Another PSU question.
Here in South Africa our 220v mains are actually 235v. Now instead of getting 80v D.C. after my rectifier , I get 90v.
Questions:
1. Is this a big problem?
2. If so, can I just add another zener to the pack, each side?
3. Must I use 7 x 9.1v zeners, or can I use for instance 5 x 12v zeners?
4. On my Aleph30, still waiting for transformer, I must have 25v on rails, but will now have 30v, any problem with this?
Thanx to all.
