    Source components for M2 network

    Hi all!
    I decided to try the network on my M2 clones after "riding bareback" for 2 years.
    I have a hard time sourcing the components. Especially the resistors.
    Anybody knows a good source?
    The components are

    Capacitors
    3.3uF 250V
    4.7uF 250V

    Resistors
    13R 30W
    11R 10W

    Thanks!

    caps are WIMA MKP10
    There are different models in this series, with different tolerance rating and leg spacing.
    IIRC I got mine there: https://www.ebay.fr/usr/electricslee...72.m2749.l2754

    As for the resistors, I used 3 of these 39 ohm 25W resistors in parallel for 13 ohm (75W) and 2 of these 22 ohm 16W resistors in parallel for 11 ohm (32W).

    Wattage rating is very relative, and can be exceeded on peaks, but here is a comparison:
    The original lpad with 30W/10W resistors can take around 50W in, resulting in about 6W into the D2
    This version here with 75W/32W resistors can take around 120W in, resulting in about 15W into the D2

    voltage rating

    Thanks a lot Pos
    How critical is the voltage rating of the capacitors?

    Not very critical at all!

    OTOH, some people presume ( myself included ) that higher voltage capacitors can sound better ( it's a very nuanced difference ) due to their construction usually employing thicker parts and a tighter wrapping technique ( so goes the lore ) resulting in a capacitor that's slightly less prone to micro-phonic resonances ( as one plus ).

    Per Thomas, if you use your 2450SL's you will need to add an autoformer

    Here is what he recommended:

    I've been using this for a year or so now with good results. He had super fast shipping and excellent communication.

    Thanks,
    Scott
