Voltage Divider Resistors Blackface Fender- power tube resistors

I have a silverface fender pro reverb that I'm currently going through and replacing drifted components and a couple mods.

Regarding the voltage divider resistors found in the filter cap can. I cant find a schematic for the blackface pro reverb. Mine are different from the silverface reverb schematic (my amp's schematic) And I've read that they changed these values from blackface to silverface. All I can find about it says...

"Resistor changes in dc voltage dividor circuity. The 1kOhm resistor was replaced by a 4,7KOhm resistor. The 10kOhm was replaced by a 4,7KOhm."

So I assume the 2x220k resistoras in parallel with the larger 100uf caps are correct for both versions. but...

if you're looking at the filter can from the bottom side of the amp the 22uf cap farthest away from the 100uf cap side. so the first resistor from right to left if the amp is upside down and the front panel is facing you... (sorry complicated I know) This first resistor has a color code indicating 10k.

the next resistor going left is 2.2k

So I guess in a silverface these would both be 4.7k? but in the blackface one is supposed to be 10k and the other 1k. But I dont know which should be which?

Anyone have a blackface schematic for the pro reverb?
Will changing these affect the sound of performance of the amp much? I did get some 1 watt high quality PRP metal film resistors in a bunch of values so I should be able to easily replace them

On another note I've heard it's good to replace some of the power tube resistors to higher values... I think it said to replace the big 1 watt 470ohms on each power tube to 1k... is this a good idea? Will it affect tone?

Thanks a bunch! Sorry the post is so long, just gettin all the details for ya.
Anything is much appreciated!

I raise the wattage but still use 470k instead of CC's I use flame proof metal oxides 3 watters but 2's are fine as well. Mounted as high above the tube socket as possible. There is no different in tone between the two, Spend your money on your 100k Allen Bradley NOS plate resistors. And if you want to any others that have drifted way to far out, but only CC's in the signal path.

You have a wonderful amp hoss, My Pro Reverb is my baby.

Oh and cleaning up your heater wires and the rest of the lead dress is one of the most important steps toward better tone.

470k? They're 470ohm arent they?

and i'm going with PRP metal films for the plate resistors- apparently they have a great sound. american made, super high quality, like a modern version of the RN70's. I'm still gonna compare and record a bunch of component swaps and get my own ideas on this argument. Though I've already heard the benefits in pedals... so i'm pretty sure It'll be worth the trouble to say the least in amps.

Yes typo. I've done the same kind of tests, I ran myself crazy after I read up on Ken Fishers opinons. But in the end, unless its in the signal chain, I can't hear much difference at all. Read up on him, there are a few pdf's floating around from when he was writing for a magazine.
