Hello group,

Looking for replacement ND487C2-3R for a very old
FT-77, thats really reduced modulated phone power
(less than a watt, but does well ok CW). This device
is a double balanced modulator, ring, 50 mA, silicon
schottky barrier diode. Any tips on replacement
greatly appreaciated. 

I'm in VU land, India. 

73 & tnx for reading
de Sri, VU2SBJ
