[Drake] Drake Digest, Vol 127, Issue 1

[D C _Mac_ Macdonald]

I have manuals for TR-4C and TR-4CW. Neither has a parts list. 
 
The item in question is the receiver AF Gain (R91), receiver RF Gain (R113), and Power On/Off switch S5, all on a concentric array. Apparently even Gary Barrell doesn't have them available!
