Re: BA BA2 BA4 BAD Dual99v Build Thread

They say 36x, I tested them to see if they measured the same voltage drop that the ones i know work have.

Re: BA BA2 BA4 BAD Dual99v Build Thread

Hi Joe. Im building a couple of BAD. And i have a couple of 600,600 ohm transformers. Similar to the JENSEN JT-MB-D,,,i was wondering what issues besides lower gain i could encounter, Higher noise floor? Mi plan is to use both stages with 5532. Maybe change the Rgain to recover the gain? I ask, beca...

Re: Passive Controller Build Thread

Hi Joe. I built the monitor controller + Vu buffer on the same unit. Everything is working perfect! But the DIM does nothing, i installed 5k resistors insted of the trimmers. Do you have any hints to troubleshoot this?

Hi Joe. I ordered a couple of BA pcbs from you and im stuffing them right now. There is a 10 Uf cap i dont see in the schematic. What is it for? And another question, the 470 uf cap that goes into the 6k8 48V resistors (the one sitting right over the 470 uf/ 330 uf 63v one),,,,could i change this on...
