Hi all,
Just a quick question.
I am a building 6N16B Sub-Miniature SRPP circuit for an output stage of CD player.
B+ is 200VDC.
Transformer -> BR1 -> CRC -> 200VDC.
6.3VAC for heaters also (no hum at low current).
230V - 140VAC roughly equates to 200VDC.
Happy with the power supply scheme.
Very low current draw.
What if my transformer was either:
- 100VAC secondary (too low after converted to DC still)
Or
- 300VAC (too high to start with)
How would you scale up or down?
Or would you go with the 140VAC to BR1 route as simpler from the start?
Thanks,
Luke.
