Sorry I missed you last week. You will have a hard time finding either of  
those items. I understand that the noise blanker circuit probably has less  
value than its front panel switch  -  but that's just what I've read. As  
for a suitable replacement CW filter, any Ten-Tec 9.0 mhz filter with 200  
ohms in & out will work. The INRAD 400 hz filter is great in the radio  
($$!), but the INRAD 250 hz filter has way too much insertion loss and is  
not the filter for that rig.

One thing you might consider is an 8-pole 2.4 khz SSB filter to replace  
the 4-pole. It makes a heck of a difference, and if you have the audio  
active CW filter option, performance is acceptable with those two working  
together for CW. That could get you by until you found something to go  
into that pesky empty crystal filter slot.
