    LP12 Refurbishment - do I need a new top plate.

    The linn supplied plinths are lacquered/varnished and to bring out the colour of the timber its not clear but usually a golden colour like golden pine.

    Flux removal from PCB

    I use isopropanol and a tooth brush but find the trick is to dab it it up before it evaporates into some kitchen roll also plug or avoid any though holes so there is no run through.

    LP12 Refurbishment - do I need a new top plate.

    That's the earlier type top plate but not the earliest which was thicker, the later one is pre bent so it has 2 dips across it not one large one and as a consequence the deck is easier to set up.

    Naim Nac 32 to 32.5

    I did a 42 and just one cut track was all that was needed, right where the red power wire joins the board. easy peasy.

    Nap 250 cable to 135

    The later 135 cable was the same 3 core wire but with the unneeded core cut off at both ends, I presume so it doesn't act like an ariel.

    Linn Isobariks - replacing the mid and bass drivers with Falcon units

    If you can, leave them playing quite loud with full range signal for a few days. you can do this with the two speakers facing each other a few inches apart and some blankets over them if continuous noise is an issue. The wool linn used is very good and will have been weighed to the...

    Nap 110 amplifier board failure

    Great little amp the 110, part of the charm is the bdy56/naim002 power transistors used.

    Nap 110 amplifier board failure

    It will be fine to run just one amp board to check the ps voltages ,should be about 35+ 0 35- dc. bare in mind the reservoir caps might still be charged with no load ie an amp board attached. I sounds like you have shorted a power transistor as the 3 w wire wound resistors have heated up...

    Nait 2 casework refurbish

    It's not a powder coat finish. when the sleeves look tired its usually household polish deposits, to remove them submerge the sleeve in warm water and fairy liquid for 10 minutes then a nail brush round and round. If it still looks tired you can give it a dusting of matt black aerosol paint.

    Need some wire for B139s - Linn Isobariks

    Hi , m5x 0.8 is the standard m5 thread as apposed to m5x 0.5 which is m5 metric fine thread. The 0.8 and 0.5 mm is the pitch in other words how close the spirals are to each other . Neoprene foam sheet is good idea as refitting the rear bass unit on to bed of silicone is tricky to get...

    if they are m5 the bolt head will need an 8mm spanner/socket

    Need some wire for B139s - Linn Isobariks

    Having rebuilt at least 4 pairs of briks I am sure the bolts and capscrews are m5 x 0.8, also the bolt head covers for the bass units are hot glue to seal the air in the chamber.

    I think they were originally made with radio spares 2.5 mm 50 strand.
