Human Factors; Procedure
After landing Runway 33; I exited on Taxiway K. Tower did not hand me off to Ground; so I called Tower for taxi instructions. After no reply from Tower; I switched to Ground and requested taxi instructions. After no reply from Ground; I switched back to Tower; and Tower instructed me to 'Taxi to the GA ramp via A; B.' I proceeded along Taxiway A and turned off my beacon/strobes (single switch) to avoid blinding effect. My nav/position lights and taxi lights (nose and wing tips) were all illuminated.I did not see Aircraft Y until starting my turn onto Taxiway B. From the angle; it appeared Aircraft Y had been taxiing in parallel to (or nearly parallel to) my direction of travel on Taxiway A. At no time did I hear taxi instructions issued to Aircraft Y.Because Tower provided my taxi instructions; I was not listening to Ground. When talking to the Tower controller after the event; I mentioned that he appeared to be working multiple frequencies. He verified that he was; and that both aircraft received taxi instructions on different frequencies (me on Tower; Aircraft Y on Ground).There was no damage to either aircraft. We both stopped short of contact between the two aircraft. Once Aircraft Y cleared Bravo to continue taxi to Runway 33 via A; I completed my turn onto Taxiway B and parked in the GA tie-down area. During this final stretch; Tower asked me to call him via landline; at which time I answered his questions for his safety report.
GA pilot reported a ground conflict while the Local Controller was working both Tower and Ground frequencies.
