Looking to sell this amp, link to original posting here, ( https://www.head-fi.org/threads/sold-massdrop-eddie-current-zdt-jr.954400/ ) items in same pictured quality, packaging, etc., comes with the extra stock tubes included as well a pair of RCA 6AK5 I purchased. I like this amp's sound, but in my current environment with wifi router right near me, the output transformer on this amp can introduce some hum (this is the 'fixed' version of ZDT jr. but the hum can be present with sensitive headphones). This sounds really awesome with my Focal Elex and even some planars without a hint of hum/noise, however I'm looking to get something that can be dead silent with the very sensitive Grado Hemp (sensitivity spec has to be off on their specs, it is by far the most sensitive headphone I own). I want to be transparent in case you may have the same issue.

Anyways, this amp has a great sound, and tube rolling has a notable effect, though stock tubes are quite good, just different from the RCAs. Please let me know if you're interested, would also be open to trade suggestions.
