There's a guy on Facebook Marketplace near me who is selling a MT-2 with the following mods,
Basic Modification Strategy:
Basic circuitry is well-designed so no fundamental modification
Remove electrolytic capacitors whenever possible
Use high-grade electrolytic capacitors whenever possible
Semiconductors:
LED1 (CHECK LED): 3mm red (LN-28RP) -> 3mm bright blue LED (E1L33-3B)
Q1: 2SC3378-GR -> 2SC3113-B
Q4: 2SC3378-GR -> 2SC3113-B
Q7: 2SC3378-GR -> 2SC3113-B
Q8: 2SC3378-GR -> 2SC3113-B
Q10: 2SC3378-GR -> 2SC3113-B
Resistors -> Current Regulative Diodes:
R2: 10kohm -> Semitec CRD E102 (source follower load)
(Semitec CRD E102: Current Regulative Diode, 1.0mA,
replaceable by JFETs of similar Idss values)
Electrolytic Capacitors:
C1: 10uF 16V -> MUSE (unipolar) 10uF 16V
C2: 10uF 16V -> MUSE (unipolar) 10uF 16V
C3: 1uF 50V -> Film 0.56uF 50V
C4: 1uF 50V -> Film 0.56uF 50V
C5: 10uF 16V -> MUSE (unipolar) 10uF 16V
C8: 0.22uF 35V -> Film 0.22uF 50V
C11: 1uF 50V -> Film 0.56uF 50V
C19: 100uF 6.3V -> MUSE (unipolar) 100uF 16V
C20: 0.22uF 35V -> Film 0.22uF 50V
C21: 1uF 50V -> Film 0.56uF 50V
C27: 10uF 16V -> MUSE (unipolar) 10uF 16V
C30: 10uF 16V -> MUSE (unipolar) 10uF 16V
C37: 1uF 50V -> Film 0.56uF 50V
C39: 1uF 50V -> Film 0.56uF 50V
C40: 100uF 6.3V -> MUSE (unipolar) 100uF 16V
C41: 100uF 16V -> MUSE (unipolar) 100uF 16V
Has anyone tried these mods before? He said he found them online. I would go meet him to test it, but he lives 90 miles away.
