* This is a used set bought off of eBay. Someone recapped this board in 2003, replacing most of the existing capacitors with Panasonic SU series. However, these Panasonic SU capacitors have a negative stripe on them and there are polarity markings on the circuit board. Therefore, it is assumed that these are regular "general purpose" capacitors.

* There is a capacitor in the Original Parts list labeled C185P2. This is because there are 2 capacitors labeled C185 on this board. If doing a bulk recap, you will need to buy both capacitor C185 and capacitor C185P2.

JVC RX-208BK
Preliminary Information
Release Year 1994
Leak Risk Medium
Batteries None
Mounting Technology Through Hole, SMD, BGA, Sockets
Capacitor Types Aluminum Electrolytic, Tantalum, Ceramic, Polymer
Destructive Entry No

The JVC RX-208BK is a stereo receiver released in 1994. It has the ability to drive up to 2 sets of 2 speakers. It has 2 stereo RCA inputs, a phono input, and a built-in AM and FM radio.

Notes:

  • This is a used set bought off of eBay. Someone recapped this board in 2003, replacing most of the existing capacitors with Panasonic SU series. However, these Panasonic SU capacitors have a negative stripe on them and there are polarity markings on the circuit board. Therefore, it is assumed that these are regular "general purpose" capacitors.
  • If anyone has a service manual or schematic for this model, upload it to archive.org and post a link in the Discussion section of this page.
  • There is a capacitor in the Original Parts list labeled C185P2. This is because there are 2 capacitors labeled C185 on this board. If doing a bulk recap, you will need to buy both capacitor C185 and capacitor C185P2.

Known Issues

Disassembly Notes

There are a few white connectors on this motherboard. on these connectors, you will need to push down to remove the cable from the connector. When reinserting the cable, push down on the connector first.
