Narrative:

Aircraft X; arriving with inoperative PA; had history and all right&es were busy. Although I am not experienced I took it upon myself to repair the problem in order to get aircraft out safe and on time. When aircraft arrived at gate; I cycled the PA amp circuit breaker with no help. Due to my inexperience; the repair process was slower than if an experienced right&east did the repair. I asked my lead to order a PA amplifier to replace but was out of stock. We decided to rob one from aircraft Y which was at the hangar. My lead called the hangar and got permission to rob the part. I went to the hangar and removed the part from the aircraft. I assumed my lead made a write-up for the robbed part; but I never followed up. I take full responsibility for this non action. My lead was very busy and I was trying to turn the aircraft for dispatch. I installed the part on aircraft X and was successful in the repair. I completed the paperwork for aircraft X for dispatch. I was in a hurry and had problems obtaining the company part numbers due to only half of a company part number label missing and the small print on the other labels.
