Zener diode B+ dropping question - allowable distance from voltage source?
Posted: Wed 03/27/24 3:25 pm
I've used the zener diode method outlined here successfully in the past to drop B+.
I'm currently working on an amp that would benefit from the same treatment, but there is limited room to place a turret and a couple zeners in the capacitor area. It would work better to have a wire run leading to the turret and zener, then straight to OT from there.
That has led to a general question about the zeners and their implementation - Does the zener have the same effect when placed further away, closer to its intended destination, the OT? Any concern about the wire run? My instance only needs the zeners to affect the OT point to get plate voltage down, nothing downstream needs voltage reduction, but for completed reference, would a wire run back then to feed the next stage be problematic?
I would think it is all fine, but doublechecking with those that have more experience implementing the zeners.
