It will NOT hurt anything--epecially since an early-80's set is nearly sure to be HOT, but if the set worked ok when it was put away...and if it was stored in a climate-controlled environment...it might not need it.
I just grabbed a 1989 Sears-Sanyo set, that has NOT seen much use. (ONLY....because I worked on then when they were brand new, so I have a "soft spot" for them). jThis one is a COLD set, with an SMPS supply, and full A/V I/O . It worked PERFECT (BW snow, anyway), NO vertical problems I can see, tube seems perfect. I did not bring it up soft, I just "let it fly", where it was when I decided to take it. SO--if you have a variac--go for it. Start at 75V, and see if the current is ok, AFTER it does degaussing. A set like that should not draw more than maybe 1.5 A, Maybe less, once everything is up. IF you see something like 2.5 to 3 a at 75 volts and it does NOT seem top drop if you got up just a tad....you DO have a problem. Last edited by rca2000; 11-05-2015 at 11:34 PM. Reason: Add info.

Awesome, many thanks for all the info. I'll run with your suggestions and let you know how it goes. It's an '81 GE, allegedly working when stashed away, but no idea how it was stored... so better safe than sorry.

Never hurt a SS set with a variac. There are a few Sonys I
would never risk it on though. First unplug the degausing coil so it dont give bad current measures. If non-remote start at 75 V watch the current. Be sure it dont go above abt 2 A. As it warms up it will drop a little. As you slowly turn it up the current will go down & on almost any SS set be about .75 A at normal line & picture. If a remote you have to keep trying the on/off til the relay closes. Watch the current as you do it. Sometimes you gotta go fairly high to get it on. Newer sets may need other tricks to do it. 73 Zeno
