Working on a A72T3  and I have a question about a Condenser.    The condenser Part # 505454 states the following - (.05 Mfd. 400 volt (low impedance at 455kc -- do not substitute ordinary condenser)

I look on Just Radios and I didn't see any condensers listed as low impedance.  What type of condenser should I use to replace the existing one???

Thanks
