Hello everyone!
Amp - LittleDot Mark IV (Non-SE)
Cans - HD-555/HD650
Other than sending this back to LittleDot, I was wondering if anybody might have experienced this issue as I'm sure it isn't isolated to just the LD Mk IV.
Description:
I purchased this amp from head-fi years ago. I haven't been able to use it for about 2 years. Anywho, right before I stopped using it, one of the channels had died. About a week ago I attempted to use the amp again and swapped the fuse as per instructions found online. Now I have 2 channels, however this is what I'm running into now - As a pre-amp/pass-through, the volume is perfect! It sounds nice and at times is a bit too loud for my taste.
However when I use it as an amp, I noticed that even when it isn't plugged in, I can still hear very faint audio (coming from my source) which is able to be increased slightly by turning the knob to max.
Things I have tried:
Changing fuse
Used all combinations offered by the Gain switches
Swapped multiple power and driver tubes (sorry if the names are wrong, but the big tubes and small tubes)
Tried multiple sources - Phone, computer, XBOX 360
Tried multiple power cables
Tried multiple RCA cables
Tried multiple cans
Cleaned the bottom of the tubes and as a last resort, lightly sprayed compressed air into the amp from a good distance away as to not damage anything on the PCB
Outside of those things, I'm not aware of what else I can do/not sure what I'm capable of doing.
Would you suggest I send it in or are there any solutions that you folks know of?
Thank you in advance! I will do my best to monitor this thread.
