Tube swap 4601 -> G07?

swap

The 4900, 4600 and go7 tubes are the same but the yokes are not. Although I do believe the 4600 and the go7 yokes are the same as well. Ohm the yoke to make sure.

NO NO NO. The 4600 yoke is low impedance. The G07 is high impedance.

Remember the G07's yoke wiring is different than other manufacturers.
 
Thanks,

Thanks Ken. So the 4900 and the go7 are not the same. Is 4600 and 4900 the same yoke? I have not checked in a while because when i do a tube swap I keep the yoke with the chassis. At least I told him to OHM the yoke first. Partial credit?
 
IIRC, the 4900 and G07 are both high impedance yokes.


Yes, but different wiring and different connectors.

In fact there are two different yokes in the 4900 series monitors which if not connected to the correct 4900 chassis will cause a foldover that cannot be corrected.
