Mark:
I had to chuckle.
I picked up a GR-64 off the curb Friday, hoping that there'd be some nice tubes inside. No such luck, but after cooking the caps in that Telefunken a few weeks back, this one will go on the variac for a few days before it gets a full test.
Now those two Telefunken 12AX7s in the Bogen Challenger that was next to it were a sweet find though
