I was able to get a Canadian made NOS Hammond 125D new in box for $25 CDN!

Per Ron's comments in forum post  https://philcoradio.com/phorum/showthrea...edback+tap I used the attached schematic for the 46-1209 feedback replacement.  I started by using a 4.7 ohm (R201) and 68 ohm (R202) as per the 46-1209 schematic and found a sharp squeal at low volume.  Then I used an 82 ohm for the R202 and it worked great.  For fun I moved the R202 up to 100 ohms but the sqeal came back.  Returned to the 82 ohm and I am quite happy.

Thanks everyone who chimed in on this and a special thank you for Ron.
