Tube el34

Contact Kevin at Upscale Audio, tell him what equipment you are using and your taste in reproduction(which varies widely, person to person) and he will hook you up. His matching, testing, and burning in procedures are second to none(as is his customer service). (http://www.upscaleaudio.com/bEL-346CA7-Typesb_c_86.html)

I always get a kick out of people who rant and rave about how good the Dyna ST-70 is. It is a nice sounding amp, but certainly no world beater. I owned one back in the day that I picked up from the original owner in beautiful condition. My next tube amp after that (this is going back some years)was an ARC D-76. The D-76 is so far superior to the ST-70 that it is like compairing a boy to a man. The poor ST-70 was a wimp in comparision to the D-76.

Let's see- You're comparing an amp that was introduced around 1960, and rated at 35WPC(actually more like 17WPC in reality) with one that came out in 1974, sporting 75WPC. Gee- I'm amazed that there was such a difference in their performance!! There have been numerous upgrades and mods offered for the ST-70. Many that truly improve it's output and presentation. It doesn't take much to bring one up to the level of performance of today's amps(of equiv. power). I enjoyed mine for quite a few years(performing my own mods), as the mid/high amp in a bi-amped system. BTW- The production of the ST-70 almost reached 300,000 units. A pretty popular amplifier it seems.

thank you for all this info. Maybe i will stick with EH el34. People says that they lacking bass control. But if they are musical it fine for me.

What do you thing of the paste for the connector? is it good? Do you know groove tube gt-el34?

thank you again

There was a blind shoot out of EL 34 tubes done by golden eared blindfolded audiophiles by Vacuum Tube Valley a short while ago of a total of 15 different EL 34 variants including Mullards, EH, etc and new and NOS Original TESLAS and the original NOS TESLAS were the hands down winner and blind favorite. Unfortunately they are hard to find and increasingly $$$.
