Hi all, got myself a cheapish GE-7 off of evil-bay, hiss as you would expect. So I get some opamps at the ready and some new caps, going to mod it monte allum stylee ;)
problem though. My board is later than the board I have seen reference to prevously on a mod I have seen before. IC 1 2 3 are JRC 5011G I cant even find a pinout for them :s IC4 is usually a 8pin DIL JRC4558 on this its a 8 pin all in a single line chip JRC 5034G
infact the board is completely different to what I have seen before. Anyone know about this for modding? I am thinking thats the labelling is the same on the board so R1 is the same on this board to the previous but dont know
ideas appreciated
If you send me a gut shot I can compare it to mine. Mine's an old MIJ. Someone will probably beat me to helping though... ;D Gotta love this place.
I just changed the 3 op-amps for TL082's (I was a little short on 072's) and replaced the 3 1uF electros for film. left everything else as stock. Much quieter
