G4/214 Geloso problems

wrote:

Frank,that is a nice looking receiver,,,It is double conversion..Two
6BE6 tubes in mixers. your problem could be one of the oscillators

indeed it was, during the resistor check & replacement I had made a bad
solder join to the first mixer's LO input... soldering back that connection
solved pretty much all of the problems.
The receiver is however quite deaf by today's standards even after a full
realignment.

not running...If you have a scope or counter ,probe pin 1 on both 6BE6
's should show a healthy osc signal on both..If no scope or counter,
you can use an auxillary receiver to tune to osc freqs,the manual
may show these freqs..On this old stuff it`s good idea to test all
tubes ,make sure that they are good..Good Luck 73 Harold W4PQW

Yes I have some test equipment, I just started to scope around for signals
and found the missing first LO signal. It seems to me that the xtal
oscillators for the second conversion have a bit low signal output. Maybe
bad tube?

Thanks a lot
