I have a very old valve radio from a company called Lafayette.
It has 6 valves which are
6v6 gt
6x5 gt
6sq7 gt
6sk7 gt
6sa7 gt

This radio was working fine but recently has developed the following
problem, when the volume is increased the sound is distorted
completely,
it can only be heared ok when the volume is very low, and putting the
ear onto the speaker. Any ideas?

Sorry, I accidently posted it to the wrong group.
To add to the above, it is a MW/LW/SW type
and the problem occurs on all of the bands.

Thanks in advance.
