I just got a cheap 3400c in unknown condition with no AC adapter. Noticed some enterprising people selling the right adapters for $50 on amazon but .... curious if anyone has had success building a simple DIY version of these. The DC power port on the back of the 3400c fits a standard RCA cable snugly. Any reason I couldn’t just solder up a male RCA connector to any old 12v DC adapter capable of providing 2 amps?
