Title: Need recommendation for AVR’s memory capacitor replacement
Post by: g.costanza on August 17, 2024, 06:53:15 pm

Picked up a very nice Harman Kardon AVR110 surround sound receiver for $10. Has common issue of bad memory capacitor. All settings are lost if power is cut. Can someone recommend an inexpensive replacement, shipped to Georgia, USA? I’d hate to spend $10 on a part for a $10 device. Lol. Does it have to be the same type? I do have some old circuit boards from other amps etc I’m also going to scrounge through to see if they have the part. Thanks!

Just about any 5.5 volt 0.047F (or more) supercap should be OK

Anywhere official is going to be like $3 + shipping.

Aliexpress is probably your best bet for ultra cheap options with free shipping. But quality might not be the best
