Zener Diode replacements

Hi I am looking for replacement zener diodes for the following Sansui Amp components:
RD24F
RD18F
RD33F
Any suggestions would be greatly appreciated.

Thanks

Hello StOnEfIsH, welcome to the DigiKey Techforum.
According to the Datasheet I found on-line, these are 1W zener diodes.
Possible alternates are:
112-ZPY24-TRCT-ND for the 24V zener.
112-ZPY18-TRCT-ND for the 18V zener.
ZPY33-TRGICT-ND for th 33V zener.
Please check the datasheets to verify compatibility to your application.

Hi David

Thank you for the information, I will review tonight.
I also have a number of obsolete transistors, I will put together a list tonight also. Really appreciate the help.

Kind regards

Hi David.

Thank you for the advice, they looked reasonably compatible and in the basket!
If you dont mind, please can you give me some direction on the following transistors:
2SB607
2SB636
2SC1047
2SC1636
2SC1645
2SC1674
2SC1845
2SK117
Thank you, I appreciate all your help.
