Here's what fell into my lap: Heathkit WAP2 PreAmp Pilotone AA920 Amplifier Sherwood S3002 Tuner Eico HFT90 Amp/Tuner Sherwood S4400 Integrated Amp ElectroVoice EV1159 Tuner Bogen DB230 Integrated Amp.Anything I should do before plugging these in? They all appear to be in fine condition. I don't want to lose tubes accidentally. Most of my experience is solid state. And what's worth refurbing?

Wow! Great catch!I don't think you'll damage tubes, they're pretty rugged. If they're not spent already, I don't think you'll hurt them with a power-on surge or anything. The filament voltage is usually set by a transformer secondary. The components I find bad most often are capacitors. Many times the tubes are in great shape. A tube doesn't go bad in storage like a capacitor does. So check the capacitors, especially electrolytics.
