Hi All as a hobby i restore Valve sets mainly from the 30s I have used blue tooth receivers which work well to give them a new lease of life using the gram input
A friend recently asked us to take a look at his Rockola Jukbox sufferings from distortion. It’s been restored in the past the fault was found just to be dirty pre amp valve base. I used a my bluetooth receiver into the amp and the sound was was very good. But switching inputs has been a problem. I tried audio relays and using a 4066 audio chip but the sound quality wasn’t great so not sure if it’s possible. Also the amplification from the bluetooth device has reduced yet it’s ok from the phono input any advice would be appreciated
