[Boatanchors] 6146B

[Jim Wilhite]

I missed that, but since that is the only difference, I can see why it might 
be a problem at VHF and maybe even 10 meters.

I did some repairs in the 1970's and 80's and saw troubles with VHF land 
mobile equipment (30-300 Mc) as Glenn has spoken about.  But I can't see 
trouble with the tube below about 20 Mc.

It will require a bit of neutralization but other than that it should be 
fine.
