B & K AVR 507 Series 2

[jlr]

I have a B & K AVR 507 Series 2 unit and one of the power supplies has gone bad. Since B & K is no longer around, parts are not available. Any suggestions for what to do with this unit as for as repair or use in conjunction with other amplifiers, or is it time to move on. The unit was set up to power 5 speakers in theater setting and 2 speakers for stereo listening in a separate room.

If the part isn't available repair may not be possible unless that particular power supply is available outside of BK. It's like 24 years old, tho and personally I'd move on....otoh if you have pre-outs that still work fine you could add external amps....

I would move on. So much has changed since that was released. A modern 7.2 channel Denon for instance will come with room correction, decode more formats, more input/output options, and have a host of other useful features. All around $1k.

The unit is a boat anchor in need of a one way trip to the recycling center.

That's strictly an analogue unit so I would only consider repair if you have no intention to ever add any digital sources. As long as one one the transformers has not gone, the power supply should be repairable but what else could be wrong and how much money do you want to put into a 20 year old AVR? Only issue I can foresee is what are you using for source material? Newer AVRs have a limited number of analogue inputs. If you have a lot of analogue sources, you may run out of inputs, so I would research that first.

You also have not mentioned what type of display you are using. If it is an analogue display that could be an issue because modern AVRs all use digital HDMI outputs. Finding an AVR with component out will be a challenge. Sometimes when one piece goes it may involve a complete system upgrade. When I replaced my TV, I also replaced the AVR at the same time since both pieces should support the latest HDMI spec.

Those units are absolutely no use "to man nor beast" any longer. Even if he did fix the gear connected to it will be failing. Its junk and there is no doubt about it.

That's not a fair assessment. You're assuming that the op can afford to replace the ENTIRE system due to one failed component. That might be the optimal solution for gear that old but not an assumption I would make. We need a detailed list of what the op owns to know whether it's worth getting a little more life out of the current setup. I had to save up for years to purchase a complete system. Repairing one component could extend the life of the system enough for someone to do that. If the TV / projector is also that old then we're potentially talking thousands of dollars.

If the TV has HDMI and component inputs then a new AVR would be best. If you look at the higher end of Denon and Marantz AVRs, some models still have a decent number of analogue inputs, but the choices get more limited each year.
