Hi all...
I am about to build a HiFi amp for a friend as a wedding gift and I have the schematic ready and all but it seems pretty hard to find a suitable power transformer for the task.
I would like to have a bias tap (secondary) of around 50V or so and I also need two secondary windings for 6,3VAC @ 4A each ( a lot of heater current with two EL34's on each channel). Looking at Edcor it seems that I can chose between the two options but not together.
So... my question is if it is just to tap from the HT secondary to get a 50VAC tap? I have seen this in some guitar amp schematics and I thought I could do the same. Pros and cons of this?
Any input is valuable I guess
Best regards
/John
