Hi folks. Is there a difference between the Hafler 110 and the Hafler DH-110 preamps? I traded a DH-110 today for cash plus a non-working 110, and they look about the same but one was clearly marked DH110 and the other was marked 110 and seemed earlier.
 
Pretty sure 110s are all the same. Do you have different markings on the case?
 
they are the same. the only difference "MIGHT" be whether they came as a kit or assembled.
usually a label on the bottom indicating the latter. both came with assembled PCB boards
with the kit requiring final wiring to switches, etc. there were cable assemblies to facilitate
the signal connections.

the PCB boards came in variations - BIG letter (A, B , …) in the middle of the PCB
with some changes in parts and certain cap locations. as a follow-on to the Dh101
it was totally metal films,
