The unit is in fantastic shape, and sounds great with my DT-990s. I have one extra set of driver tubes (CV4010) with ~30 hours. I can't remember the name of the driver tubes I bought and have been using. It says 6x1n-EB on the side. If I can figure out what they are I will update this. They weren't expensive $30 or so if I remember correctly. The 6x1n and 6H30PI have several hundred hours on them, but they still sound great. There are little marks on the front of the volume knob, but other than that it's like new. I can take more pictures if you like, just let me know. $315 covers shipping and paypal. As far as trades go, I'm up for anything interesting, I would love a Bifrost or maybe a nice dac or dap +or- cash, maybe some headphones, just shoot me a PM.
Thanks for looking!
