Hi guys,
I am starting the mod of my microphone after researching a lot around i got some parts from AAmicrophones.
Dave has been very helpful providing the parts and now i am facing some issues.
I am starting with the circuit, i removed C6, C7, C9 and C10 and i have swapped C8 for a 2.2ufd
I have taken the Transformer out and i will be putting the new one in... it's quite difficult to get the cables around since the leads from the BV8 are very short... i have to clean up a bit.
Now i am looking at the power supply.
Dave sent me a Zener diode which is 1N4754a which should be 39volts.
THough the one on my PSU, D5 and D6 are respectively 1N4782A (82volts) and 1N4780A(68volts).
I don't know which value i should be ending with and which Zener diode to change... Maybe both? or should i swap D6 with the 1N4754A and get a total of 121 Volts?
This voltage should be bringing down a bit the harshness from the capsule i heard.
Finally i will be trying the mic with the stock capsule before installing the K47 one...
I would greatly appreciate if you guys could help with that Zener diode and any other tip...
