[1100 man]

So how comes your chassis looks like it's just come out of it's delivery box? It looks brand new!!
Thanks for the dismantling tip: I wouldn't have thought of doing that, but it certainly makes the initial clean up easier. Mine seems to have an oily residue over much of the upper part of the chassis and back of the tube- from the LOPT I assume.
Talking of which, are LOPT's particularly problematic being oil filled? Do they suffer from the same moisture ingress problems as 'dry' ones?
The worst problem with my set, and the main reason it was given to me, is the tube mask. It has drooped & sagged at the bottom and there is a large gap between it and the tube.
However, I'm sure my bodywork colleague will be able to do something with it:- he's a dab hand with fibreglass, body filler and paint.

To answer Frank's point in post no2, this set does not have a fine tuner. They must have been very confident of their local oscillator stability to consider not fitting a fine tuner!

All the best
Nick
