This is probably one for Arfa.

An old friend asked me to take a look at his Roberts Radio R303, I`d
usually say no, but, well you know how it is!.
It's not oscillating, I imagine it's the old AF114 promble, shouldn't

be
too much trouble to mend, but how the hell does one get the chassis out

of
the case?
The only way seems to be to take out the battery cradle and speaker,

which
looks difficult with the circuit board in the way, or am I missing
something?

Hi Ron

What Mr Cook says below on the problem and its 'fix'. I actually used to
'blast' the internal short off the transistor, by momentarily shorting

the
transistor base to collector :-) ...

On getting the chassis out, is it by any chance one of the ones where

the
top part is secured into the case by screws at either side, which are

also
the handle pivots ? If so, the handle clips off on spring-loaded

'keyholes'
and then the pivot pins revealed have a screwdriver slot in them. Once
removed. the radio withdraws from the top. Could be thinking of an

entirely
different model of course. Old grey matter is not what it once was ...


Thanks arfa, I`m aware of the AF114 internal shorts, even way back in
the late 60`s it was happening, sometimes flicking them with a finger
nail would get them fired up again, temporarily at least. I used to snip
the screen wire.

The top of this radio seems to be glued to the case, the handle is
fastened on with spire clips directly to the wood, the chassis is held
in by two thin plywood strips in grooves, removing these allows the
chassis to slide backwards (downwards) but obviously the speaker is in
the way, the lower nuts holding the speaker in are somewhat inaccessible
with the chassis in the way.
