My grandpa got this receiver some 20 years ago and it has been working great until this past week when I turned it back on but did not hear the relay "click." I know this is a relay problem (I've heard many people with this problem), and I am looking to replace the relay but the issue is finding the correct relay. I took apart the receiver and located the relay. It is a Takamisawa VB 24MBU-501 24VDC. I am having trouble locating this relay anywhere online and I was wondering if anyone could help me locate it or help me find a replacement? I think it is a very old relay and may be discontinued now. On the back it has some specs but I am not sure what they exactly mean. It says 1/6HP, 120V/240VAC, 5A, 24VDC/240VAC RES. If anyone could help me out that would be great. Thanks!
