[Crist Rigotti]

Be careful about attempting alignment on one of these old TV sets. Its a lot more difficult than aligning a radio. The video IF must be aligned with a sweep generator, oscilloscope and accurately calibrated marker frequency generator.

Do you have any reception problems that an alignment would correct? If you have good sound and a clear detailed picture now, its probably better left alone as it will be hard to improve by alignment and its very easy to mess up and make it worse. 

I'm going to align the audio first.  Just as a learning experience.  I'm leaving the tuner alone!
