Martin Taylor fitted one of the first batch of Bearing Base Plates that I made using the bolting method rather than the epoxy method now used.
He lives near Newbury I believe.

Hi Mike,
Done! :)Quote:

Marco.
I know I'm more than competant enough to do this myself. I fitted my external psu, Mike New bearing and ETP platter without any issues. The bearing baseplate 'feels' a bit more involved going by the instructions I received with it and the instructions and pics on this thread. I really dont think there's much margin for mistakes with dismantling of pcb and gubbings, drilling, gluing with strong epoxy and putting pcb and bits back. I'll tackle it soon as I'm sure it will be a very worthwhile upgrade :)
You’ll love the effect, Rob.
I mean just look at how little of the chassis is properly supporting the bearing, without the BBP in place, as it teeters on the edge of a big hole, ‘floating’ rather precariously on top of three raised screw threads:

How can that possibly offer a secure foundation for supporting the bearing? It is a fundamental weakness of the Technics, and as is shown below, the BBP solves it:

…by allowing the bearing to sit flush on top of the chassis, and thus be firmly coupled to it, as is the case on all other properly engineered high-end turntables, such as for example, on a Garrard 301:

The difference this makes over the stock arrangement on the Technics, in terms of bass weight and authority/lowered noise-floor, has to be heard to be believed!
Marco.
Thanks much Marco!!!
I agree Marco. The stock arrangement is certainly not ideal for something as robust and well engineered as the MN bearing.Quote:

One on each side of the board, (top, bottom and right hand side, when viewed from above.) Note: you may need to clip the cable clamps on the bottom cable form to give more freedom'. Any pics showing this would be much appreciated. As you can imagine, any f ups during this job could prove costly so better extra safe than sorry!
On a side note. I'm beginning to realise even more just how involved this is and that the pcb and all the wires (basically all the Techies gubbins have to come out and then be re: attached). I'd appreciated advise on the easiest way to do this. (I dont like messing with loads of wires, for fear of mixing them up, plus having to put them all back, but in this case I know I have to and so be it)
One tip, Rob, with wiring, is to take a nice close-up picture of things as they are before you start the dismantling process, then you have a guide as to how they should be when you’ve finished.
Sorry I can’t help you with anything else, but good luck! :)
Marco.
Great idea Marco - Thanks, Will defo do that. Looking down at my pcb with all the wires / plugs attached, I can see that I basically need to carefully unplug the plugs from the pcb and unsolder the wires which come from the external ps to the circuit board as per the instructions. Then unscrew the three black screws which hold the bearing in place and carefully lift the circuit board upwards and remove the bearing. Not gonna rush any of this. Pity it's dark now as I have to be at my sisters for 7pm to celebrate my twin niece and nephews birthday so I'll tackle this a bit at a time, as and when time permits :)Quote:
