I just picked up a 37-630 and was looking through the chassis to see what caps/resistors I needed to order and noticed a couple of things that I hope the experienced members can clarify for me.

The first photo shows a .25 cap and what looks to me like a mica cap attached on top. I assumed from the base view of the parts list that these are, #34, a 400 ohm resistor and #35, a .05 cap. Both of these items look original so I’m confused as to how to proceed with replacing these two parts.
The next photo shows what I believe is #61, bias resistor, but the base view of the parts list show a wire wound resistor for #61. I’m new to this hobby so again I’m confused. I checked it and it read 230 - 10 - 38 ohms which compares well with the schematic. Again this part looks original so am I to assume that it wasn’t originally made with a wire wound resistor?
Lastly, #25 and #27 refer to “semi fixed” condensers. I haven’t come across this term before and I haven’t disassembled the radio far enough to locate these parts. Can someone enlighten me as to what is meant by semi fixed?
My chassis is a Code 121.
Thanks for your patience. I’m new to this hobby, just started on this radio and I know I’ll be back seeking advice again soon.?
