Yes, that's why I had you change pin 1 from chassis ground to PCB ground.
BTW, the Balanced version has very low THD, sounds great and is silent.

Are you talking about a VRDN board run or BA2018 board run? VRDN is awesome and completely worth the effort. Works wonderfully with BA2018.
However, you probably want to ask about it in the VRDN thread…. 🙂

Both are needed 🙂. But I was just replying to the post above making a point to pool resources if something is needed.
Nice. 😎
The BA2018 PCB are available in the store currently. Completion kits are sold out, restock will likely be late spring. There’s nothing on that board thats particularly difficult to source, so start a Digi-Key order and go for it.

I will. Ba18 has definitely grabber attention.
I wish the store would have an alternative to DHL shipping options 🙂

I have a finished working circuit that has become redundant, if you are interested.

This pre has been totally silent with all poweramps I have tried, including the BA-3 (25-30db gain). So those issues are unlikely related to gain alone 🙂
If anyone needs BJTs, I have hundreds of the small TO-92 ones.

Too much gain? Probably not. It will be more than you need, strictly, but wont be so much that it’s causing problems.
Build it, you’ll love it.

You can adjust the gain on the BA2018. I adjusted down too far then back up slightly. I do not remember which two resistors I changed. I think Mark Johnson mentioned how to do it in this thread. Search all his posts in this thread. Wayne also verified the change.
