Hey guys, a request for a little advice. I want to try these Tung Sol 5687's d-getters I hear so much about. First, when I google Tung Sol and 5687 it took me to Tube Depot:
Now, they say the tubes are marked United, but they are definitely tung sol. Can I trust this? I have heard Tube Depot mentioned around here, so I am assuming they are a reputable dealer that knows their tubes.
Second, there are several "testing" options in the drop down menu there. Standard Test, High Gain, Matching, Balanced Triodes, Matched + Balanced Triodes, Low Noise + Microphonics. Any of those I should go for? And perhaps a brief explanation of each?
Thanks for the help.
I belive Mikhail now has a lifetime supply of 5687tubes in stock too.
