Morning!
Your 1610's are dual diodes rates at 16 amps at 100 volts the R designates Reversed polarity, So one will supply positive voltage and the other will supply negative voltage. These are the main rectifiers for the amp
The LM7915ct is a 15 volt regulator, and if you look next door a LM7815 should be there, this is another 15 volt regulator. You can also use just about any three terminal regulator as a replacement just as long as they supply the current level of the original part
If you type these numbers in your internet search browser you should get the PDF's for each device along with a whole bunch of suppliers worldwide.
Hope this helps abit
