    KEF Corelli speakers. Just giving these little things another go after unhooking the big Tannoys. The transparency of the Corellis is quite remarkable, especially when you consider their simple design and forty year age. I have the original Monarchy Audio SM-70 (not the Pro version) power amp driving them and the way you can hear deep into the recording is uncanny. I was playing some 'Biosphere' and the huge ambience came across superbly.

    That's very disconcerting. I was playing Sharon Robinson's 'Everybody Knows' album on CD and noticed some bass distortion on right channel whilst playing the title track. I thought 'bugger, a rubbing speaker coil'. So I took the bass driver out of the Corelli and checked it over. Seemed OK, put it back and played the track again, distortion still there, so I swapped the speaker leads over. Sure enough, distortion on left now. It's on the bloody recording!!

    Oh dear, my Pioneer PL-61 has fallen apart.



    Seriously though, I'm going to try and resurrect this. The arm is knackered, the anti-skate mech has been busted at some time, not uncommon on these I gather, frail plastic innards. Not to worry, I was thinking of installing another arm anyway.

    The main turntable section seems all good, apart from a deteriorated thrust pad under the main bearing spindle. The bearing itself is super quality, full length bronze bush in very nice condition and a snug fit with the spindle even without lube.



    Dunno which arm to fit though. Jelco SA-5, Linn LV-V, Decca FFSS, Helius Basic or Mission 774. Might go with the Helius, as I've never used it and it is the original first model, which was quite well reviewed.

    The innards. Check out the size of that Hall Effect motor.

    The remains of the old main bearing thrust pad. Looks similar to Tufnol. I'm just going out to the workshop to make a new one.



    When I took it apart, the bearing was packed with thick grease and the spindle was very resistant to turning. Somebody used the wrong lube at some time. There are 'mole grip' marks on the bearing base cap. I'll remove the offending marks and lube with decent oil. Gonna need an 'O' ring, biggish fibre washer or silicone sealant to stop oil leaking, I'll suss that out later.

    The new pad should be fine, but if the Tufnol wears, I'll bung a brass one in.
