Dead Oracle

Help my Oracle power supply hs given up t ghost andi cannot aford the replacement a it would cost nearly 2000.00 pounds I am retired so i am after a second hand one. We have tried to fix it and found that the drive transistors which activat the Hall efect mor are kaput but I cannot find the equivalent. So if any one has any of these spare or have an idea to sort the problem i would really appreciate it as there are 2000 plus records to play TIA
