[QUOTE="DJDAN, post: 4724, member: 390"] I bought a dead RG75 G2 amp for 20 $ at garage auction. I did all the tests and found only two blown up semiconductors in the preamp circuit. I tried to find the parts at three electronics parts suppliers. Nobody find the parts in any catalogs and, of course, cannot find any equivalents. I tried my luck on the Internet : nothing. So : - Could you tell if there are any equivalents parts I could use for replacement (with the references numbers) The parts are : 1) One 8 pins semiconductor (Op Amp) with the number 0720 JRC 4034B. The place on the preamp board is IC11 somewhere in the master section or in the clean channel 2) One transitor with the number J103 BL3L. The place on the preamp board is Q9 somewhere in the master section or in the clean channe Where can I find the schematic of the RG 75 G2. I will appreciate any informations that could help me to ressusitate that bone crushing amp. Best regards [/QUOTE]
