    PAS 2 Power supply

    Post by Kinski on Wed Jan 10, 2018 5:10 pm

    Hi,

    I'd like to replace the stock can cap my PAS 2 has. Is there a benefit to the higher value caps of the any power supply boards sold? My original can cap is 20/20/20/20.

    are you having any particular issues with your current multi cap?
    There are a number of 'non multi cap' power supply upgrades available.
    If you are interested, 'pm' me.

    There are any number of after-market power-supply boards, some regulated, some not. A few of them will allow you to bypass the 12X4, which is a very good thing as it reduces the load on the OEM transformer.

    Some of them give you a second filament transformer as well, allowing you to keep the 12X4. But, on another thread we are discussing such a board that may have failed for reasons as-yet unknown.

    I am using a board on my "second" PAS-3X that does remove the 12X4 from the circuit - and some months down the line it is still working very nicely. It took about an hour to assemble and install.

    Prices can vary from ~$50 to ~$200.

    One additional thought that might be of interest.  I get the impression that switching to a cap board in a PAS can be a little tricky when it comes to proper grounding.  While I tend to favor a cap board, a replacement quad cap shouldn't have any added complication http://www.dynakitparts.com/dynakit-products/capacitors/MULTI-SEC-ELECTROLYTIC-CAPAC
