|BH||Question: How to select a choke?|
I'm in the process of building my first amp and was wondering how to select a choke for a power supply.
I'm building a 60W Mark IIC+ power section from a Mesa schematic and was wondering what the choke value was for the power supply.
The schematic can be seen at
I have an actual MarkII power supply that has a 345-0-345 secondary. I'm not sure about the current rating. I didn't receive any information with transformer and had to measure the the taps myself. If I had to guess I would say around 200ma, but I have no idea. How can I measure that correctly/safely?
There is a 7 volt drop across the choke/inductor going from 480 to 473 volts.
Also, where is a good source of chokes? Hammond seems to have plenty.
