I have a box full of old reel-to-reel tapes and the original 1951 Revere T-100 they were recorded on and would like to transfer their contents to digital. I'm not worried about the actual process - I have and know how to use Sound Forge, but I am having a hard time figuring out what I need to do to connect this unit to the PC for capturing audio.
The issue is that there is no line out or headphone jack on this unit - the only output is a speaker jack. It is a tube unit and I have no idea what the output impedance or voltage might be, so I'm guessing that connecting this directly into my sound card is probably a really bad idea. I have attached a schematic of the unit if it helps.
Does anybody have any suggestions on what kind of interface I need to keep this thing from frying my sound card? Maybe an isolation transformer of some sort?
Thanks in advance!
