[HBR] Need advise: protection for my only 1600 kcs xfmr

[C Eus]

All:
I reviewed just about all the HBR circuits.  One of my concerns is that B+
to the mixer tubes and IF amps runs directly through my precious set of IF
transformers. I wouldn't want some unfortunate short to take out any of
these transformers.

Currently (pardon the pun) the 1600 Kcs IF amp is fed through the IF
transformer through the primary winding and then through an 1800 ohm
resistor, which is filtered by a .02 uF cap.  Ditto with the 100 kcs
stages.

Is it possible to feed signal output from the plate of the mixer/IF amp
tubes to the next stage using a plate blocking capacitor and then feeding,
directly, the plates of the mixer/amp tubes using the 1800 ohm resistor and
placing the .02 uF bypass cap on the bottom end of the resistor nearer to
the B+ source?

If this is a "yes,"  what would be the value for such a cap?  As to the 100
kcs side of the house, I suspect the value for such a plate blocking
capacitor will be much lower.

I don't have the background to determine these values (other than good old
X=1/(2*pi*F*C) and then try to chose the value showing the lowest impedence
so the tube "sees" the impedence of the transformers instead.

Any advice will be most helpful. Thanks. Cal, n6KYR/4.
