I am preparing Audio amp using, TBA810, this PCB require 12-0-12 V and
1-Amp Transformer, I have purchased2-Amp 12-0-12 and this has only two O/P terminals(i.e +12 -12 There is no Zero) Can I connect 0 terminal of
PCB to body of transformer? One other thing , Can i subsitute X-mer of
12-0-12 2-Amp With 9-0-9V 1.5Amp.Thanks Wasim Shaikh
A 12-0-12 transformer wil provide about 16-0-16V DC since the power supply capacitors charge up to the peak value of the AC voltage.
The 9-0-9 transformer will be the one to use.

--- No.
If your PCB needs 12-0-12V that needs to come from a 24V transformer with a center tap because the power supply on the PCB will [more than likely] look like this: (View in Courier)

--- If it doesn't have a center tap, no.
If it does, you won't be able to get full power out of the amp.
Why don't you just get the right transformer?

Ditto that. get the right transformer or wind what you need.
