We are excited to release VTV Tube Buffer for the Purifi 1ET-7040SA high power module.
Music sounds smooth, open and natural through the combination of the 1ET-7040SA and VTV tube buffer. We have many discrete opamps to choose from when ordering.
Enhancements to the new tube buffer include:
—-improved DC offset stability
—-visual display of power and ready indicators
—-reduced noise floor
Hello
I have some questions. About how long is the life expectancy for the tubes? Is there easy access for tube change? Is there a stand-by option to increase tube life? How much for spare tubes? When will you put the monoblock version of the 7040 on the webpage (with tube buffer) How much will the monoblock version cost? I turn off my BHK pre at night to preserve tube life. I changed the tube with about 10,000 hours. I know this is a lot of questions.
Many thanks!!
Tubes should be good for at least 2500 hours, likely much more, 10,000 may be a stretch though. Replacement is fairly easy and you can use any 6922 tube. We can supply directions or you could return the amp to us for replacement. The standby option is through the 12V trigger. We are shipping the monoblock 7040 tube units not and We should have the monoblocks up soon.
