Hello, Tim: Yes. I thought so too.

Actually, in order to even SEE the filament in any of those battery tubes, you have to be in a 
darkened room and get VERY close up to one.

Sigh...... :-(

Yes. Just solder a phone plug on the end of a short piece of coax and plug into the phones 
jack.

BTW, I have been working a lot of stations on both 20 and 40 with my GRC-109. It sure is 
great fun. I have added one of those very small Radio Shack audio amp/speakers. It makes 
a huge difference in how easy it is to copy signals.

My R-1004 has very weak audio output. Not sure why.

Also, when I turn the RF gain all the way up, that pulls the HFO noticeably.

I replaced the selenium rectifier in one of my power supplies with silicon and a resistor a 
LONG time ago.
