GB F5X Amp final build Cases

Waiting for Morde to test. He already has new PCBs for that.

The diodes under test are 3-pin TO220.
It has a lower forward voltage, which reduces dissipation in the regulator heatink.
You should then run the regulator as pure cap multiplier (without the Zener).
The amp will see a fraction of a volt more rail voltage.
So no issue.

If you want to try in parallel, contact Morde for PCBs and details.


Patrick
Just want to check and see if there is any update on the diodes and your findings.
 
I have been lazy and also a house building project ongoing so I haven't changed the rectifier diodes yet. The new PCBs designed by Patrick are waiting in my drawers...
The amp works perfectly with the original diodes, just a little bit on the hotter side. If I remember correctly the regulator sinks were at ~65 deg C after one hour.
