Need help - saving a botched QRX-5500A

Just wish I could get the dial and tuner meters to stay on all the time!
I ran a wire from the lamp power supply (connection point 2 on F-1483) to the appropriate point on the illumination board (F-1470). Dial lights and the signal strength lights now stay on for all sources. To get the tuning meter light to stay on is tricky, since it is connected to the power for the FM indicator light. If you wire the tuning light to stay on, the FM light will also stay on regardless of source.

Excuse my ignorance about electrical laws as I am just a hobbyist and still learning, but couldn’t one also just run a wire from the lamp supply to one of the leads on the dial lamp (to feed it and the tuner light)?

We're all still learning! :thumbsup: I've shown on the schematic bellow where I ran a wire, basically bypassing switch S701Q which turns on the dial lamps and tuning strength meter lamp only for AM, and the two FM switch positions. S701h position determines which indicator light is powered.

Hello sir! And thank you for your patience with my long overdue response (been busy getting ready to go back to grad school in a few weeks)

Excited to report back that 02 on the power board was exactly what I needed - I jumped that to the appropriate spot on the AM dial, then that to the FM dial, then that to the negative of the rear quad meters (which are wired backwards from the front) - I also cut the wire between the FM dial and the indicator light so the FM indicator does not stay on unless set to FM.

And because I like the little red light as well, (though not accurate to function) I jumped the stereo light to be on all the time, technically accurate to all functions except from the tuner but super easy to un-do if ever needed.

Sounds unbelievably good - easily comparable to my fully rebuilt 9090. When I have time one day I’ll likely go through and rebuild the driver, quad, and pre amp boards as well. Thank you again for your help!

Beautiful! :thumbsup:

What's the unit on the shelf below with the large meters?

That is a Douk selector box - it lets me swap between two amplifier inputs and two speaker outputs. Though in practice it’s mainly used for the pretty lights and dancing meters that can also be set to be sensitive to decibels rather than signal input. It is sitting on top of a CD player, and next to an RCA selector box that lets me plug three aux inputs into the same jacks on the receiver.
