Kenwood KR-9600 Receiver (1978)
Perhaps not as well known as the Pioneer SX-1250 or the Marantz Model 2500 but those in the know recognize this monster Kenwood is firmly in the same league. There's a 3-stage differential amp, Dual Power-Supply (but one transformer only), four large caps, sizeable side heatsinks, relay switching, DC and overcurrent protection for the amp section.
You can own this fine example (with original manual included) for just $450+ shipping. Contact us for more details.
