Two Questions & a WTB List

[Alan W. Fremmer]

Fellow Collectors/Restorers,
 
1. Recently acquired a Viking Challenger in very good condition but missing  
ALL the screws that attach the front panel and chassis to the cabinet.  Can  
someone tell me the size, color and metal type of those screws and whether or  
not they are hardware store items?
 
2.  Would like to get a spare set of tubes for the rig.  It uses  3 - 6DQ6A 
tubes which don't seem to be as readily available as the B  variety.  Are the 
tubes interchangeable or must I look harder for the A  type?
 
I would like to buy a KNOB for the function switch for the  aforementioned 
transmitter.  All other knobs are original.
 
I also need a FUNCTION SWITCH for a Knight T-150A.  It would  be nice to find 
a BUFFER TUNE CAPACITOR as well as a TUBE SHIELD for the 7189,  although I'm 
not desperate for those items.
 
Finally got my Eldico TR-75TV2 working.  Would like to buy the  original 
ceramic coil forms that came with the rig.  They are fluted in the  long dimension 
as well as being grooved around the circumference.  They are  2 inches in 
diameter.  Would also like to find the grid coil form  assembly.
 
Most of what I'm looking for is probably unobtanium, nevertheless hope  
springs eternal.  At the very least, I should have my questions  answered.
 
Thanks, in advance, for any help you might give.
 
73, Alan - KB2HEI
