Question.I bought a "ECC40 instead 6SN7 tube converter adapter" from Ebay a number of months ago. I am just getting around to using it and have a question. Does the glass "nipple" on the side of the tube line up with the black mark made on the 9 pin socket?
Thanks!
My own experience is that I have no way of knowing how a given tube will sound until it is in my own system and has a few hours on it. In many cases it is a difference in "flavor" and not really "better" or "worse".
I do use personal accounts to add tubes to my short list to try but I am...
Welcome.
Welcome. The short version is that this is a great DAC and tube rolling is mostly a matter of personal taste and system compatibility. You might want to use the factory tubes to break in the DAC and get used to it's stock sound. While doing that, read through the older posts before...
I would be interested in hearing more about your subjective appraisal of the VT-76. In reading about them it seems that their specs are not really an identical match for half of a 6SN7. I think that they have less gain and a greater plate resistance. I have a pair of them that have been...
I listened to the ECC40 Tungsrams yesterday. I let them run during the morning and checked in from time to time. They check a lot of boxes for build quality, thick glass and nice internal support rods.
My first impression is that they sound very good. Mine seems to be a bit weighted toward the...
I received my adapters from China for the ECC40 Tungsrams a few weeks ago and just received the tubes from the Ukraine today. I want to make sure that I am inserting the tube into the adapter correctly. Unlike 12A*7s, these tubes have evenly spaced pins so the insertion orientation is not...
The rolling starts to get a bit crazy. I have probably ~12 rectifiers., ~12 6SN7 + variants, and ~10 12AU7s and compatibles.
This calculates out to 12 x 12 x 10 = 1440 possible combinations!
I received my AZ1 from Poland yesterday. It is built like a tank. I always worry about shipping 90 year old tubes but this one is very solid. The box looked like it had been kicked through the goal by Messi but all is well! The adapter came from China as most do but is well made also.
Although...
