If your Denon AVR has a broken or dysfunctional plastic stemmed VOLUME control (fits into large top right plastic knob), and you're mechanically inclined, here's a rare offering for a replacement.  Biggest issue is opening your receiver, removing the PCB from the front panel, de-soldering the defective control, replacing and reassembling......please don't attempt if you're not comfortable with this procedure.  You will receive a fully functional control similar to the one pictured, removed from a receiver scraped for other issues.  100% guarantee of satisfaction....if any issue, promptly return prepaid for full refund.  Shipping via USPS First Class Mail with tracking is $4.00 total for as many controls as you order.  Will ship to USA only……no international shipping!!
