Hi Chaps, first post. I have bought a dead Spider 2 210 with hum on sound and channel selection knob broken.
Fixed the channel selection then the OUTPUT LM 4796 blew in a lot of black smoke. I found the insulator washer had been compromised.
Changed that then still no output. A couple of other guys had the same problem. Mine was the -5v was down to -0.7. (Large signal inputs , or switching to the INSANE channel gave a very low and crackly output which was very intermittent.) SO changed the 79L05 -5V regulator for another and that worked great. Now I have sound. Then found the treble and Rev do not work. No its not the pots! I checked the volts to the pins of the TLC542. The volts were OK so I now have to change the CHIP. will it ever end? One question , how loud is the clean channel suppose to be on these stereo spiders ( yes no bridge in this just seprate channels). Mine isnt that loud although on insane it nearly tears my ears off ... Cheers all hope this post might help some one.
