Re: Noisy MDV

The DeOxit is an excellent contact cleaner and lubricant for contacts - but not the best choice for general lubricating. As you said Derek - a good "light oil" is what's needed, but I think 3-in-1 may be too much even. Generally lubricants intended for watches / sewing machines etc would b...

Re: Noisy MDV

This is the stuff I use - excellent lubricant for small engineering projects, motors, etc, where you just need a small amount.

Re: QL not booting if case screwed tight

almost certainly 'flexing' of the main board is probably exposing a dry connection or a chip not seating properly in a socket. Remove Ic's that are socketed - clean the legs with a deoxidizer - the stuff people use for their guitar jacks is excellent but expensive and re socket them. Try the board a...

Re: Today I Received...

I was born just down the road - and moved away then came back to live in Camberley for a while. I remember sending a QL back to that address for repair - and got upgraded ROM's out of it :-)

Re: Today I Received...

I wonder where that was - as the postcode is no longer registered - no 3BR - but there is a 3RB on the high street.

Re: In the market

For most of the older QL's I've seen - the caps are usually in quite good order - the only ones you may want / need to look at are around the supply circuitry behind the Microdrives and under that heatsink. Membranes can still be had new for about £15 or so and not too difficult to replace, it's usu...

Re: Noisy MDV

I had a noisy microdrive and resolved it using some 'slug slime' - a fine modelers lubricant - just a drop on the top and bottom of the motor, and run it for a while - it should quieten down.
