Hello everyone. I'm bringing an old guitar practice amp back to life and I believe I have found the bad egg after testing everything else with a couple of different multimeters. The only problem is...I have no idea what the heck this little guy is. I do know however that I can't get a continuity reading of any kind out of it. It's a black cylinder with 4 legs (two on each flat side). On one side each leg is marked with either a positive or negative. It is marked "Lt 99". The circuit board printing denotes it as "PH1". I looked into photo transistors but didn't find anything that looked remotely like it. I'm attaching a picture. Any ideas? Thanks!!!
