Hi Deebo check the following website www.dalsani.com www.repairworld.com good luck open the set and you will find the part number printed on the body of the component. NB.but i am in the belief that it IS your IC that is damaged.

SOURCE: Noisy channel of receiver

Generally, crackling noises come from anyplace there is a mechancial connection for the sound signal. The volume control, main/remote speaker switch and possibly the headphone jack. That is where the contacts must be cleaned, but it requires dissassembly. Try operating the main/remote speaker switches, and plug/unplug a headphone several times. I am assuming there is still audio behind that crackling. Are you using both main and remote speakers simultaneously?

SOURCE: my reciever volume cuts in and out and crackles when adjusting

You can CLEAN / LUBRICATEthe volume control know with a CONTACT/CONTROL cleaner, I use a product from Radio Shack, this works wonders on drum type electo mechanical devices which are basically volume control knobs, easy to do, just remove the round knob and spray into the openings with the small tube attached, and rotate in both directions, be sure to unplug the unit first, on a few occasions it is best to remove the front panel to acheive better coverage to the rheostat type volume body, anyway it always cures the crackling and distorting sound, I would give this a try before replacing the part.

SOURCE: Max. wattage for speakers w/ Technics Receiver SA-GX100?

I too have a Technics SA-GX100 and it's rated at 2 x 40W @ 8 Ohms. I have the Technics SB-2840 floor model speakers hooked to it, which are rated at 200W Music Input - 8 ohms. It sounds very nice just to be a 40W receiver.
