I recently took the chance to acquire an Optimus CTR-117 cassette tape recorder (by Radio Shack or their brand at the time, Realistic). The specs in back of the manual are sparse, and important entries that normally get listed on spec sheets are omitted.
The only additional information I found was in a Proceedings of the Royal Society article, in which is written the CTR-117 was used by researchers, along with their WM-6DC Professional Walkman, for recording birdsongs. (BTW, I don't expect it to be near the overall quality of a Walkman Pro!) Is anyone familiar with some specifics of the CTR-117? Maybe even owned one? I'd be interested to know its frequency response, SNR, or just about anything else the manual doesn't tell me about it.
