Hope someone can direct me to a stereo receiver repair shop. (Would prefer somewhere in the Seomyeon area, but beggars can't be choosers.)
I have an old TEAC AG-D9260 AV Digital Home Theater Receiver, and I think the amp went out on it. Had a similar experience with an Onkyo Receiver when I lived state-side, and the cost was minimal compared to buying a new one.
