I make 3 contacts in 20 and 15 meters, work very good, but the next week
start and no work, similar problem with the old tubes.
Maybe there is a problem with one of the tube sockets. Sometimes the filament
contacts become weakened by heat and do not make good contact. So you only have
one tube filament working. If you can look to see if both tube filaments are
lit, you can tell if this is the problem.
