Re: TX98 Blown up power supply
It is running hot because the PSU is not running normally, ie. it is attempting to run from the start up supply.
The TDA4600 PSU is very well documented and has several known stock faults.
The earlier TX100 used the same Thorn derived SCR start up circuit as this TX98.
This PSU is very similar to the TX100 in respect of its design, look at the circuit descriptions of the TX100, TX99 and TX98 as they were all very similar.
