[Heathkit] More DX-35 problems

[Mike Goshay]

756v X .120ma=90.72 w INPUT. You must have a neutrilization problem as your 
final  is now actitng like an oscillator. Have someone double check your 
rebuild for you. Musta miswired something somewhere.  Mike G w6we

Subject: [Heathkit] More DX-35 problems


After correcting some stupid mistakes (One bad solder joint and a unsoldered
connection) and the assistance of a few list members, I was able to get B+
to the oscillator.

The rig works except I have a very shallow plate current dip (at 120 mA (756
volts)) and I can not adjust the grid drive. It stays at 4 mA and can not be
changed with the drive control.

Also, the antenna loading control has NO effect on the plate current
reading.

The watt meter shows 100 watts into a dummy load.

The above conditions exist on any band, using several different xtals.

The rig was rebuilt with all new resistors and caps. . . .

Any ideas on correcting the above problem(s)?

TIA es 73
