You're welcome. Tube equipment is very forgiving. I'm guessing you don't have a variac. As an alternative, when you bring it back up, add a light socket in series with one of the ac lines going in. With a 100 watt bulb in series, the maximum the tuner will draw is less than an amp, low enough that you can observe, measure voltages if you have volt meter, before running it at full voltage. How intense the bulb glows will also tell you if you have a problem. If it looks like 100 watts, you have a short. It should be about 1/3 as bright as normal.
