Hello all! I am sorry if this is in the wrong section, if it is please let me know
I'm repairing a Technics SU-V707 Receiver, the pre amp stage had a few components blow, and of those I've found replacements for all of them but two diodes. Technics is a Panasonic brand, so the diodes are Panasonic models.
One is a 20A90 Geranium diode, which I had a hard time finding specs on, however I think I have found a suitable Schottky replacement - here.
And the other is a MA2 Series MA2B027WA diode - here. It is some kind of variable resistor diode, which I cannot find a replacement for. I was curious if I could use a TVS diode in its place?
Here is a snap of the circuit they are implemented in - here.
Diodes D316 and D326 are the diodes of quesion.
Any help or suggestions would very greatly appreciated!
Thank you all for your time.
