hi All  am just about done restoring a Kenwood TS-520, got new tubes in (6146B's) and noticed no ALC Drive reading  on 10 meters 28.5 when I am doing step 6.9  (transmitter neutralization)  of the operators manual.  Checked the driver tube in a tube tester and reads good.  The  other bands there is an ALC reading with the Drive so don't think its the driver tube.  Some say this is normal and check IP settings and RF to see if you are getting output power which I have not done yet for 28.5Mhz...this just doesn't seem normal.  If the RF board was bad think all bands would have this issue by simple logic?  All other bands there is an ALC reading when in TUN Mode with the drive selector place for maximum meter deflection...again tested driver tube and shows good...any theories that you all can think of?

 Not to worry Glenn all the old 520s did that!! I had one new out of the box and it did the same thing.. Still have it.
Just keep an eye on the plate current and go for it...
