------Question for 1S2075K-J Please Put your question below------
What would be an equivalent or replacement for a 1S2075K diode and a 1S2076A diode for vintage audio equipment?
Hello @cusooner,
The 1S2075 and 1S2076 have low leakage, low forward drop, and low capacitance. It is challenging to find an exact substitute with all of these desirable attributes.
Recommend:
Please let us know where the diodes are used (MFG and model number of the equipment). This may help us refine the recommendation.
Sincerely,

Thank you for the quick reply.
They will be replacements on the Amp board on a Realistic SA-2001 intigrated amp.

Hello James,
That’s a beautiful amp! Ref: https://www.hifiengine.com/
With respect to the diodes, I see them used in the power amplifier:
-
Clamping D604, D605, D606, D607
-
Regulation D602, D603
Unless absolutely necessary, I would not modify D602 and D603 as this will change the bias of the input stage. Then again, most circuitry is forgiving but the proof is in the working circuit.
Sincerely,
Aaron

Thank you.
Will definately take your advise.
Getting back into component repair after about 35 years.
The trouble-shooting aspect has not been bad but trying to to get replacements for the components has been more challenging.
Your help is greatly appreciated.
I really apreciate you and the forum.
