[Hammarlund] HQ-170A VHF VR tube??

[Craig Roberts]

Pete, WA2CWA, said: "In your original post...you said this was a HQ-170A VHF receiver. If so, then R53, the 10 watt resistor going to the OB2, should be 2K, not 3K. ...if its just the 170A, then 3K is fine."

Hmmm.  It's all very confusing, really.  My receiver is indeed an HQ-170A VHF.  However, if I use a 2K dropping resistor at R53, I get 143 volts on the regulator tube socket -- which seems too much for the specified OB2 tube (but is correct for an OA2).  If, however, I use a 3K resistor as specified in the HQ-170A (non VHF)manual, the voltage drops to 104 volts -- which is just right for the OB2.  

Does anyone else have an HQ-170A VHF?  If so, what is the value of R53 and what regulator tube does your receiver use.

Many thanks, as always,
