Hi everyone,
I have a question: how do you select an output transformer for Stax headphones? I’ve built a circuit using 2A3 tubes, but I’m having trouble with the output transformer because I don’t know how to calculate the specs—though the LL1660 is said to be suitable. I want to order a custom transformer for 2A3 and 845 tubes.
Hi
I'm trying to power up the srx and i have a problem 😕 ....
I set the balance to 0v but when i'm triming 500r pot nothing changes (set voltage to half of B+)
I set 1,3MmA, 7mA, 17mA and i have 170vDC on output
I hear music but i hear a loud buzzing noise 😕 louder in L than R but whole amp is buzzing
