Hi I'm a New Member here I recently purchased a Kenwood VR-309 off of ebay and when I played it yesterday it ran really hot to the touch so this afternoon I called kenwood changed some settings under menu settings and turned off all the surround sound modes and any unused channels. Adjusted the distance of my Rear Surround Sound Speakers. (using them as mains) Everything is now PERFECT No more excessive heat build up and no longer getting hot to the touch. What are your opinions on this nice older Stereo Receiver Amp? Original MSRP was $400.00 in or around 2001. I love the Sound Quality and the features it has.

Hello,
I know some might say... just buy another one. Sell it as parts..!
So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.
Spent some time downloading the Service...06-11-2024, 08:38 AM -
Hello all. I'll try to keep this short. I have no knowledge of electronics. I can use a multimeter and am familiar with caps to some extent. I bought a Kenwood KR-6030 vintage stereo. It need work and so I thought I would recap the thing since I get power to the on switch but nothing else is working. No lights, no sound and so forth. I went to Mouser to order caps and I find I am way over my head. I not only do not know the type of capacitors I need but Mouser and digikey do not accept Kenwood part numbers. I have the info such as 220uF 63v and such but no place to put it. I could buy a recap...

I am Repairing this unit. It had many problems. One major one was the power transformer being about 4-5 volts low on the main B+ line which called for 66.5 Vols after the Main Filter caps but only showing about 62 Volts. Caps and the 5 amp Diode bridge were replaced which helped slightly.
The other strange problem was the small secondary winding from the PT which supplies 18 Volts AC to the "FM FLUORESCENT DISPLAY" circuit, and the small winding that supplies 8 Volts AC to the push button grain of wheat lamps. Those voltages were down from 18 Volts to 16 volts. Which was... -
More Lo-Fi speakers and another DIY surround repair.
The patient this time: a pair of Philips F9217L-50R speakers from a budget Philips rack/component system from the '80's. The system belongs to my brother in-law… or actually his parents. However, they didn't want it when they moved houses and he liked it anyways, so he ended up keeping it. It's a pretty cool-looking vintage system with a wood/veneer cabinet and shelves for records and cassettes. Unfortunately, I didn't get a chance to take a picture of it or get the model #'s (but maybe next time I visit, if anyone is curious?)

Hello everyone, I have decided to try and replace the mosfets in my power amp (the one with relay and left and right sides) on my kenwood kr-6030. I'm trying to get the A side of my speakers working. I have replaced all the caps in the power board and I thought why not change the mosfets. They seem to be working since I have great music coming out of the B side speakers and since I am not an electronic guru (but I am learning) I don't want to make any mistakes. The mosfets I have are listed A913 so I guess 2sa913 and 2sc1913. Can't really find those in mouser or digikey at least with the info...
