Hello All,

I am having trouble tracking down a MC1495 or SG1495 or 1826-0437.

Its a 'wideband linear 4-quadrant multiplier' used in the AM and
Amplitude levelling in a 3325A.

Does anyone sell this chip anymore?

Is there a functional / electrical equivalent?

Best regards,
Mark.

PS I have 3x A3 boards, all with the same problem!
Symptom is A-Cal fail, All 3 self test fail.
The voltages around this IC are all wrong.
