Prince '60s question

Hello all,

I have populated my Prince board and am prepping the chassis with ground lugs and sockets and pots, and have begun planning the wire routing. I think I may have found an error on the layout diagram, perhaps someone can verify with me. On the diagram, where the red and blue wires from the 220k grid leak resistors go to the power tube sockets, the diagram shows a blue wire marked on the board as V5/P5 going to V6/P5 and the red wire that is marked V6/P5 goinng to V5/P5. Should these be wired as to what is marked on the board ? Perhaps it doesn't matter, as the schematisc looks like the same place in the circuit, but I think it ought to be corrected to avoid confusion.

thanks for any help.

I tried to upload some pics awhile back, but I'm still navagating this website I guess. I've got a bunch. I was trying to find other peoples pics of this build to help with refrence on my build. The one pic I could find on here was in testimonials and it only showed half of the PCB board and chassis. The power section of the amp was omitted. LOL. And that's what I was looking for.!! This one 1/2 chassis pic had an Impendance switch too. WTH? Talk about adding more comfusion and deviating from the schemaitcs.

I'd be glad to post to help others tho and post pics. Please advise.

The main diffrences between the layout and the schematic, for one, is that the layout has a standby switch. Schematic does not have this. Layout also has 2 seprate fuses. One to mains and another to HT. I understand the logic to all of this, but the schematic didn't have it. These modifications were paired with the original schematic and this is in conflict. Leads to confusion. Another big one is the CapCan was deleted for 4 individual E caps were used in its place. Absoultly nothing wrong with this. Makes perfect sence, but it came with no explanation. Eventhough it does jive with schematic, it was confusing because in refering to other princeton reverb builds on the internet for direction, they always had the capcan.I needed to figure all this out on my own.
