Thanks Aaron, what do you use to tack wires to the chassis. Quick drying silicone? Any particular brand. I have had some silicones that seem to never dry. Maybe hot glue gun?

I use 3M stick on squares like you have, or UV-cure adhesive, and in rare cases, hi-temp hot glue.

Aaron, I have the preamp grounds on a bolt that the choke is using, should I move that or will it fly?

You're using a bolt that secures the choke to the chassis as a ground point? OK, I guess.

[angelodp]

Yes, its in the right spot. Just wondering if there might be any current through that connection that would induce hum.

No current in the metal housing of the choke--it will be at ground potential.

Very kind, sorry to keep pulling you away from work.

Don't be silly. I live here.

Gonna populate board soon.... I know very slow boat here.

So my understanding is that with a PPIMV dimed its essentially same as circuit with 220k's no PPIMV (In a Marshall SL 100W) True?

yes

When I run the PPIMV wires, my plan is to shield the pair of wires that run to the 220k spot and 5.6k's terminating the shield at one end. I know the shield can be used to run the bias wire as well. If I go by the Metro layout and use a separate wire for the bias run, should that be a shielded wire as well?

No, the bias does not need to be shielded.

Perfect thanks Aaron.

Aaron, above board jumpers, I am thinking teflon 20g or 22g.... yes?

[xtian]

Which jumpers? What function?
