Yes. Be careful not to wildly disturb the physical placement of the other components. Good luck!

Is this rascal inside the VFO can...? When I had this shield removed a week ago to clean the guide shafts & add a ground strap (to address my frequency warble issue), I guess I was so distracted about safely removing the doggone thing that I failed to notice any transistors or diodes hidden therein...in fact, I recall seeing only a couple of discreet components on the small circuit board, i.e. fixed capacitors... The schematic in the T4-X manual shows the diode to be ensconced within a "T1", along with the VFO & buffer transistors---yet the physical VFO can is marked "T5"...I can see no "T1" identified in any of the photographic views, and most of the components in the underview photo of the rig in the manual do NOT identify a whole heckuva lot of the parts (I guess I got spoiled by years of looking at Heathkit manuals!). Any clues as to the location of D6 before I start dis-assembling things...? Many thanks in advance, & my vy ~73~ de Eddy VE3CUI - VE3XZ _____
