added a Schiit Gungnir DAC about 485 hours ago and have been very impressed by it's ability to UN package and release the true accurate sound of instruments and voices it has truly upped the quality of the sound from my digital recordings.
I have also acquired a couple of Dynaco FM-3 tuners, a one piece circuit board and just about all the new components needed for a complete rebuild and will complete some time early 2015.
I just got the OK from the boss (Wife
) to buy a SP-14 pre amp! looking at options now and will be discussing with Roy soon cant wait!!!
After a year I'm so happy I decided to go with the Tubes4hifi kit amp it is truly an amazing bargain for a person like my self that wants to have an incredible sounding system but cant afford to spend two or three times what I did for the ST-120 and it sounds as good or better than the more expensive systems and best of all I assembled it with my own two hands and with the help and support of many on this forum, am I proud?
Heck yes I tell everyone every chance i get
Thank you all
