I'm set up, so here's some pics for starters:
\'start3\' and \'radio.open\' both have labels added - might help some of ya overcome some doubts!
for the "missing tube" - one missing will leave an exposed socket, but sometimes "tubes" don't look like tubes - the OZ4's in the 3 radios I have are all different, one being only about 1.5" tall, and none are glass, 2 black something, one silvery metal - also check inside the cover, there was originally a label inside w/ a tube layout diagram
