Default psu2 problem

Hi I have a problem with my psu2 and phono 2 - while doing some work had a short and since then the phono plays music but not well. The heater supply gives about 5.8 V with no load and drops to 2.8V under load. I suspect the regulator in the psu - any ideas.

I would guess its either the regulator or the diodes that feed it. They are all cheap components, so I would start by replacing them.

thanks Nick - I have ordered the regulator and diodes as I have not got any in my spares box.
