Default TDA1545 v TDA1543

Hello.


Can I replace a TDA1545A [blown up] with a TDA1543 ?

They look to have the same pin-outs.

The only area where seems to be a difference is Vref and how it is obtained?

Otherwise, anyone know a UK source for TDA1545A ?

Andy

Or maybe get a cheap Philips cd723 from the auction site. (Although you knew that already.... unless you never read the service manual you sell).

Time to close the thread.

Thanks to all.

PS It's not for me + I don't pull working cdp's apart unless for modding.
