Overview: A simple monaural cassette recorder that can only record from the built-in microphone. However, this unit has the critical flaw of extremely quiet recorded and played back sound, and the preamp is built with discrete components, and to top it off, there is no service manual. Due to this triple whammy, junk units are listed in large quantities, but almost no serviced units are available. We have independently analyzed the circuit and fixed the defect of extremely quiet recorded and played back sound. Features: ・Microphone sensitivity switch ・Tape counter ・Fast playback ・Cue & Review ・Automatic stop at tape end during recording and playback ・External power terminal (3V, EIAJ#1) Repair Details: Please see images 5, 6, and 7. Notes: ・Only the main unit is for sale. Please prepare recording tapes and two AA batteries separately. ・There are fine scratches and scuffs throughout. Please see image 4. ・We are the only ones who have put this much effort into this unit. We will ignore price reduction requests unless a competitor appears who performs the same maintenance and lists it at a lower price. We will gradually lower the price when we feel like it, but the lower limit is 3200 yen. ・This unit is a monaural tape recorder. When headphones or stereo earphones are connected, sound will only come from the left side. Single-ear earphones will work normally with 2-pole, 3-pole, or 4-pole plugs. ・We do not list monaural cassette players. If you are looking for a monaural unit, please search for cassette recorders.
