pkautzsch Posted November 13, 2012 Report Share Posted November 13, 2012 Dear community, I would like to make a simple "T" power supply for my old 416T, intended to be used on a wireless boom. I don't want to use a barrel style adapter, as that kind of adapter eats up lots of power just to convert the P48 to T12, and I don't want to be changing batteries on a plug-on TX every hour. Plus, using external power would allow me to use basically any TX. I already have a lightweight 12V Li-Ion rechargeable (which actually gave me the idea for that project), so that's no problem. However I can't find any reliable diagrams on the web, they all show the 180 Ohms resistors but differ widely in coupling capacitor values. Any pointers? THX in advance Quote Link to comment Share on other sites More sharing options...

Well, mine makes a plug-on TX last about half as long as with a P48 mic. Anyway, any hints as to capacitor values? Quote Link to comment Share on other sites More sharing options...
studiomprd Posted November 14, 2012 Report Share Posted November 14, 2012 " hints as to capacitor values? " OK, hint: PSC makes the popular adapter barrels, and products that support "T" powering, SD still makes a product that supports "T Power". ... now <cap> Quote Link to comment Share on other sites More sharing options...
Ruben Rojas A Posted November 15, 2012 Report Share Posted November 15, 2012 Take a look at the Ambient UMP II power supply, it might not be an inline adapter but I think it would work good in a pouch for your boom op, works with AA's. I've posted this on other threads. Quote Link to comment Share on other sites More sharing options...
