[Boatanchors] De-chirping a Globe Chief Deluxe?

Charlie,
I have a Globe Chief Model 90A.  Not sure what the difference is between
your GC Deluxe and my 90A.  Mine does not chirp.  However, the keying sound
and characteristics do change from different crystal to crystal. With some
of the poorer crystals, it does approach a "chirp".

I kinda like the sound of a little chirp...in fact I'm attracted to them if
I hear one "CQing".  I would doubt very seriously that anyone at the FCC
gives a good hoot at the quality of ham radio signals anymore.  You might
receive a note from a friendly OO but I'd even be surprised at that.

Enjoy your GCD and don't worry about it.

73 and catch you for a 2x GC to GC QSO soon.

I'm trying to set up a couple of operating stations for SKN including a 
Globe Chief Deluxe / 75A3. Problem is, the Chief has a noticeable chirp. 
I'm using good FT-243 xtals. Checked the PS and the filter cap seems to 
still have its original value, and I'm using grid block keying as the 
manual recommends.

I realize it's a low-end xmtr but there is a certain charm in 
communicating with a flea market ugly duckling. Said charm does not 
however extend to getting a notice from the FCC due to a bad signal.

Before I give up on it, I thought I would seek advice from this group. 
Did these things chirp right out of the box? Any ideas (general or 
specific) for cleaning it up? I thought about tossing together an 
external oscillator with its own PS and running the Chief in VFO mode 
but that's kind of like cheating. Guess alternatively I could provide 
external power to the 6AG7 (and at the same time back down the plate and 
screen voltages quite a bit). Or replace the 5U4 with diodes and use the 
socket for an OD3?

Any thoughts?

73,

Charlie K1LDZ
