    PAS3 Power Supply upgrade, PC5 B+, 16 help with confusion.

    Post by Reptiled on Sun Feb 17, 2013 6:37 pm

    scratch I am on step 20 of the upgrade instructions (tube4hifi) and it asks me to connect B+L to eyelets 16 (PC5). There is a black wire coming from the quad cap connecting to eyelet 16. Should I remove the quad cap connection to 16 or do I keep it in place? Do I remove the quad cap entirely at this point?

    I'm about to do this very same mod soon. I've never done this mod before so you and I are in the same boat, sort of speak. The only thing I can answer is that the power supply replaces the selenium rec and the quad cap. Once the quad cap is disconnected, you can remove it or leave it there for that added retro look.

    Note: Did you discharge the quad cap first?

    "Note: Did you discharge the quad cap first?"

    Naw, I snipped away. I was very careful though. pale

    If you would like an answer to my question above, here is what Roy Mottram responded to my email with: "you should remove ALL wires from the quad cap since this board is replacing that, although there may be some ground wires attached there that can stay or be grounded somewhere else on the chassis. The old quad cap can be removed or just left in there."

    Which is what I thought. Better safe than sorry...

    I was going with the discharge method, but your way sounds easier. What did you do? Snip each + wire one by one?

    On second thought, by snipping, the quad cap would still have a charge. Shocked I'll go back to my original plan.

    Your original plan would be best. I measured the cap after I had it out and it was hot.
