RCA 6K3 Preliminary Capacitor/Resistor Research
#12

Not to reply to myself, but, I did find this guide from back in the day already as an attachment in this forum, though I don't know the context of the post:

https://philcoradio.com/phorum/attachment.php?aid=5868

This appears to be the identical candohm (from an RCA 6K2), or if not, the values it is supposed to have are the same.  I know it has said to use 10 W resistors, but some of these values are really pushing the bounds of the 20% rule of thumb.  I've been going with JustRadios.com, so if people would recommend a different source, I'm open to trying something else.  I'm seeing a few other closer values in 5W.  Both the 5W and 10W are advertised as +/- 5%.  Would the following values be acceptable in this case (replacement value is closest 10W, with closer 5W values indicated in parentheses if available):

Orig -> Replacement
3.5K -> 4K (3.5K available in 5W)
13K -> 10K
85 -> 82
175 -> 200
40 -> 47 (40 available in 5W)

As far as how to install, I was thinking of getting a 13-terminal strip to be able to space things out, since heat is a concern and also I understand that 10W resistors are going to take up more space in the first place.  Something like this from Tube Depot: https://www.tubedepot.com/products/termi...-terminals
Maybe not going the same exact route as in the guide but a similar premise.  I like the dual terminals to keep the resistors and connecting wires separate.
