Phantom Fried My D.I.!!!!(I Think!)

[maestro_dmc]

Has anyone done this or heard of it?

I have two of these old, beautiful handmade Direct Boxes I "inherited".

They are real sturdy, I think they must have been made in the late 70's, they have that look.

Anyway, they're both fried! I was using one to send Acoustic Guitar via pickup into the mixer for live playing, and it worked for several months. I think phantom was off because we weren't using condensers. Then it stopped working, I assume because we hooked up phantom power.

The other one was at home, and I didn't use it for a long time. Then I forgot about the phantom thing and fried it too.

I want to repair them, cause they're cool looking if for nothing else, but I don't know what I'm looking at inside, or what to replace.

I can solder fairly well, but I don't really know where to start.

I'd like to post a pic if I can figure out how.


Anyway, be careful with those old Direct Boxes!!

If you can post a pic - I may be able to tell you what you're looking at, and if you have a meter, what to measure.
Most DI's have protection, but as you say, if these are from the 70's they may not.

Too bad, but hopefully they can be repaired.
Cheers,
Mike

DIs are by no means complicated. Take some pics and show it to the people here or in a DIY-amp/preamp forum. There are a lot of guys there who build their own preamps, monoblock power amps, etc and they'll let you know where to start.
