Hi,
I thought about replacing the zeners in the Apex 260 PSU with 62v zeners. However, I have a couple of questions...
- Is it possible, instead of swapping the zeners, to add a trimpot after the the two zeners, and adjust the B+ more precisely? If so what ohm value trimpot would work for this?
- Or, can the two zeners be replaced entirely with just resistors? To lower the voltage more like in an unregulated supply like an original U47 or C12. And are there any sonic advantages to this.
Thanks
