Re: British TV sound IF Frequency
Hi Frank,
As John says there are lots of 50s sets with 19.5MHz sound IFs and a few with 23.5 MHz.
The nearest to your needs is 21.5 MHz which was used on English Electric model 1550 and 1550M for channel 2 and 4 reception areas. The Channel 1 sets had their IFs tuned to 20 MHz.
I suspect it would be easier to modify something else than to track down a 1550.
Peter.
