[Amps] Plate choke question

[Charlie Ocker]

Greetings,

I'm building my first homebrew amp.  Making slow but steady progress.  It is a
pair of 3-500z in grounded grid.

I have acquired an old National R-175A plate choke.  It is in good shape, and I
have measured it's inductance at around 135 uH.

I also have the main choke from an SB-220.

Question:  Can I use both of these in series for my plate choke?  The amp will
not have, nor will it be used on, the "WARC" bands.  Standard 160 to 10.

Just looking for ideas.

Thanks es 73,
