I need a choke for tube preamp PSU. A common mode choke, 2 x 5H, 100mA.
There is local workshop which supplies transformers, custom made (E-I Core). They will supply any transformer I may need. Alas, the owner has no clue how to calculate a choke. He'd supple my one, should I mention the core size and number of turns.
Searching the internet for calculating a choke brought up nil practical results.
