SB-401 Assistance

[Gary Harmon]

I have a SB-401 that has no heterodyne oscillation on 28.0 and was working
on 29.0 yesterday but not this morning.  I cleaned all the band switches and
replaced the 6AW8 with a new tube, the crystal checks good and have followed
the alignment instructions correctly.  All the other bands work normally.
Any suggestions where to look from the gallery???

Thanks and 73,
