Vintage Synth Repair

The spring reverb of my Farfisa Compact combo organ is defect. It 
appears to be due to a broken phono cartridge. The cartridge is: Acos 
GP 71. Where can I find these things?

Hello Matty:I have a lot of different spring reverbs that I usually sell for 
$10.00 + shipping most of them are from Hammond organs but I do have a 
variety,you need to know the input and output impedance(A.C.ohms) of the 
coils on the end to get a proper replacement,you can usually measure this 
with just an ohmmeter but it is important to find this out or your 
replacement unit might not work.this can be measured right at the RCA 
connectors on the reverb tank,also you can sometimes get an idea of the 
values by the color of the bobbins that the input and output coils are 
mounted on.this might be yellow,red,green,white,blue etc.if you have any 
other questions just post them.
regards.
