Well, I found my missing quad of TAD 6V6's that I've been missing for a few weeks now. I totally forgot that I put them in the glove box of my 4Runner when heading out of town to play a festival back on April 15th. They've been in there ever since. It's just starting to heat up in FLorida....I don't guess they've suffered any damage left inside a hot vehicle all day...no more than being lit up with 400 volts huh??? I'll try them out soon. Just thought I'de ask...silly me.
