what do I replace...?

[9am53]

hello boyshere is my latest question...I finally decided to try the baxandall circuit for tone. some old ampeg portaflexes use an almost identical circuit with some different r/c values, but I dont know which to change...should I replace resistors 10 and 11, and caps 5,6,8,9? thanks

here is the schem for my amp

those resistors and caps that I am inquiring are from my amp...

What are you trying to do? What do you replace => to do what?

Ah, I'm glad it's not just me I can't understand either....

sorry guys, as I often tend to do I assume everyone knows what I am talking about so I dont explain myself enough. I intend to switch out the resistors and caps from my amp and put in the ones from the ampeg. I am converting my PA into a guitar amp, so the tone stack as is doesnt work, but I am not sure exactly how many of the resistors and caps to replace...will C5 and/or C10/R13 have to be replaced, or do they not have a bearing on the tone controls...thanks guys

For whatever reason, I can't see the second image or click on it. Do others see it?

9am, you might want to report that second schematic.

hello, after what seems like an eternity of trying to make this thing fit 800x600 pixels here it is. R10 is 47K to ground. I guess what I am asking in a nutshell is whether I need only replace the r/c values within the tone stack, or if I need to change more ie, ones leading to and/or from the tone stack. thanks agian guys

one more thing guys...what is the reason for the 270K resistor in the ampeg schem on the bass control?
