Got my kit, have a couple ?'s

[charvel pointy head]

OK, got my next kit. Got a 69 kit but got the filter specs for 68, i.e. 3 dual 32's, a dual 16 and 2 dual 50's. How do you lay these out properly? I presume the dual 16 goes down by the preamp tubes, it's a v2 filter isn't it?

how about the others, particularly the 4 cluster area just to the right of the board? Also I see the slope resistor in the 69 is a 33k and the older models use a 56 k. is this why they have a more aggressive gain structure typically?

Oh, and screen grid resistors. they are like 1.5k in the kit instructions, but it seems like I put 5.6's on the tube sockets of my JTM45, and I believe you can use this value in the jumper for the 4 tube 100 watts as well. What difference would I see? These have something to do w/ oscillation don't they? would the higher value decrease this but at what expense to what quality that the 1.5 allows thru? Please advise?

Oh, and it's a purple box, as my 3 yer old says " its pipple"

My guess is this:

The two 50+50 cans go together for the mains. In the group of 4 holes, they would go closest to the PT. Parallel then in series to equal 50uF on the mains.

Two 32+32 cans go together for the screens, put them in the other 2 holes next to the mains 50+50 pair. Use only half of each 32+32 can, in series, to equal 16uF on the screens. (Alternate: Parallel and series to equal 32uF on the screens.)

One 32+32 can in the PI hole, in the corner of the amp. Use only one side to equal 32uF on the PI.

One 16+16 can for the preamp, under the board. One side filters B+ for V2 and the other for V1. So 16uF on V1 and 16uF on V2.

It easily could go differently, it's up to you, you can go dual 32s on the preamp and 16uF on the PI. Rockstah's 2203 is/was like that.

I'm gonna save rockstah the trouble of posting this, it comes from his collection of diagrams and layouts.
