You will get the best audio from the diode output terminals on the strip in the back. Need to bring it to a decent amplifier and then good speakers. Sound fantastic on AM. 73 – Mike

Subject: [Milsurplus] WTB: Speaker and headphones for R390

Guys,

I am looking for a pair of good headphones that will work with an R390. The impedance needs to be 600 ohms, or I would also need a suitable matching transformer.

I am also looking for an old style wall mount PA speaker, like the wooden ones you saw up on the wall in old school classrooms. From what I understand, some of these are already 600 home and wouldn’t need any additional transformer. But if you have a speaker that is not 600 home and a suitable matching transformer, that would be great too. Please reply here with a price, or if this is too off-topic for this list because there are no military items like this, then please email me at [email protected] with a price. I looked at fair radio, but I didn’t see anything on their website that would work for me.

73,

Mike Veach
