Ipod in a Philco
#20

Ron Ramirez Wrote:I decided to take some time and put together a partial schematic of the 38-40 showing the Pbpix mod to add a 1/8" stereo jack (see below).

Full credit for this mod goes to Peter G. Balazsy, with his permission. I only redrew a 38-40 schematic below to show how Peter's mod can be used on a 38-40.

Ron - now that I have an operational 40-185 my next todo is to install an aux input for my iPod. I read through the thread you pointed to earlier and spent some time looking at the modified schematic you posted for the 38-40. The self-closing Radio Shack plug seems to make this a fairly simple modification, eliminating the need to add a selector switch to restore the circuit to its original design.

Looking at the schematic for my 40-185, I'm a little bit stuck on exactly where to break the circuit. On which side of cap #38 should i install the jack - where the red dot is or the blue? My theory is that it should be where the red dot is so that the cap provides some protection for the iPod as mentioned on the other forum, but I can't say that I can really defend that scientifically.

Thoughts or advice?
