[Amps] series directly heated cathode out to 4 tubes

[skipp isaham]

Hello, 

A friend in a foreign land has Emailed me 
to say his home brew four 572b amplifier 
filament transformer failed. 

He's been able to locate a same size 
~25.5 volt CT transformer and would like 
to use it. 

The Kenwood TL-922 has a series 
connection heater, the drive divided from 
the tuned input with coupling caps. 

I'd like to read any or your opinions about 
trying to drive 4 directly heated cathodes 
(572b) connected in series? 

Have any of you done said, does it work 
or not work for some reason? 


thanks for your replies.
