Buy Joe's 48V SMPS. My recent V72 racking:

Thanks for the explanation. It was my first assumption that the plot is a result of using an 2604 here. Will exchange them with DOAs.

Thanks Joe. I've recently went to a local EE audio company to get some test results for the combo unit. The BabyAnimal has an EIN of -117 dBU at max gain, 20-20000 Hz, 150 Ohm terminated. This is, IIRC, 10 dBu worse than the theoretical possible EIN of -127 dBu. Here's the AP plot for the BA (Lundah...

Q: Anyone make a preamp / compressor combo unit? A: Yes, me. Built it for a local musician for his home studio. He wanted a dual pre/compressor unit, I left out the first PreAmp because he decided to buy a tube preamp for his voice channel, so this is a one PreAmp/two compressor unit with an option ...

I've decided to make a new front panel for my MAC 500. Custom painted green, looks a bit like an old Altec device



I can recommend to buy one of Joe's compressor kits.

I finished my first INX5 today, used here for a MAC with a nice Haufe transformer.

I don't know why it works but it works
Thanks.

Is it possible to run a BA on +/- 24V just as a gain stage with input transformer and DOA ? I don't have 48V in the box I'm currently working on.

Very nice Joe. Seems that you've been very busy the last weeks...

Joe, for those who alredy built their meters, can you indicate the position of the relevant components on a photo?

Regarding R1 on the little PCB: what value goes where (lots of holes)?

Here is my API 500-compatible version: http://audiofor.tv/diy/jlmmeter/front.jpg http://audiofor.tv/diy/jlmmeter/finished.jpg Metal work (sunny afternoon with my Dremel): http://audiofor.tv/diy/jlmmeter/metalwork.jpg I used the L-bracket and the little connector PCB from the 51X Audio guys. You can ...

I will, but still waiting for the first panel. I'd like to show pictures rather than drawings.

It's available in the shop now.

Chris, I agree, it's a big meter. But I see the beauty in the logic behind it. Joe uses the big dual/triple colour LEDs, I assume that it would be possible to use smaller, single colour LEDs later, thats why I'm wondering about different modes. So, once Joe and his team has developed the software fo...
