Hello, currently I'm running my caiman on a good quality linear PSU (ripple <0.3mV) at 13.2 V

I know the optimum voltage should be 15, but since I've done the passive mod, this is not an issue because the 7812 is not used, and I can say it is working beautifully

But I've a couple of question

1) is the 7805 feeded by the 7812 or from the main supply? I can read 9 volts on the 7805 input pin; may I eventually feed the 7805 with the main 13.2V?

2) Let's suppose I want to bypass the 7812 and eventually feed the analog board (the stock 4562 or a gator) directly with the main at 13.2; I'm going to burn something or is it ok? I've already done this mod on my previous 7510

thank you for your help
