Re: BA BA2 BA4 BAD Dual99v Build Thread

Hi Joe, Can the DI or it's ribbon cable have something to do with it? I looked at the ribbon and it seems kind of tight in there between the VTX and the back of the DI pcb... There seamed to be a tiny tiny hole pierced in the ribbon by the slightly protruding capacitor legs at the back of the DI pcb...

Re: BA BA2 BA4 BAD Dual99v Build Thread

Hi Joe,

You're right it's not quite a short. (I was checking with continuity setting on my meter, with a "beep")

I have 15R accross tranny primary and 30R accross XLR pins 2 and 3...

Re: BA BA2 BA4 BAD Dual99v Build Thread

Hi Joe,
Thanks for your response.

The 51R next to output pin of 99V is looking burnt(brownish tint) but still measures 51ohm(in circuit).

I also noticed that +OUT an 0V on the BA are shorted... That seems wrong to me, wright?

Re: BA BA2 BA4 BAD Dual99v Build Thread

Hi, I have a BA2 "everything kit" with 99V and VTX trany. It worked fine for the first few weeks and then one channel stopped working and fried the 99V. (I thought the problem was caused by a faulty power supply at first). The 99V was replaced and it worked for about a year. Now, it seems to have do...

Re: BA BA2 BA4 BAD Dual99v Build Thread

OK Joe,

I'll just make sure the right power supply goes with the right mic pre.

Thanks again.

Re: BA BA2 BA4 BAD Dual99v Build Thread

OK :roll: :lol: That explains it all. I had'nt seen the "Notes & Errata" about this since I build these BAs(&BAD) before this issue showed-up on the forum. They had all behaved correctly until I inadvertantly swithched the supplies... I'll perform the mod to all my BAs. I think the "soft start" opti...

Re: BA BA2 BA4 BAD Dual99v Build Thread

Hi Joe, A while back I build a BAD (with a pair of JH99C and Lundahl 1538) that has worked great until recently. When I power it up it goes into a cycle of "power LED lights up and slowly ramps down" (sawtooth like)at a frequency of about once a second. If I pull the +48v feed off the BA and re-ins...

Re: BAN Build Thread

Excellent Joe! - Can you (or anyone) offer up any thoughts as to what differences to expect with the use of different opamps and transistors? (Is that a MAT02 I see in the webshop picture?) - Do you have schematics and a wireing overlay PDF available yet for the BAN? - Do you offer the listed altern...

I personally would prefer a one U rack size.
It would be unique for a stereo optical comp.

However, nothing is stopping you from putting it in a two U rack along with a pair of BAs. :wink:

Just my thoughts...

LED VU meter - anyone interested?

Hi All, I asked Joe about a LED VU and here is what he said he's been working on.
